2 Vision and mission Vision KE aims to be the leading utility company in Denmark Mission KE supply customers with Water, District Heating & Cooling, Sewer & Town Gas KE ensures efficient supply of high quality to the lowest possible price KE improves the city environment 2

3 Copenhagen Energy in numbers 1 million water consumers ½ million sewer consumers ½ million district heating consumers 150,000 town gas consumers 725 employees 700 million USD $ turnover Annual investments in pipes Nearly 175 million USD $ 3

6 District Historyheating has for many years been part of the infrastructure in Copenhagen 1925: - First district heating from Gothersgade Power Station 1932: - Steam supply from HCV to the western part of Copenhagen. During the thirties the supply of steam was expanded to cover central Copenhagen 1953: - SMV was established with supplies of both steam and hot water for the northern part of Copenhagen. The capacity made it possible to expand the supply to cover half of Copenhagen 1971: - AMV was established 1992: - Obligation to connect to district heating (target: 97% of all households) 2010: - >98 % of all households in Copenhagen heated by district heating 6

8 Key figures KE operates 2 networks: 98% of Heat market is covered by District Heating km, GWh/year and costumers (typical apartment blocks, building blocks and one family houses) The distribution network is nearly completed Turnover approx. 425 mill. $US., approx. 30% as steam The KE network is supplied from: CTR (DH Water) Dong Energy / Vattenfall (Steam/heat) Own peak load stations District Cooling

14 Load dispatch in the Copenhagen DH system Københavns Energi A/S

15 Heat Load Duration Curve 100% Peak load boilers: 10% 60% Base load level 2: 20% 30% Base load level 1: 70% 0% Time, hours 15

16 Benefits for the consumers and for society Possibilities of using low value energy sources as: - Surplus heat from Combined Heat and Power - Industrial waste heat - Waste incineration - Biomass and other renewable sources Controlled emissions and reduced environmental pollution (few chimneys with filters instead of a large number of small local chimneys) Flexible choice of fuel - heat sources can easily be adjusted to actual energy prices. High reliability of heat supply to the costumers with high level of comfort Competitiveness: cheaper than individual heat supply 98% households supplied by district heating results in a CO 2 - reduction of ton from 1990 to 2005 equal to a reduction of approximate 20% of the amount of CO 2 - discharge in Copenhagen

17 Framework Regulation Heat act Non profit principle. Price notify to the price committee (Energitilsynet) (no approval) Primary heat supplier is CTR Owned by Copenhagen and 4 surrounding municipalities CTR buy heat from DONG, Vattenfall, Amagerforbrænding (Waste Incineration), Vestforbrænding (Waste Incineration) and a number of peak load plants Copenhagen Energy takes app. 70% of CTR s heat supply Steam is coming from DONG Energy Vattenfall (from January 2009) Own peak load boilers Professional co-operations Danish DH association Euroheat & Power The 6 town co-operation Danish Board of District Heating Københavns Energi A/S

18 Heat law and tariffs The basic principles in Denmark: Non profit tariffs Cost-reflecting tariffs Split of costs between heat and electricity (CHP) Energy regulator Based on long term budgets

19 None profit tariffs What dos non profit mean? Costs include: Fuel Salaries Operational costs Interest Depreciation

20 Cost reflecting tariff structure Often 3 elements in the tariff: 1. Meter tariff: - financial cost of meters - O&M cost of meters - Calibration of meters 2. Fixed tariff - financial costs of all investments - salaries for staff - heat loss (fuel for) 3. Variable tariff - cost of fuel - electricity for boilers, pumps etc - water

21 Price Committee The prices must be calculated in accordance with the Heat Law (non profit), and the DH company is responsible for following the law, but: Energy regulator is to be informed about prices every time they are changed Prices are normally not approved by the Energy regulator, but it is possible to get a pre-evaluation Complaints from consumers and others are tried by the Energy regulator Complains tried by the Price Committee can be appealed to the Energy Board of Appeal Finally it can be tried at the private court system

22 CHP Tariffs Electricity price A: All costs paid by the power side B: Technology for separate power production Possible electricity prices Contract zone C: Technology for separate heat production Possible heat prices Heat price D: All costs paid by the heat side

23 Copenhagen Heat Price USD $/year/one family house (KE: 2009) compared with average (2008). House 130 m2 18,1 MWh/Year Thousands of DDK KE KE A/S Simple Average Weighted average Oil Natural gas

24 System Optimization at all levels Detailed design of network Daily operation of network Load dispatch Long term planning of production Maintenance Systematic Route planning

25 The tunnel AMV/AMF and the tunnel Lower production costs The supply is secured in the future Flexibility during the conversion Less pollution 25

26 New DH tunnel under Copenhagen Budget: 150 million USD $ Length: 2.5 miles Diameter: 14.0 ft 3 access shafts depth: ft Tunnel both for hot water and steam Project completed in 2009

27 Largest construction project in Copenhagen since the Metro (subway) Københavns Energi A/S

28 Conditions Conversion from steam to water Heat loss from network: 16% -> 7% O&M reduced from 12 USD $./ft/year to 1 USD $./ft/year Hot water can be produced appr. 2.5 USD $./GJ cheaper than steam Reduced loss of water (condensate) The project is completed in 2025 Rate of interest (NPV) 4,5 % p.a. Value off CO2 reduction not included Reference Reconstruction of condensate pipes 28

31 Heat Sources for District Heating Systems Base load units: Co-generation units Solid waste incineration plants Plants for utilisation of industrial waste heat Heat-only boilers for solid fuel High construction cost Low primary fuel cost Substantial environmental impact before cleaning Poor modulation ability Require substantial start-up time Peak load units: Light oil fired heat-only boilers Natural gas fired heat-only boilers Low construction cost High primary fuel cost Moderate environmental impact Good modulation ability Limited requirements in respect of start-up time 31
