STRATEGIC HIGHLIGHTS WELL POSITIONED TO FUND ORGANIC GROWTH 1. Further strengthening our strong balance sheet Distribution level will conserve capital to fund organic growth of assets Distributions Reinvestment Plan now operational Sufficient capital to fund organic growth requirements in the asset businesses until late 2010 2. Distributions consistently paid from operating cashflows 2009 distribution guidance of 13.56 cents per security Distributions are supported by operating cash-flows Spark payout ratio approximately 70% 3. Capital structure conservative and consistent Successful refinancings at asset level: CitiPower $175 million maturing in February 2010 - mandate agreement signed in August 2009 ETSA Utilities $750 million maturing in April 2010 - $625 million raised via USPP in July 2009; plans for remainder well underway Strong investment grade credit ratings maintained A- for Asset Companies (Standard & Poor s); Baa1 for Spark Infrastructure (Moody s) Net gearing remains steady at 61.3% on a look through basis 1 - in line with regulatory framework Post current refinancings, no refinancing of existing facilities required until December 2010 at fund level ($225 million), and not until June 2011 at asset level 5 1 Net gearing is adjusted for cash on hand and excludes non cash movements in hedging reserve

Net Capital Expenditure Net capital expenditure contributing to growth in the Regulated Asset Base and generates a return from day one Operating costs Reduction in costs largely due to a reduction in construction and maintenance costs (off-setting reduction in unregulated revenues) and greater capitalisation of internal costs to capital projects 14 within ETSA Utilities

STRATEGIC ISSUES 20

REGULATORY ENVIRONMENT FRAMEWORK AND TIMELINES The Australian Energy Regulator (AER) will apply the same building block arrangement for revenue allocation and similar service and efficiency incentive mechanisms as in the past. WACC Parameters - AER Final Decision issued 29 May 2009 (Compared to current regulatory period 2005/6 to 2010/11) Equity beta 0.8 (from 1.0) Benchmark credit rating BBB+ (no change) Imputation credits value 0.65 (from 0.5) Risk free rate proxy 10 year Commonwealth bonds (no change) Market Risk Premium 6.5% (from 6.0%) Regulatory Reset Milestones ETSA Utilities CHEDHA Business submits Regulatory Proposal 1 July 2009 (complete) 10 November 2009 Issue of Draft Decision 27 November 2009 30 July 2010 Business submits revised Regulatory Proposal 14 January 2010 10 September 2010 AER issues its Final Decision 30 April 2010 30 October 2010 New distribution prices come into effect 1 July 2010 1 January 2011 21

GROWTH DRIVERS CITIPOWER AND POWERCOR Advanced Metering Infrastructure (AMI) or smart meters Roll-out commences in September 2009 WACC parameters agreed under old rules - Beta 1.0, Gamma 0.5 Project involves capital investment for CitiPower and Powercor of approximately $690m Majority of required funding will be raised at the asset level Partnerships announced in June for advanced, reliable and efficient delivery Landis+Gyr and PRI will provide smart metering units Bilfinger Berger and UXC have been awarded the field installation contracts Silver Springs networks will provide IP based network infrastructure Roll out end date 2013; around half of the capital expenditure required in 2012-2013 Accelerated depreciation benefits to revenue provided by 15 year asset life Supply security project for the Melbourne CBD The project will be undertaken in three stages and will run over four years starting from 2009. All capital expenditure is added to the Regulated Asset Base and generates a return from day one 22 22

GROWTH DRIVERS ETSA UTILITIES Regulatory submission proposes strong growth in RAB ETSA Utilities lodged its submission to the Australian Energy Regulator in July 2009, which proposes that $2.8 billion be spent expanding and improving its network over the next five years with revenues to be set accordingly The proposed expenditure aims to: Support the gradual restructuring of the South Australian economy based on defence, mining and tourism Meet the demands of State programs of infrastructure investment in water and public transport Progressively replace and augment ageing assets Support mandatory changes in the transmission sector Specific projects span the Adelaide CBD and regional areas. Sample projects: City-West connection, new substation and safety upgrades $154m Low voltage line and transformer upgrade $112m Kangaroo Island second undersea cable and new backbone $80m New network control centre $43m Metropolitan line and substation replacement and upgrades $250m Regional line and substation replacement and upgrades $190m All capital expenditure is added to the Regulated Asset Base and generates a return from day one 23 23

GROWTH DRIVERS CAPITAL MANAGEMENT Completed initiatives Distribution level reduced to conserve capital to provide funding for capital expenditure within the Asset Companies guidance 13.56 cents per security for 2009 Distribution Reinvestment Plan activated for September 2009 distribution Important considerations Capital expenditure is likely to double in the next regulatory reset period (including Advanced Metering Infrastructure) Equity will be required to finance a portion of growth capital expenditure Spark Infrastructure will consider further initiatives in late 2010 when the regulatory reset process is complete 24

GROWTH DRIVERS ACQUISITION INVESTMENT STRATEGY Disciplined approach to acquisitions will be maintained - no pressure to acquire given the strength of organic growth opportunities Will only invest where it enhances shareholder value Acquisitions in the current market environment remain challenging Focus in 2009 will remain on organic growth opportunities within the current portfolio 25

CLOSING COMMENTS 26

CLOSING COMMENTS DISCIPLINED GROWTH Robust regulatory framework provides a range of built-in protections. Asset companies are well prepared for upcoming regulatory resets High quality businesses with strong management teams generating stable cashflows Strong balance sheet and conservative capital structure well positioned to fund future organic growth opportunities Capital funding plan in place for 2009 and 2010 Prudent distribution policy Distribution Re-Investment Plan now in operation, excess cash retained to fund growth Distributions underpinned by operating cash flows interim distribution of 6.72 cents per security declared and payable on 15 September 2009 - maintain total distribution guidance of 13.56 cps for 2009 Strong support from debt markets evidenced. Asset Companies remain well placed to meet future financing requirements Maintain disciplined approach to acquisitions 27

Outline of Proposal Current classification of services maintained Capex: $2.8 billion total (cf. $1.2 billion) Opex: $226 million/annum (cf. $148 million) Various pass-throughs also proposed Form of control: Weighted Average Price Cap Various incentive schemes: Service Target Performance Incentive Scheme Demand Management Incentive Scheme Efficiency Benefit Sharing Scheme Price: 10% per annum increase real Revenue: $550 million (09/10) $800 million (14/15) - real 30

Key cost drivers Peak demand growth Economic growth, development & demographic change Security of Supply CBD/KI Response to extreme weather events Age & condition of network Growth in network, work volume & workforce Input cost escalation wages & services Maintaining risk profile, asset utilisation & reliability 31

Key projects CBD Connection City West Substation to CBD and Southern network ($91m) Fifth CBD substation ($20m) CBD safety upgrade ($43m) Metropolitan Upgrade LV residential network ($112m) involving replacement of existing transformers (700 per annum, of approx. 18,000 in total) New sub-transmission lines to reinforce capacity and security of supply (Willunga, Kilburn, Glynde, Seaton, Queenstown) ($39m) Replace 3 obsolete substations - Woodville, Cheltenham, QEH ($12m) Statewide Major upgrade/expansion of 15 regional substations ($113m) Substation security fencing upgrades ($17m) New network operating centre and SCADA system to better manage the network and improve supply restoration ($43m) Kangaroo Island security ($80m) Major customer connections ($112m) 32

WACC status Proposal adopted AER s Statement of Regulatory Intent (SoRI) parameters, except: Gamma (from AER 0.65 to ETSA 0.5); and Market Risk Premium (MRP) (from 6.5% to 8.0%) Deviations from SoRI reflect new evidence and/or current circumstances Also, have calculated cost of debt using average of Bloomberg & CBA Spectrum AER prefer Bloomberg only In combination, results in WACC of 9.52% (vs AER s 8.29%) Based on rates for Jan-Mar 09 33

Outlook & next steps Too early in review to predict outcome The AER s consultants are undertaking their reviews Next key milestone is draft determination 34
