STRATEGIC REVIEW 66

STRATEGIC REVIEW In February 2010 Spark Infrastructure announced a Strategic Review to explore and evaluate a wide range of options including capital structure, ownership structure and future funding needs The Asset Companies have indicated they wish to retain a greater proportion of cash from operations to fund the expected increase in growth capital expenditure While increased capital expenditure enhances long term value it potentially impacts on short term cash distributions from the Asset Companies to Spark Infrastructure The available options under the Strategic Review include: changes in corporate structure changes in capital structure capital raisings; and proposals that involve asset sales or a change of control of Spark Infrastructure Detailed consideration of each of these options is still ongoing and well progressed 7

STRATEGIC REVIEW The Board, which operates with a majority of Independent Directors, has put in place governance protocols and established a committee of Independent Directors to: manage any conflicts of interest that may arise within the Strategic Review process regulate the flow of information as appropriate among the Board, the Independent Directors, the Asset Companies, the asset partners (CKI and HKE) and Spark Infrastructure s Manager Deutsche Bank was appointed to act as financial adviser in relation to this Strategic Review. Investec Bank (Australia) Limited appointed to provide advice to the Independent Directors and will work closely with Deutsche Bank It is expected that the Strategic Review outcome will be determined by 30 November 2010. Spark Infrastructure will keep the market appropriately informed of any developments 8

DISTRIBUTIONS TO SECURITYHOLDERS HY 2010 cash distribution of 6.72 cents per security consisting entirely of interest on Loan Notes for the period The outcome of the Strategic Review may impact the composition of the total return to Securityholders in relation to the balance between distribution yield and capital growth in future periods Therefore guidance on future distributions cannot be provided at this time, noting that: Historical distributions are not indicative of future distributions The Asset Companies have indicated a desire to retain a greater proportion of cash from operations to contribute to the funding of growth capital expenditure The Directors expect to be able to provide future distribution guidance by 30 November 2010 9

AGGREGATED FINANCIAL PERFORMANCE (100% results) ETSA, CitiPower and Powercor Half Year ended 30 June 2010 $m 2009 $m Variance % Regulated Revenue 644.5 616.8 4.5 Semi-regulated Revenue customer contributions 127.8 122.7 4.2 Semi-regulated Revenue other 34.7 32.2 7.8 Unregulated revenue 82.6 108.7 (24.0) Total Revenue 889.6 880.4 1.0 Total operating costs 225.2 252.5 10.8 EBITDA 664.4 627.9 5.8 Capital expenditure (net) 254.6 186.2 36.7 Regulated revenue (Prescribed) ETSA Utilities regulated revenue increased by 5.7% due to price increases in accordance with the regulatory formula and favourable impact of weather on residential sales, partially offset by lower consumption. CHEDHA prescribed revenue increased due to increased metering revenue associated with the roll-out of Advance Metering, although electricity distribution revenue fell due to lower rates and consumption Unregulated revenue (Non-prescribed) ETSA non-prescribed revenue fell by 6.8%. Customer contributions increased while other non-prescribed revenue fell due to a reduction in construction and maintenance activity. CHEDHA non-prescribed revenue decreased by 7.3%. Customer contributions fell due to lower construction activity, while other non-prescribed revenue decreased in part due to a reduction in shared services fees charged to related companies Net Capital Expenditure The Asset Companies continue to invest in the expansion of their networks, enhancing asset performance and reliability, and for replacement of existing assets. Capital expenditure is added to the Regulated Asset Base of the Asset Companies which results in increased revenue in future periods Operating costs Operating costs were lower for ETSA Utilities in line with lower unregulated business activity. CitiPower and Powercor recorded lower operating costs due in part to lower materials usage, higher than planned capital expenditure, and capitalisation of the AMI project management fee 20 Note: Comparatives have been adjusted to reflect all metering revenue for CHEDHA as Regulated Revenue

GROWTH DRIVERS ASSET COMPANIES PRIMED FOR GROWTH The Asset Companies in which Spark holds a 49% interest are entering a unique and exciting period of growth based on substantially increasing regulated capital expenditure. This means: Strong growth in their Regulated Asset Bases (RAB) and correspondingly increasing revenues Greater relative returns than growth by acquisition as investment in existing regulated assets occurs at 1.0 times RAB (no acquisition premium) Regulated Return on Equity of around 11% (11.09% ETSA final; 10.85% CHEDA draft) Long term capital growth through net equity investment in RAB Net capital expenditure earns a return from day one and is growing the Regulated Asset Base and therefore growing future returns - Extensive asset replacement programs confirmed by Australian Energy Regulator for ETSA Utilities and proposed for CitiPower and Powercor - Roll-out of Advanced Metering Infrastructure in Victoria provides additional RAB growth and future revenue for CitiPower and Powercor - Steady increases in peak demand for electricity expected in South Australia and Victoria in line with population and economic growth Businesses can benefit from efficiency out-performance The regulated business provides a secure platform for growth 28

GROWTH DRIVERS ETSA UTILITIES Final decision from Australian Energy Regulator provides for strong growth in revenue and the Regulated Asset Base - substantial increases in capital expenditure and operating expenditure allowances to cater for strong asset renewal and expansion programs AER decision has set WACC at 9.76% and Return on Equity now 11.09% ETSA Utilities selected by NBNCo to construct one of five first release sites at Willunga potential for further participation in the future Regulatory period 2010-2015 2005-10 Beta 0.8 0.9 Risk Free Rate 5.89% 5.8% Debt risk premium (DRP) 2.98% 1.65% Market risk premium (MRP) 6.5% 6.0% Nominal vanilla WACC 9.76% 8.95% Nominal post tax return on equity 11.09% 11.2% Gamma (Imputation) 0.65 0.5 Net capex over 5 years ($June 2010) $1,643m $886m 1 Opex over 5 years ($June 2010) $1,066m $760m 1 Revenue (Nominal) $3,637m $2,518m 2 1.

CLOSING COMMENTS 31 32

CLOSING COMMENTS Robust regulatory framework provides a range of built-in protections. Regulatory reset process will conclude this year providing certainty over a new five year regulatory period Strong expected rise in capital expenditure offers long term growth in Asset Company revenues and look-through cashflows High quality businesses with strong management teams generating stable look-through cashflows Strong support from debt markets evidenced. Spark Infrastructure level refinance underwritten. Asset Companies remain well placed to meet future financing requirements. HY 2010 distributions of 6.72cps has been declared and is payable on 15 September 2010 The Strategic Review is well progressed and its outcome is expected to be determined by 30 November 2010 - the Directors expect to be able to provide future distribution guidance by this date 32
