Electricity Industry Overview ______________________________________________________________________ 4 __________________________________________ Auditor-General’s Report to Parliament 2009 Volume Three The Strategy comprises the following key elements:  continued Government ownership and operation of existing power stations and all electricity networks (the pole and wires) in New South Wales  contracting the electricity trading rights of power stations to the private sector, commonly referred to as the ‘Gentrader’ model  selling the retail arms of EnergyAustralia, Integral Energy Australia and Country Energy  selling the following key power station development sites around the State. Development Site Size (MW)* Fuel Progress Bamarang (Delta) 300-400 Gas Full Development Approval obtained Tomago (Macquarie Generation) 500-790 Gas Full Development Approval obtained Marulan (EnergyAustralia) 350 Gas Director-General’s requirements issued (1) Marulan (Delta) 350-450 Gas Director-General’s requirements issued (1) Munmorah (Delta) 700 Gas/coal Planning process underway Bayswater B (Macquarie Generation) 2000 Gas/coal Planning process underway Mt Piper extension (Delta) 2000 Gas/coal Planning process underway (1) On 8 October 2007 the Director-General of the New South Wales Department of Planning declared the Marulan Gas Turbine Facilities Projects of EnergyAustralia and Delta Electricity were considered as Major Projects and would be assessed under Part 3A of the Environmental Planning and Assessment Act 1979. * MW = Megawatts The Strategy’s completion date is mid 2010. The Government retains the discretion to offer particular assets as part of an Initial Public Offering (IPO) should the first phase of the bid process not deliver the Strategy’s objectives. In September 2009 the Government called for Expressions of Interest (EOI) from national and international electricity industry operators and investors. The EOI closes on 18 November 2009. Those offering an appropriate EOI will be invited to submit bids for the assets. The Government’s Strategy is intended to significantly increase private sector investment in new generation capacity for New South Wales. Achieving this objective may require a trade-off between maximising the financial return to the Government and minimising potential ongoing Government liabilities. There are a number of challenges associated with implementing the Strategy. Two of the more significant are uncertainty of the Federal Government’s proposed Carbon Pollution Reduction Scheme and the current global financial climate.

Most of the consideration points are reflected in the current Strategy. The following table provides a comparison between the consideration points and the current Strategy: Consideration points from ‘Oversight of Electricity Industry Restructuring’, August 2008 Items included in the ‘New South Wales Energy Reform Strategy: Approach to transaction implementation, September 2009’ Encourage new entrants and new investment to promote competition in electricity generation and retail markets by:  using simultaneous rather than sequential Generator/Retailer transactions  holding separate tender(s) for a generation development site(s) The Strategy proposes that it will separately and on a simultaneous basis:  contract the electricity trading rights of Government-owned power stations  sell the retail arms of EnergyAustralia, Integral Energy Australia and Country Energy  sell key power station development sites around the State. Treasury continuously evaluate the restructuring process after the marketing effort and before the first transaction. Treasury advised that it has conducted a considerable consultation process which included potential trade purchasers prior to announcing the strategy. Treasury continuously evaluate the likelihood of the success of transactions and whether contingency plans require executing The implementation process advises that if the trade sale process does not deliver the Government’s objectives, the Government retains the discretion to offer particular assets as part of an Initial Public Offering. Reserve Price and Retention Value:  Treasury documents contingency plans prior to commencing the first transaction which inter alia include the setting of a reserve price for each transaction and considerations if the reserve price is not achieved  Treasury calculating a retention value for each Generator and Retailer using consistent assumptions prior to commencing each transaction. The Strategy does not publically articulate Treasury’s approach to either of these points. Access to fuel supply To support the sale by providing some certainty over coal supplies and coal costs, a new coal mine (Cobbora) will be developed to supply State owned generators. The Cobbora open-cut coalfield covers a 320 kilometre area in the Cobbora and Laheys Creek area of Warrumbungle Shire. This is trial version www.adultpdf.com Electricity Industry Overview ______________________________________________________________________ 6 __________________________________________ Auditor-General’s Report to Parliament 2009 Volume Three The Government has approved an initial development budget of about $170 million for New South Wales generators to implement the project. Of the seven State owned power stations five are in the Hunter region and can receive coal from the Cobbora mine by rail. Existing rail infrastructure is to be enhanced and expanded. Expressions of interest have been invited from parties interested in building and operating a large scale coalmine. Indicative offers are due by 5 February 2010 with initial deliveries of coal due to commence from early in 2013. Electricity Prices Electricity wholesale prices in the National Electricity Market (NEM) decreased during 2009. The average spot price for 2009 in New South Wales was $38.85 per megawatt hour, a fall of 6.75 per cent from the 2008 average of $41.66. The wholesale (spot) price of electricity has been subject to volatility since the inception of the National Electricity Market in 1997. Despite this volatility, the average spot price has remained around $40-$45 per megawatt hour. A report by IPART in 2004, ‘The Long Run Marginal Cost of Electricity Generation in New South Wales’, estimated the long run marginal cost (LRMC) for base load thermal generators to be an average of $36.33 per megawatt hour. The same report concluded that the LRMC for two other technologies, combined cycle gas turbines and open cycle gas turbines, to be $41.77 and $58.99 per megawatt hour respectively. These costs currently do not include the cost of carbon. Renewable energy targets and carbon reduction schemes seek to use market forces to encourage investment in renewable and low carbon energy sources. Both State and Commonwealth governments have progressively introduced renewable energy targets and carbon reduction schemes. Under the existing market rules for the NEM average spot prices can range between a minimum of negative $1,000 and a maximum of $10,000 per megawatt hour. The price volatility initially impacted the valuation of generation assets by introducing uncertainty to cash flows and returns to investors. In response, larger market participants manage the impact of price volatility through the use of electricity fixed price contracts (derivative financial instruments). The following tables relate to the average annual wholesale spot prices of electricity: Year ended 30 June NSW $/MWh Vic $/MWh Qld $/MWh SA $/MWh Tas $/MWh 2009 38.85 41.82 34.00 50.98 58.48 2008 41.66 46.79 52.34 73.50 54.68 2007 58.72 54.80 52.14 51.61 49.56 2006 37.24 32.47 28.12 37.76 56.76 2005 39.33 27.62 28.96 36.07 190.38 2004 32.37 25.38 28.18 34.86 (a) Source: AEMO price statistics average annual prices per financial year.

Sustainable Energy The Government is developing and encouraging initiatives to promote the growth of sustainable energy sources. Initiatives in this area are detailed below. Renewable Energy The relatively higher cost of providing renewable generation has been a barrier to any large scale investment. Renewable energy is energy sourced from alternative sources such as water, biomass, landfill methane, wind, organic matter and the sun. This is trial version www.adultpdf.com Electricity Industry Overview ______________________________________________________________________ 8 __________________________________________ Auditor-General’s Report to Parliament 2009 Volume Three Sourcing renewable energy reduces greenhouse gas emissions. Approximately six per cent of New South Wales electricity is sourced from renewable energy sources. The New South Wales Government has set a target of 15 per cent renewable energy consumption by 2020. This target has been largely superseded by the expanded national Renewable Energy Target (RET), which was developed through COAG and mandates that 20 per cent of energy production in Australia come from renewable sources by 2020.

The objectives of the GGAS are to:  reduce greenhouse gas emissions associated with the production and use of electricity  develop and encourage activities to offset the production of greenhouse gas emissions. GGAS requires retailers and other parties (benchmark participants) to meet mandatory targets set under the Electricity Supply Act 1995 for reducing emission of greenhouse gases from the production of the electricity they supply or use. The State’s greenhouse gas benchmarks under the Electricity Supply Act 1995 are as follows: Source: Independent Pricing and Regulatory Tribunal, ‘Compliance and Operation of the NSW Greenhouse Gas Reduction Scheme during 2008’, July 2009 tCO2e = tonnes of carbon dioxide equivalent. It is a measure used to compare different greenhouse gasses. The benchmark dropped to 7.27 tonnes in 2007 which represents a reduction of five per cent below the Kyoto Protocol baseline year of 1989-90. The GGAS is expected to transition into the Federal Government’s Carbon Pollution Reduction Scheme (see below). Most of the demand side abatement aspects of the GGAS were incorporated into the New South Wales Energy Savings Scheme on 1 July 2009, with the exception of on-site generation which remains an eligible activity under GGAS. Customer initiatives - GreenPower GreenPower is a national accreditation program that sets stringent environmental and reporting standards for renewable energy products offered by electricity suppliers to households and businesses across Australia. When customers choose to buy a GreenPower product through their electricity retailer the extra price they pay is invested in the renewable energy sector. This is trial version www.adultpdf.com Electricity Industry Overview ______________________________________________________________________ 10 _________________________________________ Auditor-General’s Report to Parliament 2009 Volume Three Data sourced from the National Greenhouse Accreditation Program shows considerable growth in the number of customers opting to purchase green energy. In New South Wales for the nine month period to 31 March 2009, GreenPower customers increased by 26,069 or 11.8 per cent from 30 June 2008. The increase in green energy purchases was not spread equally between residential and commercial customers. The two graphs appearing below highlight that residential customers in New South Wales increased from 207,801 to 236,242 or 13.7 per cent at 31 March 2009, while commercial customer numbers decreased from 13,021 to 10,649 or 18.2 per cent for the same period. The decline in green energy purchase by commercial customers may in part be indicative of the overall global financial crisis and its impact on the businesses in the economy.

The FiT will apply to small scale, grid connected, solar photovoltaic (PV) systems. A tariff of 60 cents per kilowatt hour will be paid to PV system owners for electricity produced by the systems that are fed back into the electricity grid (a ‘net’ tariff). Electricity distributors are expected to bear the costs of the scheme with the costs being passed onto electricity customers. Households are expected to pay on average between $2 and $9 per year over the life of the scheme to fund the Scheme. Carbon Pollution Reduction Scheme (CPRS) All Australian businesses, including all electricity corporations in the New South Wales Public Sector, will be affected directly or indirectly by the Federal Government’s proposed CPRS. In December 2008, the Federal Government released a White Paper outlining its policy for a national CPRS emissions trading scheme. On 4 May 2009, the Federal Government announced a number of adjustments to the scheme to address public concerns and help manage the impacts of the global recession. The key variations included: delaying the scheme’s commencement by one year to 1 July 2011; establishing a fixed price of carbon of $10 for the first year of the scheme; a global recession buffer, providing additional assistance to emission intensive trade-exposed industries (EITE) for the first five years of the scheme; announcement of a new emissions reduction target in the event of an ambitious international agreement; and measures to account for the impact of voluntary action to reduce abatement. After the first year of the scheme, carbon prices will revert to being set by the market. Depending on the outcome of international negotiations, the CPRS will help achieve emission reductions of between 5 and 25 per cent below 2000 levels. From the scheme’s outset it will cover around 75 per cent of Australia’s emissions, including those from stationary energy, industrial processes, transport, fugitive emissions, waste and forestry. Draft legislation was released earlier this year to implement this policy. As at October 2009 this has been passed by the House of Representatives, but voted down in the Senate. It is expected to be brought before the Senate again in November 2009. Electricity Supply and Demand Outlook Projected electricity demand in New South Wales is currently expected to exceed supply by 2015-16. The AEMO provides the supply and demand outlook for each State, which includes:  an indication of the capability of existing and committed supply to meet projected demand for the next ten years  the Low Reserve Condition (LRC) point, which indicates when reserves will fall below the required level to avoid possible shortage of supply  the Reserve Deficit in megawatts (MW), which indicates the additional reserves potentially required at the LRC point. This is trial version www.adultpdf.com Electricity Industry Overview ______________________________________________________________________ 12 _________________________________________ Auditor-General’s Report to Parliament 2009 Volume Three Summary Overview of LRC and Reserve Deficit State LRC Point Reserve Deficit (MW) New South Wales 2015-16 182 Queensland 2014-15 34 Victoria and South Australia (combined) 2013-14 17 South Australia (local) 2012-13 68 Tasmania Beyond 2018-19 Source: AEMO Statement of Opportunities 2009. Highest Demand in Summer For New South Wales, the tightest supply-demand conditions are expected to occur during summer. The summer supply–demand outlook for the New South Wales region for the next ten years is shown in the chart below: Source: Extracted from AEMO Electricity Statement of Opportunities for the National Electricity Market 2009. (a) Allocated Installed Capacity: Represents the current projection of installed generation capacity allocated to meet the reliability requirement for the region (Capacity for Reliability). It includes the available capacity within a region plus the allocated net import from neighbouring regions. (b) Additional Capacity Required: Represents the difference between the Capacity for Reliability and the Allocated Installed Capacity or the MT PASA (Medium Term Projected Assessment of System Adequacy) Available Capacity. This also represents the reserve deficit. (c) MT PASA Available Capacity: Represents the operational projection of installed generation capacity available to meet the scheduled maximum demand. This projection is taken from the preliminary MT PASA calculation performed using available capacity bid into MT PASA as at 24 July 2007. (d) Capacity for Reliability: represents the capacity that needs to be allocated to meet the minimum reserve level. The New South Wales low reserve condition point occurs in 2016 when the additional capacity required is 182 megawatts. If this additional capacity is not created by this time, supply will fall below minimum reserve levels (as indicated by the solid line), which may necessitate load shedding and periods of blackouts for some customers.
