4 1 Introduction RULE REQUIREMENT Clause Publication of information about tariffs and tariff classes (a) A Distribution Network Service Provider must maintain on its website: (3) a statement of expected price trends (to be updated for each regulatory year) giving an indication of how the Distribution Network Service Provider expects prices to change over the regulatory control period and the reasons for the expected price changes. This document is Energex s Statement of Expected Price Trends for 2014/15. It has been prepared for the final year of Energex s regulatory control period in accordance with Clause (a)(3) of the National Electricity Rules (the Rules). The NER limits the requirement to provide indicative price trends beyond the current regulatory control period, which ends 30 June When developing tariffs and charges, Energex has considered customers changing expectations and the current upwards pressure being exerted on energy prices. Energex is committed to ensuring a balanced commercial outcome while meeting customer requirements and managing sustainability and risk. Energex is currently working on its Regulatory Proposal for regulatory control period which will be submitted to the Australian Energy Regulator (AER) on 31 October Our Regulatory Proposal will set out indicative prices for Standard Control Services (SCS) and Alternative Control Services (ACS) for The AER will assess our Regulatory Proposal and will release a distribution determination in 2015 which ultimately sets the revenue or prices we are allowed to collect or charge for our distribution services in the next regulatory control period. More information about the Regulatory Proposal is available on Energex s website. 1 This document supports Energex s 2014/15 Pricing Proposal 2 which contains additional information about network pricing, including tariffs and charges and was approved by the Australian Energy Regulator (AER) on 13 June Energex s 2014/15 Pricing Proposal, as approved by the AER, is available on the AER s website at [ /15 Statement of expected price trends

5 2 Network cost drivers Energex is aware of the changing expectations of customers and the current upward pressure being exerted on energy prices. These factors have been considered by Energex, alongside the need to recover its regulated revenue, when developing its 2014/15 network tariffs and charges. Energex is committed to achieving a balanced commercial outcome while meeting its obligations to customers and managing sustainability and risk. 2.1 Regulatory framework Under the current regulatory framework 3, prior to the commencement of a five year regulatory control period, the AER determines Energex s revenue cap for the entire period, including specifying the revenue requirement for each year. In 2009, the AER published the Energex distribution determination for 2010/11 to 2015/16 4 (Final Determination) which detailed the regulated revenue that Energex is required to recover across the period and for each regulatory year. On 19 May 2011, a revised Determination was made by the Australian Competition Tribunal 5 which set revised regulated revenue requirements for Energex for the regulatory control period. Energex s regulated revenue requirements are adjusted annually to determine its Maximum Allowed Revenue (MAR) for that regulatory year. When setting tariffs and charges, Energex does so in a manner that is consistent with clause of the Rules. For Standard Control Services, Energex s objective is to ensure its regulated revenue is recovered from customers through tariffs and for ACS, which are subject to a price cap, the objective is to ensure that the price charged is cost-reflective. 2.2 Cost drivers for 2014/15 For 2014/15, the MAR includes costs to meet: energy, demand and growth expectations security and reliability standards and contemporary network service expectations. The MAR also accounts for approved annual adjustments, including the increasing costs to fund Feed-in-Tariff (FiT) payments associated with the Queensland Government s Solar 3 The regulatory framework exists under the National Electricity Law which is established under the National Electricity (South Australia) Act The current version came into force on 17 April, AER, Energex - Distribution determination to , 4 May Australian Competition Tribunal, Review of a Distribution Determination by Energex Limited, 19 May %2019%20May% pdf /15 Statement of expected price trends

6 Bonus Scheme (SBS) 6, adjustments for Service Target Performance Incentive Schemes (STPIS) 7, and under recoveries. In 2014/15 a reduction to the MAR was made subsequent to a direction from the Queensland Government in relation to the Electricity Network Capital Program (ENCAP) Review Queensland Government SBS The Queensland Government SBS was established to promote the installation of Solar Photovoltaic (PV) by Queensland households and to encourage these customers to export excess energy to the grid through the payment of a Feed-in-Tariff (FiT). Since the introduction of the SBS, the growth in customer uptake of residential Solar Photovoltaic (PV) generators in Queensland has significantly exceeded expectations and is now having a significant impact on network charges which have to account for the cost of these payments ENCAP review For 2014/15, the MAR has been adjusted as a result of the ENCAP Review. Commissioned by the Queensland Government in 2011, the ENCAP Review established an independent panel to undertake a review of the capital infrastructure programs of Energex, Ergon Energy and Powerlink with the view to achieving improved efficiencies and cost savings while maintaining network security and reliability. The panel made a number of recommendations that were endorsed by the Queensland Government and have been implemented by Energex, including revision of the network security standard and significant potential capital expenditure savings. On 11 February 2012 Energex received a Direction Notice from the Queensland Government 8 requiring it to exclude revenue related to the expected reduction in its capital expenditure (capex) program, arising from the ENCAP Review, from its Pricing Proposals for 2012/13 and the remaining years of the regulatory control period. As such, the 2014/15 MAR includes an adjustment for this direction Distribution Use of System (DUOS) overs and unders account To moderate price increases for customers and provide a smooth transition into the next regulatory control period, no under recovery has been included in the prices for 2014/15. Instead, Energex has utilised the provisions of clauses 6.3(a)(6) and 6.4.3(b)(6) of the Rules which allow for the carry forward of balances of a control mechanism from one regulatory control period to the next and for these to be smoothed across the next 5 years of the Regulatory Determination. 6 AER, Determination 2012/13 Queensland solar bonus scheme pass-through for Energex, December Adjustment for STPIS consistent with the S-banking approval from the AER received 22 April Direction Notice issued to Energex by the Queensland Government under section 115 of the Government Owned Corporations Act 1993 (Qld) /15 Statement of expected price trends

7 The timing allows the closing balance of the DUOS unders and overs account as at 30 June 2015 to be carried over into the building block revenue for the next regulatory period, allowing Energex to commence the next regulatory control period with a zero account balance. Energex has consulted with customers and advocacy groups who favoured Energex recovering the balance over a longer period of time to enable price stability given the extent of the under recovery /15 Statement of expected price trends

Expenditure typically resulting in an asset (or the amount Energex has spent on assets). Typically, those customers with electricity consumption greater than 4 GWh but less than 40 GWh per year at a single connection point; or where demand is greater than or equal to 1 MVA; or where a customer has a dedicated supply system with significant connection assets or the customer has contributed to their dedicated connection assets. At Energex we define our customers through their mutual relationships with us. Through the diversity of our local and broader influences, they are the many who influence how we make decisions and provide services to our region. Energex has categorised customers into 4 broad categories: Community and Connected Customers (who we do work for) and Stakeholders and Partners (who we do work with). The amount of electricity energy being consumed at a given time measured in either kilowatts (kw) or kilovolt amperes (kva). The ratio between the two is the power factor. An entity that engages in the activity of owning, controlling or operating a distribution system which is the distribution network, together with the connection assets associated with the distribution network, which is connected to another transmission or distribution system. This refers to the network charges for the use of the distribution network. Refers to the charges incurred for use of the transmission network; previously referred to as Transmission Use of System (TUOS). -A /15 Statement of expected price trends

14 Term Electricity Network Capital Program Review Energy Abbreviation / Acronym ENCAP Definition The ENCAP Review was commissioned by the Queensland Government in late An independent panel was established to undertake a review of the capital infrastructure programs of Energex, Ergon Energy and Powerlink with the view to achieving efficiencies and cost savings while maintaining network security and reliability. The panel identified significant potential capital expenditure savings and Energex s program of capital work was reduced in line with these findings. The amount of electricity consumed by a customer (or all customers) over a period of time. Energy is measured in terms of watt hours (Wh), kilowatt hours (kwh), megawatt hours (MWh) or gigawatt hours (GWh). Feed-in Tariff FiT The rate that is to be paid for the excess energy generated by customers and fed back into the electricity grid under the Queensland Solar Bonus Scheme. The FiT rate is determined by the Queensland Government and is paid by the purchaser of the excess energy. Final Determination Individually Calculated Customer Maximum Allowable Revenue National Electricity Market National Electricity Rules Network Use of System ICC MAR NEM NER (the Rules) NUOS A distribution determination document published by the AER in its role as Energex s economic regulator that provides for distribution charges to increase during Energex s Regulatory Control Period. Typically those customers with electricity consumption greater than 40 GWh per year at a single connection point; or where the customers demand is greater than or equal to 10 MVA; or where a customer s circumstances mean that the average shared network charge becomes meaningless or distorted. The maximum revenue which can be recovered through tariffs for the regulatory year. The interconnected electricity grid covering Queensland, New South Wales, Victoria, Tasmania, South Australia and the Australian Capital Territory. The legal provisions (enforced by the AER) that regulate the operation of the NEM and the national electricity systems, the activities of market participants and the provision of connection services to retail customers. The tariff for use of the distribution and transmission networks. It is the sum of both Distribution Use of System (DUOS) and Designated Pricing Proposal Charges (DPPC). -A /15 Statement of expected price trends
