1. Introduction The functioning of the electricity market depends entirely on metered data being obtained and energy statements being prepared unequivocally defining each individual grid company and outlining the geographical areas of responsibility of balance responsible parties (BRP). In this regulation, the roles of grid company, metered data collector, metering point administrator and the concept of grid area are defined. The regulation also defines which types of metered data are required in connection with electricity generation, grid flow between areas of responsibility and end consumption. The regulation describes how often the various metering points must be metered. Meter data must be submitted to Energinet.dk and other legitimate recipients. This regulation describes the requirements that apply to the submission of data in relation to the following questions: - Are data from the individual metering points or aggregated meter data to be submitted? - What deadlines apply to the submission of meter data? - What quality requirements apply to the meter data submitted? - Which sign convention must be used when submitting data? Energinet.dk uses submitted meter data for computing energy statements to be used in connection with the settlement of grid companies and other players. This regulation describes how these energy statements are computed and how the computations are made for the grid areas where there are autoproducers using net settlement. TIME RESOLUTION Denmark is divided into two TSO areas: Western Denmark and Eastern Denmark. Historically, in the two areas, metering has been performed and energy statements prepared using different time resolutions. Western Denmark uses quarter-hourly registration, while Eastern Denmark uses hourly registration, see section 8.4, however. This means that in this regulation concepts such as quarter-hourly or hourly registration are used. For the sake of reader friendliness the two concepts are collectively called "15/60 registration". As such: 15/60 value must be read as quarter-hourly value by West Danish players and hourly value by East Danish players. 5/55

2. Definitions 2.1 Definition of grid company Grid companies and transmission companies are grid owners who in pursuance of the Danish Electricity Supply Act are granted a licence to conduct grid or transmission activities. In this regulation, the designation grid company is used for both types of companies. Transformer associations and other grid owners who have not been granted a grid licence are not considered to be grid companies. Owners of generator feeders, electricity generators owning internal grid facilities and end consumers owning internal grid facilities are not considered to be grid companies. Settlement of transformer associations and other grid owners without a grid licence will be administered by the grid company in whose TSO area (grid area) the grids of the grid owners concerned are located. 2.2 Metered data collector Any given metering point has one and only one metered data collector. The metered data collector for a metering point is the grid company that administers the grid in which the metering point is located. When metered data are exchanged between two grid areas, the responsibility for performing metering must be unequivocally agreed upon for each individual point of exchange between the two grid companies concerned. Grid companies may be responsible for performing metering in grids not owned by themselves, eg metering of production facilities feeding electricity to the grid company's grid, and where the metering points are located in the generation facility's grid (eg the metering of energy that need not be included in a facility's own consumption for electricity generation). The metered data collector must be granted access to all metering points for which it is responsible. Grid companies are responsible for operational and settlement metering. Data obtained from operational metering are used in connection with operational monitoring and system operation analysis. (See more about requirements for operational metering in Energinet.dk's technical regulations.) Data obtained from settlement metering are individual, aggregated metered data to be used in connection with energy settlement. The metered data collector is obliged to: - ensure that metering is performed - to transmit remote-read metered data - check that metered data are correct - distribute meter data to legitimate recipients Metered data collectors must guarantee confidentiality/discretion where meter data are concerned. 6/55

2.3 Metering point administrators A metering point administrator is an enterprise charged with handling all practical matters in connection with metering and meter data distribution. The metered data collector may choose to act as metering point administrator himself or to outsource the particular task to another enterprise. A metered data collector may use several metering point administrators. Acting as metered data collector involves practical metering tasks which can be delegated to a metering point administrator, but the actual responsibility for the metering tasks cannot be delegated. A grid company delegating a metering task to a metering point administrator is still financially and legally responsible and must ensure that all practical tasks are handled by the metering point administrator. Metered data collectors must guarantee confidentiality/discretion where meter data are concerned. 2.4 Definition of grid sections and grid areas A grid section is a physically interconnected grid. Geographical definition: A grid section is delimited unequivocally by a number of 15/60 registered grid nodes connecting the grid section with adjacent grid sections. A grid area consists of one or more grid sections. A grid area typically consists of one grid section, but may consist of several, provided these are not directly and physically interconnected. A grid area defines the grid which is owned by a grid company and/or administered by a grid company for settlement purposes. Grid areas are divided into: - Local grid areas (0.4-33 kv grid and possibly 50/60 kv grid) - Regional grid areas (50/60 kv grid) - Transmission grid area (132/150/400 kv grid) - Special grid areas established for settlement purposes 1 and - 50/60 kv regions. In a 50/60 kv region the electricity consumption in local grid areas and in one regional grid area is compiled for settlement purposes. Typically, a grid company is responsible for one grid area, but a grid company's area of responsibility may be divided into several separate grid areas if for settlement purposes it is necessary to compute the total electricity consumption across several grid companies' grid. This could happen if, for example, the grid which is administered by a grid company comprises several 50/60 kv regions. 1 Such a 'special' grid area may consist of a single end consumer, eg Banedanmark in Western Denmark. 7/55

The number of grid areas is thus determined by Energinet.dk in cooperation with the grid company on the basis of settlement requirements. If the grid company covers by several grid areas, Energinet.dk will compute the electricity consumption separately for each individual grid area. The total number of grid areas determines the total electricity consumption and generation in the Energinet.dk area. 8/55

3. Duties of grid companies 3.1 Metered data All grid companies that are metered data collectors are obliged to ensure that metering is performed and that metered data are distributed as described in this regulation. 3.2 Balance responsibility for consumption Grid companies are responsible for ensuring that an agreement on balance responsibility is concluded for the grid loss administered by the grid company. All grid companies must at any given time be able to document how the total consumption is distributed on BRPs. The documentation must specify which consumers have concluded agreements with which BRPs. Energinet.dk must be given access to this documentation upon demand. The grid companies' other duties in connection with the administration of metering points and associated BRPs for production can be seen in Regulations A and H1. Energinet.dk handles the administration of metering points and associated BRPs for consumption in the following instances: - End consumption in special grid areas. - Grid losses in 60 kv grid areas 3.3 The grid company's role in settlement As a main rule, grid companies are the smallest organisational unit for which Energinet.dk states the electricity consumption and establishes direct settlement procedures where the collection of PSO costs as well as grid and system tariffs is concerned. Energinet.dk receives meter data and calculates on this basis the various tariffs and subsidies etc. These statements are sent to the grid company, which settles the underlying grid companies and a few consumers/generators. As from 1 October 2007, Energinet.dk will settle subsidies and possible market value (including grid tariff for generation) direct with the generators. The electricity consumption computed for a grid company is also important when it comes to settling transmission services with other grid companies and determining the balance responsibility for consumption in Energinet.dk's area. 3.4 Confidentiality The responsibility for metering is thus closely linked to companies which can be granted a grid licence. When a grid licence is granted, the company to whom the licence is granted must comply with the requirements concerning impartiality and discretion and check that units connected to the grid comply with current technical specifications at all times. 9/55

Grid companies acting as metered data collectors may delegate some of their metering tasks, but the principal responsibility for ensuring that tasks are solved in a competent manner and that data are treated confidentially and independently of commercial interests always rests with the grid companies. As such, the grid company must prepare written procedures which in case of doubt can demonstrate that conditions have been complied with. Energinet.dk's discretionary policy and data protection procedures can be seen in Regulation G. 3.5 Master data The grid companies are obliged to provide Energinet.dk with master data to be used in national master data registers. This means that the grid companies are responsible for collecting and updating master data for all electricity-generating facilities in the grid companies' grid areas. The grid company is responsible for collecting the documentation necessary to verify the master data registered and passed on by them. Grid companies must: - Collect all master data relating to the grid connection of new facilities. - Update master data in connection with, for example, plant reconstruction or changes of ownership 2. - Report the decommissioning of facilities. Information is reported to Energinet.dk via its self-service portal. In addition, Energinet.dk must be able to obtain all the necessary master data about grid facilities from the grid company in whose grid area the grid facilities are connected. 2 As from 1 October 2007, plant owners must report changes in ownership direct to Energinet.dk. After this date, grid companies need only submit owner information when new facilities are connected to the grid. 10/55

4. Data exchange procedure - deadlines and quality assurance This chapter outlines the procedures for data exchange and fixing as well as refixing in connection with the ordinary correction settlement. The deadlines for submitting data and data quality requirements in connection with the data exchange are described, and legitimate recipients of meter data are also defined. "Working days" are defined by Energinet.dk, who has set up a calendar at www.energinet.dk specifically designating which days are to be considered as working days (see also Annex 2). 4.1 Data exchange Data exchange takes place via Ediel in accordance with Regulation F 3. When time series are submitted (and resubmitted), the grid company must submit the time series concerned to all legitimate recipients at the same time. Simultaneous submission must be used in connection with individual time series for each metering point and all aggregated series in which individual time series form part. 4.1.1 Procedure until the third working day after the day of operation The metering point administrators must submit 15/60-registered time series to all legitimate recipients not later than at 10:00 on the third working day after the day of operation. The grid company must check the time series before distributing them to the legitimate recipients. DATA CHECK Before time series are first distributed to legitimate recipients, the grid company must implement a series of quality controls aimed at ensuring a well-defined data quality level. The grid company must replace missing or faulty values with the most accurate estimates possible (replacement values/estimated values). Grid companies' check of missing or faulty time series comprises the following: - Missing values - Sign errors - Zero sequences where the value should not constantly be zero based on the grid company's knowledge about the metering object - Meter values lying outside what is technically possible (max./min. control). In case of missing/incorrect meter data the values concerned must be replaced by estimated values. The estimated values can be determined either by: - Using data from a check meter (is obligatory where check meters are available). Energinet.dk's Regulation F has not yet come into force. Until this happens, reference is made to Eltra's regulation E1 and Elkraft System's regulation F1. 11/55

- Rescaling time series from another metering point in the same category and with related master data where meter data are available for the day of operation. - Using a time series from the metering point for a previous day of operation which is similar to the current day of operation, eg a time series from the previous day or the same weekday in the week before. - Using master values giving due consideration to any information about actual operational disturbances in the metering point concerned, eg breakdown of an electricity-generating facility. - If a total meter value is available for the 24-hour period, it can be distributed on a 15/60 basis on the basis of empirical data. The estimated value must never be set to zero unless the grid company is in possession of knowledge rendering it probable that the meter value is zero. Faulty and defective time series for individual metering points must be corrected before compiling aggregated time series. Faults in aggregated time series can also occur as a result of faults in aggregation keys. The grid company must therefore monitor the continuous updating of the aggregation keys. The deadlines and quality requirements outlined above are mandatory and must be observed. In accordance with sections 85(c) and 86 of the Danish Electricity Supply Act, the Danish Energy Regulatory Authority may order the grid company to pay fines. 4.1.2 Quality code for time series (Ediel message) If a time series has been categorised as "preliminary values", it must be resubmitted prior to fixing at 10:00 on the fifth working day after the day of operation to all legitimate recipients with all values being categorised as "final". It is not a requirement that estimates be distributed as "preliminary values". If the time series has been checked, and faults and defects have been corrected and remedied in accordance with the procedure outlined in section 4.1.1, it can be submitted with all values being categorised as "final". The rules are described in more detail in Annex 7. 4.1.3 Procedure from the third working day until the fifth working day after the day of operation Between the third and fifth working days the values already submitted are checked by the parties involved. 1. The grid company reviews the distributed values, including any preliminary values. Any preliminary values must be replaced by final values before the fixing on the fifth working day after the day of operation. 2. Legitimate recipients of time series may contact the grid company and point out any faults and defects. 3. Energinet.dk reviews, validates and checks the time series received. All time series received will be checked, and this includes a check of the use of 12/55

signs as well as a max./min. check. It will also be checked that preliminary values have been replaced by final values. Furthermore, Energinet.dk checks that the time series received constitute a consistent whole for the TSO area (Energinet.dk checks, for example, the overall energy balance and checks that the correct sign has been used for the residual consumption in all grid companies, etc.). Data transmission faults and other obvious faults must be clarified with the grid company. If the time series contain any faults or preliminary values, the grid company will resubmit them (see section 4.1.5) 4.1.4 Procedures to be implemented from 10:00 am on the fifth working day after the day of operation and later If faults are found in time series already distributed for a day of operation, the grid company must re-submit them simultaneously to all legitimate recipients. 4.1.5 Re-submission If the grid company has found faults or defects in time series previously submitted, such faults must be corrected and all the time series affected re-submitted simultaneously to all legitimate recipients (see section 4.1.). This applies irrespective of when the fault is discovered. It is a precondition for re-submitting time series that the recipient's system is open and capable of receiving time series. Faults may result from metering errors, including problems in transmitting meter values. Faults in aggregated time series may also result from faulty aggregation, eg in connection with a change of electricity supplier 4. A fault in a time series will cause faults in all other time series of which it forms part through aggregation. As such, one metering fault normally results in corrected time series having to be distributed to many legitimate recipients. Normally, it is not allowed to re-submit corrected time series together with noncorrected time series. As an exception, it is possible from 10:00 on the third working day after the day of operation until the fixing (10:00 on the fifth working day) to re-submit all time series when a grid company's initial distribution of time series was incomplete - typically because of IT systems breaking down (force majeure). If re-submission takes place before the fixing for the day of operation concerned takes place, the changed values are incorporated in the time series on which Energinet.dk bases the fixing. ALLOWING AND DISALLOWING THE RECEPTION OF TIME SERIES AND STANDARD FAULT REPORT Energinet.dk disallows the reception of time series after the initial distribution of time series at 10:00 on the third working day after the day of operation. This makes it possible to control when a time series stored in Energinet.dk's database is automatically overwritten on the initiative of an external user. 4 The submission of a time series as 'preliminary values' is also considered a fault. 13/55

Energinet.dk opens up for the reception of time series following a telephonic request from the grid company. After the fixing time, ie 10:00 on the fifth working day after the day of operation, the grid company is also required to fill in a standard fault report (see Annex 3) before re-submitting a corrected time series. The standard fault report is submitted simultaneously by the grid company to all legitimate recipients of the time series concerned. The fault report must not contain non-corrected time series. All fields in the report must be filled in, including the explanatory field, which Energinet.dk uses for preparing fault type statistics. A standard fault report must be distributed each time a time series is resubmitted after fixing - possibly by email. 4.2 Fixing and balance settlement performed by Energinet.dk Energinet.dk fixes its data basis for one day of operation at a time at 10:00 on the fifth working day after the day of operation. Fixing means that the settlement basis is filed, ie an updated copy of the time series (in aggregate form) is filed at the fixing time mentioned. The balance settlement's data basis consists of the fixed data set. Energinet.dk sends the fixed basis for the imbalance settlement to the respective BRPs and grid companies not later than at 16:00 on the fifth working day after the day of operation. In Annex 5, an overview is given of the information about the electricity consumption in the grid areas which Energinet.dk sends to grid companies and BRPs for settlement purposes etc. FORCE MAJEURE IN CONNECTION WITH ORDINARY FIXING In certain circumstances it will be most expedient for all parties if Energinet.dk decides to postpone the fixing. The force majeure conditions are outlined in Annex 8, which also states which information Energinet.dk must provide in such situations. In these instances, the submission of the fixed data basis may also be delayed. INVOICING Ordinary balance settlement is invoiced on a monthly basis. In special cases where there is a risk that Energinet.dk may suffer a financial loss despite security being provided, invoicing (including daily settlement) may be performed more frequently. 14/55

4.3 Energinet.dk's correction settlement Ordinary correction settlement is a type of settlement that corrects the settlement between Energinet.dk and the BRPs. In this manner, the mutual settlement between the BRPs is also corrected. Correction is made for metering and aggregating errors ascertained in the time between fixing and re-fixing (see below). Settlement adjustments between electricity suppliers using the same BRP are governed by the agreements made between the commercial players and are of no concern to Energinet.dk. Ordinary correction settlement takes place for one month at a time three months after the ordinary balance settlement. The deadline for the submission of a standard fault report for time series for correction settlement is: 10:00 on the 15th day of the month concerned or at 10:00 on the first-coming working day if the 15th is not a working day. The settlement basis for the correction settlement is locked at this time (called "re-fixing"). The same balancing power prices that are used in connection with the ordinary balance settlement are always used for the correction settlement. After re-fixing, Energinet.dk will definitively refuse the receipt of corrections of end consumption per BRP metered on an hourly basis. Other types of corrections in the form of re-submissions are received subsequently if it becomes necessary to correct any faults in the settlement of subsidies, tariffs, statistics, etc., but the balance settlement will be completed with the correction settlement. Re-fixing thus means that the settlement is filed, ie an updated copy of the time series (in aggregate form) is filed at the fixing time mentioned. The January settlement correction takes place in May, the February settlement correction in June, etc. After re-fixing, Energinet.dk forwards the re-fixed correction settlement basis to the respective BRPs and grid companies (see Annex 5). The deadline for performing re-fixing and correction settlement can be postponed in force majeure situations in the same way as described in Annex 8 regarding delayed balance settlement. If re-fixing is postponed, information about this will be available at Energinet.dk's website no later than at the time when re-fixing normally takes place. 15/55

After ordinary correction settlement, Energinet.dk does not correct the balance settlement any further. Any financial issues arising as a consequence of additional corrections will be handled on a case-by-case basis between market players, grid companies and Energinet.dk to the extent stipulated by legislation. This provides the grid companies with an incentive to correct all faults before re-fixing. In connection with the ordinary correction settlement the settlement of subsidies, grid and system tariffs as well as public service obligations (PSO tariff) is also corrected. Subsidies can be settled in the period between ordinary settlement and ordinary correction settlement. CORRECTIONS AFTER ORDINARY CORRECTION The general statutes of limitation stipulated in legislation apply to the correction of all settlements with the exception of the imbalance settlement, and Energinet.dk therefore corrects these payments retrospectively for a period of up to five years on the basis of the necessary documentation. If metering or aggregation faults occur after the expiry of the deadline for the ordinary correction settlement, subsidies, grid and system tariffs as well as public service obligations (PSO tariff) will be settled. Where subsidies are concerned, correction settlement is performed ad hoc. For the grid, system and PSO tariffs an overall annual correction settlement is prepared for the period from the end of April until the end of June in the following year. Afterwards, any correction settlements are made ad hoc. 4.4 Making the quality of time series more visible Energinet.dk publishes on its website indicators for faults and defects in the time series submitted by grid companies, in practice the so-called IFIM indicator, with a view to providing an even better incentive to submit correct time series on time. The IFIM indicator sheds light on the extent of faults discovered after the submission of time series at 10:00 on the third working day after the day of operation. In addition, a figure is published for each grid company indicating (as a percentage) how many of the monthly time series were not submitted before the expiry of the deadline. 4.5 Deadlines for submitting time series that are not 15/60 registered This section outlines the deadlines for submitting time series that are not 15/60 registered. The deadline for 15/60 values can be seen from section 4.1. MONTHLY OR QUARTERLY READ METERING POINTS 16/55

The metering point is read once every calendar month or calendar quarter as close as possible to the change of month or quarter, ie not later than on the first working day after the change of month/quarter. Metered data are reported to Energinet.dk not later than at 10:00 on the third working day after the change of month in the form of an Ediel monthly time series. Where quarterly-read metering points are concerned, the time series must be reported with a value of zero for the first two months and the quarterly energy value for the last month of the quarter. RE PRODUCTION FROM MULTI-FUEL UNITS The separate monthly time series for the RE production at multi-fuel units must be submitted to Energinet.dk not later than at 10:00 on the fifth working day after the change of month/quarter. If data cannot be finally computed prior to this time, an estimate must be submitted. The estimate can be 0 kwh. FAX-3-UNITS: Fax-3-units are generation facilities the settlement of which is based on a timeof-day tariff. Energy is therefore metered in tariff periods, and the meter values are reported by fax. Fax-3-units are only found in Western Denmark. The energy in tariff periods is reported by fax using a special form. Where quarterly-read production facilities are concerned, the form is submitted indicating a value of zero for the first two months and the quarterly energy value for the last month of the quarter. NET GENERATION DETERMINED BY MEANS OF A DEFINED TEMPLATE If the generator has chosen to calculate net generation (M1) using the defined template as described in section 6.7.1, and the unit meets the set criteria, this must be reported to Energinet.dk, who then incorporates the computed net generation in its subsequent computations. 4.6 Legitimate recipients of metered data obtained from settlement metering In pursuance of section 22(3) of the Danish Electricity Supply Act, the grid company must provide the users of the grid with the necessary information about the metering of electricity transmitted through the grid company's grid. To the extent that electricity suppliers/traders, default supply companies and other players are in need of meter values for settling their electricity deliveries, the grid company must provide the necessary information. The grid company functioning as metered data collector (in practice the metering point administrator) must thus act as an indirect supplier of metered time series (15/60 time series) for a grid area and forward them to other legitimate recipients as well as Energinet.dk. At the same time, the provisions concerning confidentiality and non-discriminatory behaviour in Regulation G must be observed. The conditions governing end users whose meters are read annually, quarterly and monthly can be seen in Regulation H2. 17/55

According to the market model, neighbouring grid companies, electricity suppliers/electricity trading companies and BRPs are legitimate recipients and are therefore entitled to receive meter values free of charge as follows: - Grid companies owning neighbouring grid areas and/or administering neighbouring grid areas for settlement purposes: 15/60 time series for metering performed on the border between grid areas. - BRPs: Aggregated 15/60 time series for each electricity supplier/electricity trading company in precisely the period in which the BRP has contractually assumed balance responsibility for the underlying consumption or the underlying generation to which the metered data refer. - Electricity suppliers/electricity trading companies are entitled to receive individual meter values for each metering point (on behalf of the customer) 5. BRP Time series - electricity supplier Grid company Electricity supplier Customer meter data Customer settlement data Customer Energinet.dk Time series for metering activity on border Other grid - company The same requirements that apply to estimated and rescaled 15/60 values apply to metered 15/60 values. The grid company is therefore responsible for distributing these 15/60 values to legitimate recipients. A player may towards the grid company appoint another player as legitimate recipient on behalf of the player. An electricity supplier may agree with the grid company that some or all of the individual time series for end consumption or generation must be sent to the electricity supplier's BRP. In such cases, the further distribution to the electricity supplier does in principle not concern the grid company. The delivery of time series in excess of what is mentioned above can only take place following an agreement with the grid company and in principle only against payment. 5 In cases when large end users trade with several suppliers and choose the BRP themselves, it must be possible for the BRP to access the individual end user's meter data. 18/55

End users and energy consulting companies are not legitimate recipients of meter data in line with neighbouring grid companies, BRPs and electricity suppliers. End users are of course entitled to know their settlement basis, but if they want to access meter data in a specific manner, they must make an agreement to this effect with the grid company or the electricity supplier. Not later than on the 25th of each month, Energinet.dk will generate an updated list of BRPs for production and electricity suppliers for electricity generating facilities. This list is valid for the following month and will be used by the grid companies for distributing meter data to legitimate recipients. With the Danish Electricity Supply Act no. 375 of 2 June 1999 the distribution companies were divided into grid companies and electricity-trading companies, possibly being licensed as a default supply company. In those instances where end users receive electricity from an electricity supplier other than the local electricity-trading company, the latter has no access to customers' individual metered consumption data. The grid company is responsible for drafting data protection procedures to this effect (see Regulation G). 19/55

5. Basic requirements for metered data obtained from settlement metering This chapter describes the requirements that apply to the metered data described in sections 6, 7 and 8. 5.1 Basic requirements Settlement metering must be performed in real time. It is, for example, not allowed to even out previous metering faults in 15/60 values recorded at a later date. In order to enable internal settlement between two grid companies or the registration of the generation at local facilities with displaced settlement point (see Annex 1), it is allowed to up or downscale the "rough" 15/60 values using a well-defined fixed proportional factor (that does not change over time) before the meter values are re-distributed. The main rule is that such a fixed proportional up- or downscaling is unacceptable where exchange metering between grid areas is concerned if this affects the electricity consumption of third parties (eg underlying grid companies) or the overall electricity consumption in one of the two TSO areas. 15/60 values are distributed as MWh with up to six decimals or as kwh with up to three decimals. 5.2 Sign conventions for the reporting of meter values For metered time series submitted to Energinet.dk and other legitimate recipients the following sign convention applies: - Exchanges with neighbouring grid areas are reported with a plus sign (+) when power flows to the grid area and with a minus sign ( ) when power flows out of the grid area (see chapter 7). - Generation flowing to the grid area is reported by means of a plus sign (+). - 15/60 time series for end consumption per BRP for consumption are reported by means of a minus sign ( ). 20/55

6. Settlement metering - generation All electricity generation linked direct or indirect to the collective electricity supply grid must be metered. There are only few exceptions. Electricity-generating facilities must be placed correctly within the grid company geography. The following main rule applies: The grid company to whose grid area the facility concerned is connected is responsible for all statements. If an electricity-generating facility is connected to the grid in more than one grid area, the responsibility for performing metering is divided between the grid companies affected. Electricity generation is classified in one of three categories. 1. Central power stations. These are power stations which for historical reasons have been subject to other rules than other generation facilities. These stations are listed on an exhaustive list, see section 6.4. 2. Wind turbines. All wind turbines. 3. Other electricity-generating facilities. This category includes all facilities other than the ones mentioned in the first two categories. For facilities listed in the two latter categories the generator may choose to use net settlement. The metering requirements for these facilities are different. The requirements are described in the section on net settlement. 6.1 Installation types and definition of metering point Electricity-generating facilities are either (A) connected direct to the collective electricity supply grid circumventing other consumption installations or (B) connected to the consumption installation (installation connected). 21/55

A Direct connection: Kollektive elforsyningsnet M3 Tovejsmåler M1 M0 Øvrigt forbrug ~ Forbrugssted Egetforbrug til elproduktion B Installation connected: Kollektive elforsyningsnet M3 M2 Øvrigt forbrug M1 ~ Forbrugssted Egetforbrug til elproduktion [Captions]: Kollektive forsyningsnet = Collective electricity supply grids Øvrigt forbrug = Other consumption Forbrugssted = Consumption point Tovejsmåler = Two-way meter Egetforbrug til elproduktion = Own consumption for electricity generation Definition of metering points: M0 = own consumption during standstill. M1 = net generation. M2 = metered electricity supply to the collective electricity supply grid. M3 = metered electricity supply from the collective electricity supply grid. 22/55

M0, M1, M2 and M3 indicate the principal metering points to be registered and communicated to the legitimate recipients. All four types of metered data may consist of a number of underlying metering points which all indicate the same type of energy flow. 6.2 Definition of net generation and own consumption for electricity generation Net generation (M1) is defined as the generator production (gross generation) less the own consumption required in connection with electricity generation. Own consumption includes: - Electricity consumed by environmental facilities at the power station. - Electricity consumed by workshops as well as public and administrative buildings. - Electricity consumed by coal storage sites and barges and in connection with the heating of oil supply lines. - Electricity consumed by fuel-handling facilities. - Electricity consumed by auxiliary steam boilers, including electric boilers, where the heat is not used for district heating. - Transmission losses up to the grid metering point. Own consumption does not include: - Electricity consumed by district-heating circulation pumps (with the purpose of pumping heat to heat consumers). - Electricity consumed by charge pumps and peak-load boilers. - Electricity consumed at building sites. - Electricity supplied to officials' residences. - Electricity supplied to third parties. Consumption not included in own consumption must carry its share of the PSO costs. In the electricity-generating facility (M1) metering must be performed after the necessary own consumption for electricity generation. Own consumption must be metered separately and with the same frequency that is stipulated for the recording of net generation if the installation makes it impossible to place the meter (M1) as described above. Consumption not included as own consumption must be metered separately if such consumption takes place before net generation (M1) is metered. 6.2.1 Negative net generation Own consumption during standstill can be perceived as negative net generation which means that the time series for net generation may contain positive and negative values. This is called the "net method". 23/55

The "net method" is not longer allowed. 6.3 Payment for metering performed Grid companies are responsible for ensuring that the correct metered data are obtained. The settlement meters must therefore be owned by the grid company which is also responsible for maintaining the meters. The costs in connection with settlement meters and their maintenance must in pursuance of current legislation be paid for by the owner of the electricitygenerating facility. The plant owner is obliged to provide the grid company with information about plant structure and an assessment as to where the meters should be placed. If it is necessary to convert the plant/meter system because of the introduction of new rules or the plant owner wants to switch to another type of settlement, the plant owner must pay the expenses in this connection. 6.4 Central power stations Within the framework of this regulation, the central power stations are defined as follows: - Enstedværket, unit 3 - Fynsværket, units 3 and 7 - Nordjyllandsværket, units 2+3 and the gas turbine - Skærbækværket, units 1 and 3 - Nordjyllandsværket, units 2+3 and the gas turbine - Enstedværket, unit 3 - Herningværket, unit 1 - H.C. Ørstedsværket, units 1, 4, 7 and 8 - Svanemølleværket, units 3 and 7 - Amagerværket, units 1, 2 and 3 - Asnæsværket, units 2, 4 and 5 (unit 4 will be unavailable from 2008 onwards) - Stigsnæsværket, units 1 and 2 (unit 1 will be unavailable from 2008 onwards) - Avedøreværket, units 1 and 2 - Kyndbyværket, units 21, 22, 41, 51 and 52 - Rønneværket, units 5 and 6 In principle, central power stations are subject to the same rules as other power stations. There are, however, some exceptions. Annex 4 outlines all the rules applying to central power stations. 6.5 Wind turbines Minimum requirements for the registration of net generation (M1): - Installed power 50 kw: 15/60 registration and remote reading - Installed power < 50 kw: Monthly or quarterly reading 24/55

The following also applies to installation-connected wind turbines: The time resolution requirement for the 'supply-to-grid' meter (M2) is the same as that for the consumption meter (M3). If the wind turbine uses net settlement, the requirements in terms of the frequency with which metering must be performed may change. The values for net generation (M1) must be sent to Energinet.dk. COLLECTIVE METERING OF WIND TURBINES If a group of wind turbines are metered collectively, they are considered a wind farm. Wind turbines can only use collectively metering if they are subject to uniform settlement rules. For a clarification of the concept 'uniform settlement rules', see Annex 6. The triviality limit as to when a wind turbine must use 15/60 registration is 50 kw. This limit also applies to wind farms, and in this connection the limit must be seen in relation to the wind farm's total installed power. Wind turbines which have been connected to the grid after 20 May 2003 must be metered separately and can therefore in pursuance of the Danish Executive Order no. 1365 of 15 December 2004 not form part of wind farms. 6.6 Other electricity-generating facilities Some definitions are required when dealing with other electricity-generating facilities. Electricity-generating unit An electricity-generating unit consists of one or several power stations supplying heat to the same collective heat supply grid and having the same owner at 1 January 2005. The definition is used for calculating the basic amount for local power stations operating on market terms, see Danish Executive Order no. 1367 of 15 December 2004. Power station A power station is one or several electricity-generating facilities located on the same plot of land or adjacent plots of land and having the same owner. This rule applies except in those cases when electricity-generating facilities in pursuance of this rule belong to the same power station but where they are settled in accordance with different rules. In those cases the result will be more power stations, one for each settlement method. Energinet.dk settles subsidies, etc., for each power station. Electricity-generating facility An electricity-generating facility is a generator connected to a power station. If a power station consists of several electricitygenerating facilities, these can be metered separately or collectively. Collective metering of electricity-generating facilities can only take place if they belong to the same power station and are settled in accordance with the same rules. Minimum requirements for the registration of net generation (M1): - Installed power 25 kw: 15/60 registration and remote reading 25/55

- Installed power < 25 kw: Monthly or quarterly reading The following also applies to installation-connected power stations: The time resolution requirement for the 'supply-to-grid' meter (M2) is the same as that for the consumption meter (M3). If the electricity-generating facility uses net settlement, the requirements in terms of the frequency with which metering is performed may change. The net generation value (M1) must be sent to Energinet.dk. Collective metering of electricity-generating facilities can only be effected if they belong to the same power station and are settled in accordance with the same rules. The triviality limit for 15/60 registrations is 25 kw. In connection with collective metering, this limit must be seen in relation to the power station's overall installed power. PV SYSTEMS WITH AN INSTALLED POWER 6 KW Such systems are not currently subject to any requirements for registration in the master data register for other electricity-generating facilities. The production from the PV system is therefore considered as negative consumption. In pursuance of this regulation, electricity generation need not be registered. MULTI-FUEL ELECTRICITY-GENERATING FACILITIES In connection with electricity-generating facilities using different types of fuel, of which some but not all are eligible for RE subsidies, the grid company (the metering point administrator) must submit a separate time series in addition to the total net generation from the electricity-generating facility (or power station), see section 10 of the Danish Executive Order on Master Data no. 1521 of 23 December 2004. This time series must include the share of the net generation attributable to the RE fuel used in the month concerned (RE electricity generation). The time series is a monthly time series submitted via Ediel. The deadlines for submitting monthly time series can be seen from section 4.5. If each of the RE fuels give rise to different settlement of subsidies, a RE time series for each settlement type must be submitted. 6.7 Autoproducers using net settlement Autoproducers using net settlement are divided into five categories, which are important for the necessary registrations. Gruppe 1: Gruppe 2: Gruppe 3: Gruppe 4: Facilities operating on market terms. Facilities subject to a purchase obligation. Multi-fuel electricity-generating facilities where only part of the generation is subject to a purchase obligation. Installation-connected wind turbines irrespective of size and installation-connected local plants with an installed capacity of less than 50 kw. 26/55

Gruppe 5: Installation-connected facilities irrespective of size where the surplus generation is zero or insignificant. For additional information about which generation facilities belong to which groups, see [1]. 6.7.1 Registrations to be performed by autoproducers using net settlement Autoproducers using net settlement are subject to the same metering requirements as apply to wind turbines and other electricity-generating facilities, see sections 6.5 and 6.6 with the following exceptions: GROUPS 1, 2 AND 3 Where facilities in groups 1, 2 and 3 are concerned, the principal metering points (M0, M1, M2 and M3) must be 15/60 registered irrespective of the size of the individual electricity-generating facility. For group 3 facilities, M1 must be divided into two 15/60 time series: M1a = net generation at facilities whose generation is subject to a purchase obligation. M1a = net generation at facilities whose generation is not subject to a purchase obligation. In addition to M1, the following must be submitted: For direct-connected facilities the consumption = the sum of M3 and M0 must be submitted to Energinet.dk. For installation-connected facilities, consumption M3 and electricity supply to grid (M2) must be submitted to Energinet.dk as individual time series. GROUP 4 For group 4 facilities, the metering for the electricity supply to grid (M2) must be submitted to Energinet.dk. The requirement regarding the frequency with which M2 must be metered is changed so that it is the same as that of M1. GROUPS 4 AND 5 Where facilities connected to the grid not later than on 31 December 2003 with an installed capacity < 25 kw are concerned, the generator may choose to calculate net generation (M1) in accordance with a fixed formula defined as: Installed capacity in kw x 2,200 hours, which for wind turbines are assumed to be spread out evenly over the year, Installed capacity in kw x 4,000 hours, which for other electricity-generating facilities are assumed to be spread out evenly over the year. For group 4 facilities, M2 must still as a minimum be quarterly registered. GROUP 5 In connection with net settlement of group 5, M2 is not required. The metering of the electricity supply from the collective electricity supply grid (M3) must be blocked to prevent the meter from reversing. 27/55

Kollektive elforsyningsnet M3 M2 Øvrigt forbrug M1 ~ Forbrugssted Egetforbrug til elproduktion [Captions] Kollektive elforsyningsnet = Collective electricity supply grid Øvrigt forbrug = Other consumption Forbrugssted = Consumption site Egetforbrug til elproduktion = Own consumption for electricity generation If in individual cases energy is actually supplied to the collective electricity supply grid, the volume is automatically used for covering the grid company's grid losses. The volume is therefore no longer available to the autoproducer. 6.8 Energinet.dk's estimates of 15/60 values An estimate of a 15/60 value is a calculation unit to replace metered 15/60 values for wind turbines and other electricity-generating facilities in those instances when net generation is not 15/60 registered and remote-read. Energinet.dk uses these estimates for computing the electricity generation and electricity consumption in the grid areas per quarter/hour in connection with fixing (see section 4.2) for use in connection with the continuous settlement of balancing power and the ordinary monthly settlement of the grid, system and PSO tariffs. Energinet.dk calculates estimates for the individual electricity-generating facilities not using 15/60 registration. The estimate is based on a 24-hour energy profile, which is calculated on the basis of a representative group of facilities using online metering. The profile is scaled so that it corresponds to that of an electricity-generating facility with an installed capacity of 1 kwh. A profile for wind turbines and a profile for other electricity-generating facilities are computed for each TSO area. The estimated 15/60 value of the individual electricity-generating facility is calculated as follows: Estimate in Western Denmark = ((electricity-generating facility's installed capacity)/4) * (profile's quarter-hourly value) 28/55

Estimate in Eastern Denmark = ((electricity-generating facility's installed capacity)/4) * (profile's quarter-hourly value) RESCALED ESTIMATE Energinet.dk rescales the calculated estimates when the monthly or quarterly readings have been submitted so that the total energy read in the month or quarter corresponds to the sum of the 15/60 values. The rescaled estimate is used in connection with plant settlement and Energinet.dk's correction settlement (see section 4.3). FAX-3-UNITS Fax-3-units are subject to special rescaling so that the total energy read in the three tariff periods corresponds to the sum of the quarter-hourly values in the three tariff periods. Fax-3-units are only found in Western Denmark. DISTRIBUTION OF ESTIMATED AND RESCALED METER VALUES BY ENERGINET.DK Energinet.dk distributes estimated 15/60 time series for the affected metering points via Ediel at 11:00 on the day after the day of operation to the grid companies (metering point administrators) so that they can be incorporated into the grid companies' continuous consumption forecasts etc. The rescaled 15/60 values are calculated on the basis of the fixing for the last day of the month and are distributed immediately afterwards. 29/55

7. Settlement metering - grid flow The following grid flow metering points must be metered: 1. Exchange with foreign countries (in 400 kv, 220 kv, 150 kv, 132 kv, 60 kv and 50 kv nodes connected to the foreign countries via interconnectors). 2. Exchange in 400/150 kv and 400/132 kv substations. As a main rule, it is metered on the 150 V or 132 kv side of the transformers 6. 3. Exchange in 150/60 kv, 150/10 kv, 132/50 kv, 132/30 kv or 132/10 kv substations, metered on the low-voltage side of the transformers. 4. Exchange with neighbouring grids to and from 60 kv or 50 kv grid areas if a separate 60/50 kv grid company services several local grid companies in a 60/50 kv region 7. 5. Exchange with neighbouring grids to and from local grid areas at 60 kv, 50 kv, 33 kv and 10 kv level. The metering point administrator summarises data from metering points associated with data categories 4 or 5 individually for each neighbouring grid area 8. This creates a 15/60 time series towards each neighbouring grid area where the grid company itself is responsible for performing metering. The time series are submitted to Energinet.dk, who computes the total sum for the flow into each grid area (summarised with a sign). A grid company cannot immediately compute this sum as some of the meters may be owned and/or administered by neighbouring grid companies. This means that an agreement must be made between neighbouring grid companies as to which of the parties is responsible for performing metering on the border between each exchange point. For determining the grid flow direction between two grid areas, the following rule applies: The recipient grid is always equal to the metered data collector's grid area. Positive energy is transmitted to the recipient grid. 6 All 400/132;400/150 kv transformer bays are equipped with energy meters for monitoring the reactive power balance (tgϕ) in the metering point. Exchange metering in the 400/132 kv and 400/150 kv substations is of value in grid analyses but are unimportant in terms of settlement as 400/132 kv and 400/150 kv grid losses are settled collectively (by Energinet.dk). 7 As far as the 50/60 kv grid is concerned, attention is drawn to the fact that if restructuring work is being implemented with a view to dividing the grid between local grid companies, it is also a requirement that new metering sites be established in order to comply with the metering requirements for data category 5 mentioned above. 8 In Eastern Denmark it is thus no longer allowed to summarise metering points in data category 3 before submission to Energinet.dk. These changes will be implemented in the course of 2007/2008 following an agreement between Energinet.dk and each grid owner. 30/55

Other exchange data are submitted to Energinet.dk as individual 15/60 time series. Data categories 1-3 comprise exchanges in one metering point. Exchanges are defined by means of two metered time series, one for the supply of electricity to the metering point and one for the electricity offtake from the metering point. Data category 3 can, for example, be described using the following series: - Electricity supplies to the 150 kv grid (data metered individually). - Electricity offtake from the 150 kv grid (data metered individually). 7.1 Metering on interconnectors between local grid areas All lines must be 15/60 registered and remote-read - including the lines that may connect neighbouring areas (eg 10 kv lines crossing the border between two grid companies) unless the two neighbouring grid companies guarantee that the extent of the exchange is financially insignificant. The affected grid companies are responsible for ensuring that significant exchanges are metered and re-distributed to Energinet.dk, who computes the grid company's total grid flow added. If the exchange on an interconnector does not form part of the 15/60 energy statement of the grid flow for two neighbouring grid areas, all Energinet.dk's statements will be prepared as if the interconnector does not exist. This also applies when settling public service obligations relating to the computed electricity consumption. The neighbouring grid companies' own eliminations, eg on the basis of annual registrations, are of no concern to Energinet.dk: No correction is performed. This exception applies provided the exchange does not take place between two local grid areas belonging to each their own 50/60 kv region (out of consideration for the hierarchically constructed grid pricing model). KNOWN EXAMPLES OF INTERCONNECTORS WITH CONSIDERABLE EXCHANGE - In some small corner of a grid company's geographical grid area it may historically have been most convenient to solely work with a permanent supply via a logon to the neighbouring grid company's grid. - An electricity-generating facility eg a wind turbine is located in the geographical grid area of one grid company but right beside the border to another grid company. The wind turbine feeds one line that solely (in which case it is a generator feeder) or predominantly supplies the electricitygenerating facility. However, the line crosses the border between the grid companies and feeds electricity direct into the grid of the neighbouring grid company. There are two and only two possible solutions to the problems described in the two examples: 31/55

Solution A: The grid flow in the interconnector is computed as a normal crossborder exchange 9. Solution B: The grid area is redefined for this particular purpose so that the electricity-generating facility/"enclave" and line as a whole are computed by the neighbouring grid company without any cross-border grid flow taking place in the locality. 9 The electricity-generating facility in example 2 is of course metered is the same manner as other electricity-generating facilities and is computed for the grid company to which the grid area belongs. In example 2 there will be situations when both figures (electricity generation and grid-flow contribution) are registered by the same meter. 32/55

8. Settlement metering - consumption In this section the rules for end-consumption metering in accordance with the retail market rules, see Regulations H1-H3, are described. 1. End consumption per metering point in the transmission grid. 2. End consumption per metering point in the regional grid. 3. End consumption per metering point in local grid areas. 8.1 End consumption in the transmission grid and regional grids End consumption drawn direct from the 132/150 kv grid must be 15/60 registered and remote-read in order for this consumption to be isolated from the grid loss in the transmission grid. All end consumption per metering point in regional grid areas, ie all end consumption that is not attributable to grid losses, must be 15/60 registered and remote-read in order for this consumption to be isolated from grid losses. For settlement purposes, end consumption is transferred to one of the underlying local grid companies. This means that the company which has assumed a supply obligation towards the local grid company also has a supply obligation for this end consumption. The transfer is effected by considering the consumption as being grid flow flowing out of the grid area and into the grid area of the local grid company. CENTRAL POWER STATION SITES The preparation of consumption statements at power station sites is described in Annex 4 BANEDANMARK IN WESTERN DENMARK From 1 January 2000, Banedanmark will be considered a special end consumer in accordance with the terminology used in this regulation, and Banedanmark's total area consumption - and thus end consumption - is computed in the normal manner by Energinet.dk on the basis of the total time series for exchanges which collectively define Banedanmark's grid area. Any supplies of braking energy to Banedanmark are thus a normal part of the exchange of total time series with neighbouring grids, in this case the 150 kv transmission grid. BANEDANMARK IN EASTERN DENMARK In Eastern Denmark, Banedanmark is an ordinary consumer in the grid area. Any supplies of braking energy to Banedanmark are registered as negative consumption. 8.2 End consumption in local grid areas From 1 January 2005, all end consumption per metering point with an annual consumption >100,000 kwh must be 15/60 registered and remote-read, see Regulation H2. The requirement applies to end consumption in local grid areas. 33/55

Local grid companies must after each day of operation submit a time series for meter consumption for each BRP for consumption using 15/60 registration to Energinet.dk via Ediel, see section 4.1. The time series contain the aggregated time series for 15/60 registered end consumption for each metering point attributable to the individual BRPs for consumption. End consumption of consumers using profile settlement: End consumption below the mandatory limit where the owner has not voluntarily chosen to use 15/60 registration need not be submitted to Energinet.dk. End consumption below the mandatory limit is settled in accordance with the retail market rules through the submission of proportional figures, a statement of the residual consumption and the final settlement of customer accounts, see Regulations H1- H3. 8.3 End consumption at production sites At a production site there will also be consumption. This consumption must also bear its part of the PSO costs and must therefore be metered. The end consumption at production sites consists of (see the diagrams in section 6.1): - For a customer with a direct-connected facility, the consumption is the sum of the values metered at M3 and M0. - For a customer with an installation-connected facility, the consumption must be computed as M3 + M1 - M2. M0 and M3 are considered normal end consumption and must be metered in accordance with the rules concerning end consumption. This means that they must be 15/60 registered and remote-read if consumption exceeds the mandatory limit. When consumption is 15/60 registered, metered data must form part of the time series for metered consumption; otherwise the consumption is by definition included in the residual consumption. Where PV systems with an installed capacity of 6 kw are concerned, generation is considered negative consumption (see section 6.6). In this way, the consumption metering for such a facility may become negative. END CONSUMPTION AT PRODUCTION SITES USING NET SETTLEMENT The rules have been made stricter for autoproducers in groups 1-3 using net settlement, irrespective of the size of the consumption. The consumption of these facilities must always be 15/60 registered and remote-read. For autoproducers in groups 4 and 5 using net settlement the size of the consumption still determines the frequency with which consumption metering is performed. The consumption which is to form part of the time series for metered consumption or the calculation of proportional figures must be computed differently for the various groups of autoproducers using net settlement. 34/55

For groups 1-3 a net assessment is prepared over the hour so that for an hour electricity can only be drawn from or supplied to the grid. This is called net delivery from grid and net delivery to grid, respectively. Group 1: Gross consumption must be included Gross consumption = own generation + net delivery from grid Own generation = net generation - net delivery to grid Group 2: Net delivery from grid must be included Group 3: As is the case with group 1, gross consumption must be included Groups 4 and 5: For these two groups, the consumption metering (M3) must be included. 8.4 Changed time resolution for metered end consumption in Western Denmark from 1 April 2008 In order to maintain the security of supply and thus keep up system operation Western Denmark is forced to uphold the requirement that quarter-hourly registration must be used on the production side. Where Energinet.dk's statement of electricity consumption is concerned, a parallel consideration at an aggregate level must be taken into account. This means that quarter-hourly grid-flow registration will still be required in Western Denmark. There are, however, no similar requirements for end consumption metering, and following requests from several grid companies and commercial players the requirements in terms of time resolution for metered end consumption will be harmonised so that they correspond to those governing hourly registration. In order to give grid companies and the commercial players proper notice and for the sake of Energinet.dk's current task portfolio, the switch from using quarter-hourly registration to using hourly registration of metered end consumption in Western Denmark will be effected from 1 April 2008. The rules governing this and the ensuing consistency corrections in Regulation D1 and other relevant regulations will be presented at a later date in good time before 1 April 2008. 35/55

9. Basic definition of electricity consumption The introduction of net settlement for autoproducers has made it necessary to operate with different definitions of electricity consumption for various settlement purposes. In this section the fundamental statements of electricity consumption are defined. Section 10 describes how the statement of the electricity consumption for the various types of settlement is computed. Energinet.dk computes the electricity consumption centrally as this ensures that the computation is made in the same way and at the same time in all of Denmark. This ensures consistent settlement. 9.1 Definition of the electricity consumption in a grid area per hour and month 9.1.1 Exchange with neighbouring grid areas Exchange with neighbouring grid areas are computed with signs: Exchange = + grid flow into the grid area grid flow out of the grid area 9.1.2 Computation of grid area consumption The electricity consumption of a grid area is calculated quarter-hourly in Western Denmark and hourly in Eastern Denmark in accordance with the following equation: Grid area consumption = end consumption + grid losses = exchange with neighbouring grid areas + net generation. Consumption cannot be computed with the degree of detail required by the Nordic market model if all consumption sites solely use direct metering. As a main rule, the electricity consumption is instead computed by performing metering on the interconnectors to grid areas. The gross electricity consumption in a grid area thus equals: + grid flow into the grid area grid flow out of the grid area + net generation supplied direct into the grid area. All consumption is administered by a BRP with the exception of that consumption which takes place at consumption sites with electricity-generating facilities using net settlement. The computation of the grid area consumption includes the consumption for which balance responsibility has been assumed. Grid losses are treated in the same manner as the normal end consumption. This means, for example, that grid losses must bear the proportionate share of the PSO costs. 36/55

9.1.3 Residual consumption The residual consumption is used for calculating the electricity consumption of the individual BRP for consumption. In the retail market the residual consumption is also used for computing the electricity consumption for each electricity supplier, see Regulations H1-H3. The electricity consumption can be split up even further: Grid area consumption = end consumption + grid losses = 15/60 registered end consumption + other end consumption + grid losses The residual electricity consumption is defined as: Residual consumption = other end consumption + grid losses = Grid area consumption 15/60 registered end consumption. 9.1.4 Computation of electricity consumption for each BRP for consumption for the settlement of balancing power For a BRP for consumption the hourly electricity consumption in local grid areas is computed in accordance with the following equation: Stated electricity consumption to be used in connection with the settlement of balancing power by a BRP for consumption = Metered time series for consumption + distributed consumption. Distributed consumption = Residual consumption * share quotient In regional grid areas, the transmission grid area and for Banedanmark in Western Denmark the grid area consumption (see section 9.1.2) is equal to the grid losses in the grid area. In these grid areas the stated electricity consumption is thus only attributed to one single BRP for consumption. 9.2 Rounding-off and units The electricity consumption in a grid area for a given period is calculated in MWh to six decimals. 37/55

10. Settlement basis per grid area Energinet.dk performs various types of settlement involving various statements of the electricity consumption and the electricity generation: - Settlement of electricity offtake (grid and system tariffs). - Settlement of production infeed (grid tariff). - Settlement of public service obligations (PSO tariff). - Settlement of balancing power and power imbalances with BRPs. In addition, Energinet.dk settles subsidies etc. for electricity-generating facilities on the basis of the electricity generation recorded. In the following the main principles of these settlement types are described. Balance responsibility is defined in Regulation A, while the related settlement is described in Regulation C2. The management and settlement of end consumption at central power station sites are described in Annex 4. 10.1 Settlement of electricity offtake (grid and system tariffs) Grid pricing is structured hierarchically seen from the end consumers' point of view. The end consumer must pay Energinet.dk's grid tariff + grid tariff for the regional grid + grid tariff for the local grid. In some places the two latter grids are not split up and therefore there will only be one grid tariff. When a grid company must collect its own grid tariff from another grid company, this must be based on the energy statement prepared by Energinet.dk. The basis of Energinet.dk's grid and system tariffs is the same and is therefore described collectively in the following section. Energinet.dk settles the grid and system tariff with the individual grid companies for the electricity offtake from this grid. For grid companies with regional grids payments are only collected for the grid losses as end consumers physically drawing electricity from a regional grid will for settlement purposes be transferred to a local grid. If a local grid is used by several regional areas and at least of one the areas belongs to a regional grid company, the consumption which forms the basis of grid pricing must be computed in the various regional areas. This is necessary by way of preparing the basis for the regional grid company's collection of grid tariffs from the local grid company. 10.1.1 Statement of the electricity offtake in a grid area WITHOUT AUTOPRODUCERS USING NET SETTLEMENT The energy settled equals the grid area consumption, which was defined in section 9.1.2. 38/55

WITH AUTOPRODUCERS USING NET SETTLEMENT The grid area consumption is the consumption that is administered by a BRP for consumption. For autoproducers in groups 2, 4 and 5 using net settlement this consumption is equivalent to the consumption which is subject to the payment of grid and system tariffs. For autoproducers in groups 1 and 3 using net settlement, own production must be deducted. Electricity offtake = Grid area consumption own production (groups 1 and 3) A net assessment over the hour is prepared so that in one hour electricity can only be drawn from or delivered to the grid. This is called net delivery from grid and net delivery to grid, respectively. Own production = Net generation (M1) net delivery to grid (M2). 10.2 Settlement of production infeed (grid tariff) All electricity generators must pay for gaining access to the transmission grid irrespective of where the physical connection point is located in the grid. The grid tariff is related to the net generation. Local facilities and wind turbines that are under a purchase obligation as stipulated in section 59(a) of the Danish Electricity Supply Act are exempt from paying the grid tariff. The grid tariff is collected from the BRP for production. For wind turbines on market terms for which Energinet.dk is the BRP, the grid tariff is collected from the grid company, see section 3.3, however. 10.2.1 Computation of production infeed for a BRP for production WITHOUT AUTOPRODUCERS USING NET SETTLEMENT The energy settled equals the sum of the net generation from electricitygenerating facilities with the exception of electricity-generating facilities under a purchase obligation, see section 59(a) of the Danish Electricity Supply Act. WITH AUTOPRODUCERS USING NET SETTLEMENT Electricity-generation facilities not using net settlement are included as described above. Electricity-generating facilities using net settlement contribute as follows: Group 1: Net delivery to grid Group 2: These facilities are always under a purchase obligation and are therefore not included. Group 3: Share of electricity not under a purchase obligation delivered to the grid. Group 4: Delivery to grid (M2) unless the facility is under a purchase obligation. Group 5: These facilities are not included as they by definition never supply electricity to the grid. 39/55

10.3 Settlement of public service obligations (PSO tariff) The PSO costs must be distributed evenly on all electricity consumption. As a main rule, Energinet.dk sets up direct settlement routines with all regional and local grid companies and end customers connected to the transmission grid (special grid areas) with a view to collecting the PSO tariff. 10.3.1 Computation of the energy basis for the PSO tariff for a grid area WITHOUT AUTOPRODUCERS USING NET SETTLEMENT The energy settled equals the grid area consumption, which was defined in section 9.1.2. WITH AUTOPRODUCERS USING NET SETTLEMENT For autoproducers using net settlement two energy statements are prepared. Two statements are required as different tariffs are used in the calculation of the actual payment. At first, the PSO tariff is charged on all consumption in the grid area, and then a PSO discount for the autogeneration in the grid area is calculated. The energy basis for the PSO tariff equals the grid area consumption + own generation of autogenerators using net settlement in groups 2, 4 and 5. The energy basis for the PSO discount equals the own generation of all groups using net settlement. Own generation is calculated differently in the various groups of autoproducers using net settlement: Groups 1, 2 and 3: A net assessment over the hour is prepared so that in one hour electricity can only be drawn from or delivered to the grid. This is called net delivery from grid and net delivery to grid, respectively. Own generation = Net generation (M1) Net delivery to grid. Group 4: Own production = Net generation (M1) Gross delivery to grid (M2). Group 5: Own production = Net generation (M1). 10.4 Settlement of balancing power with BRPs The data basis for the ordinary settlement is computed continuously for 24 hours at a time. The data basis of the balance settlement consists of the fixed data set, see section 4.2. 10.4.1 Computation of balancing power for BRPs for consumption Balance responsibility for consumption comprises: - 15/60 registered end consumption per metering point, and/or - end consumption at production sites and/or - distributed consumption per grid area, and/or - electricity consumption in the transmission grid, regional grids and special grid areas. 40/55

The division of the grid geography mentioned above makes it possible to identify the electricity consumption, and Energinet.dk uses this information when settling the BRPs, comparing it to the daily submitted notification (see Regulation C1). Where end consumption at central power station sites is concerned, special rules apply to the way in which the balance responsibility for consumption is managed, see Annex 4. 10.4.2 Computation of balancing power for BRPs for production Energinet.dk settles imbalances on the basis of the recorded total net generation attributable to the BRP. For each player the following is settled: Net generation compared to the daily submitted notification (see Regulation C1). For West Danish players an additional balance settlement - called power imbalance settlement - is prepared: Net generation compared to the daily submitted notification (see Regulation C2) 10. The two types of settlement are prepared in such a way that the player does not pay twice for the same imbalance. 10.5 Settlement of subsidies etc. for electricity generation Subsidies are calculated on the basis of the electricity generation recorded and in accordance with current legislation, see Regulation E 11. 10.6 Data basis for ordinary settlement and correction settlement The computations for the ordinary balance settlement are prepared for 24 hours at a time, see section 4.2. The data basis used for these computations must be reproduced precisely in the energy statements constituting the basis for the monthly settlement of the grid, system and PSO tariffs. This means that in connection with the ordinary settlement the metering faults which occur during the month (ie metering faults discovered after fixing) are thus not taken into account. Monthly and quarterly values will give rise to the rescaling of estimates after the end of the month and quarter. The estimates will be included in the ordinary settlement. Corrections and rescaled values will form part of the ordinary correction settlement. 10 Energinet.dk's Regulation C2 has not yet become effective. Until it becomes effective, reference is made to "Krav til produktionsbalanceansvarlige aktører fra den 1. januar 2005" (Requirements for BRPs for production from 1 January 2005, Memorandum ELT2004-109, version 5, November 2004. 11 Energinet.dk's Regulation E has not yet become effective.

Annex 1: Metering of local production with displaced settlement point This annex specifies the meter values for local production with displaced settlement point to be submitted to Energinet.dk. Displaced settlement point for local CHP plants and wind turbines Where local CHP plants are concerned, metering site and settlement point are located at the point where the plant is actually connected to the collective electricity supply grid. This point is thus of decisive importance when it comes to determining the size of the payment to the plant owner. The physical connection point is determined by the grid company on the basis of the technical and financial conditions. The settlement point is defined as the first point it has in common with the collective electricity supply grid. 12. The problems are different where wind turbines are concerned. Here, the payment is stipulated by legislation without any settlement point being defined. As losses are significant, grid companies have introduced a joint stipulation regarding the settlement point of wind turbines 13. If for practical or financial reasons it is not expedient to place the settlement meter in the correct settlement point (eg because low-voltage metering would be cheaper), an agreement can be made in both situations to place the meter somewhere else. In this case, losses must be calculated up to the correct settlement point, and the generation recorded must be corrected accordingly before the metering point administrator resubmits meter data to Energinet.dk, see section 4.1. - Where wind turbines with displaced settlement point are concerned, the generation metered is always corrected by 1%. 13 - Where local CHP plants with displaced settlement point are concerned, the correction can be calculated in accordance with the Danish Energy Association's guidelines on the calculation of transmission and transformer losses. The use of a displaced settlement point is thus to be seen as an offer, and if the method is used by a local generator, generation must be corrected by the chosen loss correction factor. 12 In cases when a generator transformer is installed in the vicinity of the plant, care must be taken where ownership is concerned. Normally, the generator transformer will be the property of the plant owner, and grid losses etc. will therefore affect the plant owner. Occasionally, the grid companies offer the plant owner to build and maintain the generator transformer. If ownership passes to the grid company, the transformer will then become part of the public grid. The connection point is therefore moved to the low-voltage side of the generator transformer. 13 See ELFOR memorandum ED96-009b: "Fællesbestemmelse for vindmøllers afregningspunkt" (Joint stipulation regarding the settlement point of wind turbines). 44/55

What are meter values used for? The meter values from local electricity-generating facilities are used for three purposes: 1. for computing the electricity consumption in the grid area to which the wind turbine or plant is connected, 2. for settling the plant owner if the plant is under a purchase obligation or receives subsidies, and 3. for statistical purposes. The rule is that for the three purposes one and only one set of figures must be used, corresponding to the time series for net generation where the individual meter values are corrected by the chosen loss correction factor. As such, the report is faulty if a metering point administrator submits time series for net generation from a local plant or a wind turbine with a displaced settlement point based on the actual meter reading. 45/55

Annex 2: The latest point in time after the day of operation when metered data must have been received by Energinet.dk The time: "Not later than at 10:00 on the third working day after the day of operation" is interpreted as follows: Day of operation Monday Tuesday Wednesday Thursday Friday Saturday Sunday 10:00 on the third working day after the day of operation Thursday Friday Monday Tuesday Wednesday Wednesday Wednesday DAYS THAT ARE NOT CONSIDERED WORKING DAYS: - Weekends (Saturday and Sunday). - New Year's Day, Maundy Thursday, Good Friday, Easter Monday, fourth Friday after Easter, Ascension Day + the day after Ascension Day, - Whit Monday, Christmas Day and Boxing Day. - 24. December, 31 December, Constitution Day. At www.energinet.dk a calendar is found specifically outlining which days are working days. 46/55

Annex 3: Standard fault report Each time time series with corrected values following ordinary fixing are submitted at 10:00 on the fifth working day after the day of operation, the form must be filled in and sent to Afregningskontoret (Settlement Office), see section 4.1: E-mail: Afregning@Energinet.dk. Ediel no. : Name of plant/time series: Re-submitted in the following period Start time (YYYY-MM-DD HH:MM): End time (YYYY-MM-DD HH:MM): Original energy volume (kwh): New energy volume (kwh): Difference (kwh): Re-submission time (YYYY-MM-DD HH:MM): Explanation : All fields in the report must be filled in, including the explanatory field, which Energinet.dk uses for preparing fault type statistics. Start and end times must lie within the same month. If the correction encompasses a period stretching over several months, one form must be filled in for each of the months concerned. The original energy volume must always be filled in with the fixed value. This means that even if the time series is corrected several times, the original energy volume will remain the same until re-fixing takes place. 47/55

Annex 4: Managing metering tasks and consumption at central power stations Central power stations are stations which for historical reasons are managed a little differently than ordinary power stations. An exhaustive list of central power stations can be seen in section 6.4. All ordinary consumption at the power station, which is connected direct to the local grid company's grid without being connected in any way to the power station's internal grid, is not included in the power station's consumption. As such, the metering point concerned is in al respects treated as an ordinary metering point by the grid company in question irrespective of whether the customer is the plant owner or a third party. These metered data are subject to the common rules for consumption and must not form part of the computations described in this annex. RESPONSIBILITY FOR METERING The responsibility for carrying out metering tasks at a central power station site rests with the local grid company or transmission company in whose grid area the power station site is located. If this is not clear, the responsibility for metering is decided between the affected grid companies and Energinet.dk. METERED DATA TO BE OBTAINED All metered data must be 15/60 registered. All exchange with the collective electricity supply grid must be metered. Metered data making it possible to compute the generation for each power station unit must be obtained. Consumption that is not own consumption for electricity generation must be metered. Own consumption for electricity generation is defined in section 6.2. Where own consumption is concerned, there are two options: Own consumption is either metered separately or the generation meter is placed in such a way that own consumption is deducted from the generation. If the last option is used, own consumption must also be metered during standstill. Own consumption during standstill is treated as ordinary consumption. External own consumption is own consumption for electricity and CHP generation, eg pumps placed outside the plot of land concerned - possibly many kilometres away. This is included as own consumption at the power station, ie the metered data concerned is on paper considered as covering the supply of electricity to the power station's internal electricity grid. This must also be metered. EXCHANGE All metered data exchanged with the transmission grid must be submitted to Energinet.dk as individual time series. 48/55

GENERATION All metered data concerning generation must be aggregated in such a way that it is possible to compute the generation for each individual unit. If own consumption (inclusive of external own consumption) is metered separately, it must be deducted from the generation time series. The time series must, however, not be negative (see section 6.2.1). If own consumption exceeds generation, the generation time series must be set to 0 and the negative value must be included in the time series 'own consumption during standstill'. Legitimate recipients of generation time series are Energinet.dk, the plant owner, the BRP for production and the electricity supplier (generation). END CONSUMPTION There are two ways of computing a power station site's ordinary consumption and own consumption during standstill: 1. Consumption can be changed, so that on paper it is connected direct to the local grid company's grid. In this case, consumption is in all respects treated as ordinary consumption by the grid company, with the grid company being responsible for collecting the PSO, grid and system tariffs. In this case the grid company decides whether the consumption can be split up on several BRPs. 2. Energinet.dk assumes the balance responsibility, while the PSO, grid and system tariffs are collected direct from the customer. In this instance, all end consumption must be attributable to the same BRP. If a party wants to change BRP, Energinet.dk must be notified of this with one month's notice in accordance with the normal rules for changing BRP for consumption. If method 1 is to be used, the consumption must be included in the local grid company's ordinary consumption statements. The consumption must also be included in the exchange between the grid from which electricity is actually drawn and the local grid company. If method 2 is used, own consumption during standstill is aggregated into one time series, while the consumption not constituting own consumption for electricity generation, is aggregated into one time series. Legitimate recipients of these time series are Energinet.dk, the plant owner, the BRP for consumption and the electricity supplier (consumption). The rules described in this annex will give rise to some changes. These changes will be implemented in the course of 2007/2008 in connection with a review of the conditions at all central power stations performed in cooperation with the generator and the metered data collectors. 49/55

Annex 5: Information about electricity consumption for various settlement purposes via Ediel In Annex 5, a general overview is given of the information about the electricity consumption in the grid areas which Energinet.dk forwards to grid companies and BRPs per Ediel. BRPs for consumption - Consumption schedule - Adjusted consumption schedule - Possible trading schedules - Overall fixed consumption - Metered end consumption in grid areas - Distributed consumption in grid areas - Fixed and re-fixed residual consumption in grid areas - Real-time power market: Prices for upward and downward regulation and Nord Pool's area price BRPs for production - Generation schedules divided into the following categories: Central generation, local generation and wind power generation - Adjusted generation schedule - Total regulating power schedule - Total generation schedule - Power schedules divided into the following categories: Central generation, local generation and wind power generation - Fixed generation divided on the following categories: central generation, local generation, wind power generation and overall generation - Fixed generation in the individual grid areas divided into the categories central generation, local generation and wind power generation - Real-time market: Prices for upward and downward regulation - Load-frequency controller: Prices for upward and downward regulation - Regulating-power price for a BRP - Resulting price for the settlement of power imbalances - Grid tariff for generation (price) - Deduction of grid tariff for generation for autoproducers using net settlement Grid companies - Fixed sum of central and local generation - Fixed sum of wind power generation - Fixed sum of exchanges - Fixed grid area consumption - Sum of submitted, fixed and metered consumption for each BRP for consumption - Fixed metered consumption per BRP for consumption - Fixed and re-fixed residual consumption - Real-time power market: Prices for upward and downward regulation and Nord Pool's area price - Estimated and rescaled quarter-hourly values for monthly or quarterly read electricity-generating facilities 50/55

If the grid area includes autoproducers using net settlement: - Total consumption (subject to the payment of grid tariff) - Overall consumption (subject to the payment of PSO tariff) - PSO discount, energy - Consumption of autoproducers using net settlement (subject to the payment of grid tariff) - Consumption of autoproducers using net settlement (subject to the payment of PSO tariff). 51/55

Annex 6: Rules for collective metering of wind farms Uniform settlement rules are understood as: (General exception from the rules outlined below: If different types of settlement power has been redeemed for the individual wind turbines in a wind farm in the form of scrap certificates, the turbines are considered as being subject to different settlement rules, and collective metering is therefore not allowed). Wind turbines whose generation is subject to a purchase obligation: - Settlement of "existing" wind turbines in pursuance of section 56(a)(2) of the Danish Electricity Supply Act, or - Settlement of "existing" onshore wind turbines in pursuance of section 56(a)(6) of the Danish Electricity Supply Act, or - Settlement of "other" offshore wind turbines in pursuance of section 56(a)(6)(2) of the Danish Electricity Supply Act, or - Settlement of installation-connected wind turbines 25 kw in pursuance of section 56(b) of the Danish Electricity Supply Act. Utility-financed wind turbines: - Settlement of utility-financed wind turbines in pursuance of section 56(2) of the Danish Electricity Supply Act, or - Settlement of utility-financed wind turbines in pursuance of section 56(c)(2) of the Danish Electricity Supply Act, or - Settlement of utility-financed wind turbines in pursuance of section 56(c)(3) of the Danish Electricity Supply Act, or Wind turbines settled on market terms: General rule: All wind turbines in the collectively metered wind farm must use the same BRP for production. - Settlement of wind turbines on market terms in pursuance of section 56 of the Danish Electricity Supply Act, or - Settlement of wind turbines (ailing) on market terms in pursuance of section 56(5) of the Danish Electricity Supply Act. 52/55

Annex 7: Quality code for time series (Ediel message) This annex describes the quality codes which must be used in connection with Ediel time series containing 15/60 values. If a time series has been classified as "preliminary values", it must be resubmitted prior to fixing at 10:00 on the fifth working day after the day of operation to all legitimate recipients with all values being categorised as "final values". It is thus not a requirement that estimates be distributed as "preliminary values". If the time series has been checked, and faults and defects have been corrected and remedied in accordance with the procedure outlined in section 4.1.1, it can be submitted with all values being categorised as "final values". All values in Ediel messages are assigned a status code. The following codes can be used: - Z03: Preliminary value, no value (value = 0) - Z02: Preliminary value, estimated (replacement value) - 99: Final value, estimate - 136: Final value, metered Z03 is used if values are missing but only until the third working day. Z02 can be used if the grid company uses replacement values in the time series and only until fixing. 99 is used in cases where correct metered values can never be obtained. 136 is used for normal metered values. When submitting values coded Z02 or Z03, the grid company must subsequently re-submit the time series using codes 99 or 136 prior to fixing. It is not a requirement that code 99 be used. All checked values can be submitted using code 136. 53/55

Annex 8: Force majeure in connection with ordinary fixing Situations resulting in the fixing being postponed In certain situations Energinet.dk reserves the right to postpone the ordinary fixing and thus the balance settlement for a specific day of operation. The incidents which may postpone the fixing include: 1) Technical disturbances or other incidents at Energinet.dk which make it impossible to implement the necessary computations at the ordinary fixing time at 10:00 on the fifth working day after the day of operation. 2) Technical disturbances or other problems at one or several grid companies resulting in meter data from all metering points in one or several grid areas not being submitted to Energinet.dk. 3) Missing meter data, typically data obtained from exchange metering, resulting in serious faults in the residual consumption profile for one or several grid companies. 1) Irregularities at Energinet.dk Energinet.dk aims at limiting outage time in connection with faults in operating equipment, software, etc. as much as possible. Similarly, Energinet.dk endeavours to plan the rearrangement and upgrading of operating equipment and software in a manner that limits outage time as much as possible. 2) Irregularities at the grid company Likewise, the grid company should aim at limiting outage time etc. as much as possible. 3) Missing meter data It would be highly disadvantageous for the grid companies if the fixed data basis for a given day of operation results in a very distorted residual consumption profile. Energinet.dk will postpone the fixing if the residual consumption in one or several grid companies is severely distorted, eg an incorrect sign has been assigned to the consumption or the consumption has been set to zero for a few hours or the entire 24-hour period. Situations not resulting in the ordinary fixing being postponed A few missing time series for end-user consumption metered on an hourly basis for a given grid area will normally not distort the residual consumption profile to 54/55

any significant extent, but the energy distribution between the metered end consumption and residual consumption may become abnormal. Missing exchange time series may dramatically distort the residual consumption. This will not necessarily be the case when time series for electricitygenerating facilities are missing. The most important parameter in connection with the decision to postpone the fixing is the appearance of the residual consumption profile but not necessarily the energy content. Information about the postponement of fixing If re-fixing is postponed, information about this will be available at Energinet.dk's website no later than at the time when re-fixing normally takes place. If a grid company encounters sudden problems as mentioned under pt. 2) or is planning to rearrange or upgrade operating equipment and software which will result in outage time at a later stage, Energinet.dk must be informed hereof as soon as possible. This allows Energinet.dk to continuously provide information about current delays from day to day or expected delays at a later stage. 55/55
