Customer service levels & safety performance • CitiPower’s commitment to customer service is demonstrated by: – average complaints per 1,000 customer below the industry average since 2002 – a reduction in complaints escalated to the Energy and Water Ombudsman – consistently high satisfaction ratings across residential customers (79 per cent), major customers (86 per cent) and retailers (89 per cent). • CitiPower was recognised with a Highly Commended Award at the 2008 National Safety Awards of Excellence 9

Proposal highlights - CP • Forecast net capital expenditure of $1,058m ($2010) • Forecast operating expenditure of $222m ($2010) over 2011-15 • Maintenance of existing reliability and quality levels • Enhancement of system security in the CBD • Mitigation of fault level exceedence in the CBD and surrounding areas • Maintain ‘energy at risk’ at or below 2010 levels • Continued renewal of urban areas driving new connections • Prudent replacement of aging assets • Introduction of smarter network technologies using AMI functionality 10

Expenditure development process • Methodology: Safety – Capex: bottom-up approach based on asset management plans & demand forecasts Reliability – Opex: revealed costs using recurrent efficient 2009 as base year Security – Where appropriate subject to external advice/ review • Based on prudent asset Quality management plan • Subject to rigorous governance Price process • Aimed at meeting NEL objectives & rule requirements 11

Energy forecasts & Max demand trends Energy forecasts Maximum demand • Energy consumption used in • Maximum demand used in establishing prices determining Reinforcement Capex • Energy forecasts developed by NIEIR • Forecasted internally and verified with NIEIR • Energy forecasts influenced by: • Maximum demand influenced by: � Government energy policy � Economic conditions � Global financial crisis impacts � Population growth � AMI � Appliance purchase & usage patterns 12

Work program drivers – peak demand & asset utilisation • Peak demand growth driven by air • Expenditure driven by highest conditioning: utilised assets – 2009 heatwave, record demand – New phase, from penetration to upgrade CitiPower Load Profile 1500.00 Hot Days 1400.00 1300.00 1200.00 1100.00 Warm Days g 1000.00 in 29/01/09 at 43.2oC d 900.00 a lo 28/01/09 at 43.2oC 800.00 d 17/02/09 at 31.7oC e Mild Days lis 700.00 06/02/09 at 33.1oC a rm 600.00 12/02/09 at 23.7oC o N 20/02/09 at 24.5oC 500.00 400.00 300.00 200.00 100.00 0.00 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 :0 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 0 1 1 1 1 1 1 1 1 1 1 2 2 2 2 Time of Day - Eastern Standard Time 14

Work program drivers – energy at risk • Containment of energy at risk to 2010 levels: - energy at risk has more than doubled in last 4 years - implies augmentation expenditure levels greater than historic levels CitiPower Network 2006-2015 Zone Sub Energy at Risk (EDPR Iteration 2) 140,000MWh 120,000MWh 100,000MWh 80,000MWh 60,000MWh 40,000MWh 20,000MWh 0MWh 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 Energy at Risk (MWh) - Do Nothing - Using expanded DSPR forecasts Energy at Risk (MWh) - With Augmentation - EDPR Iteration 2 15

Work program drivers – Ageing assets Asset Replacem ent: • Portfolio of ageing assets • Average age in excess of 40 years • Increasing risk of higher failure rates and rising maintenance costs • Prudent conditioning monitoring to manage risk - replacement of poles - replacement of underground cables - Replacement of major plant 16

Demand management • Network planning process to identify and implement demand management alternatives where they are economically efficient • Demand management and/ or non network initiatives: – West Melbourne • Extent to which demand management and/ or non- network alternatives are considered depends on: – CitiPower receiving expressions of interest from proponents of feasible alternatives – advances in technology which may lead to a greater number of viable and feasible alternatives 17

Key investments 2011-15 Reinforcement of a highly utilised network – Metro 2012 Capacity Upgrade – CBD Security Upgrade – Regulatory test process completed for both projects CBD Security Metro 2012 80 70 ) m $ 60 0 1 0 t (2 50 n e 40 m ce rm 30 fo in 20 e R 10 0 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 Year 18

Key investments 2011-15 • Enabling connection of embedded generations whilst ensuring security of the network – maintaining fault levels at or below plant and equipment ratings has become an increasing challenge due to an increase in embedded generators – installation of impedance reactors to ensure compliance with fault levels – proposed charge being levied on embedded generation connections • Safety and the environment – noise control – drainage of oil and asbestos management • Creating a network for the future – AMI leveraged projects – replacement/ renewal of the SCADA network 19

Approach to operating expenditure forecasts • Use revealed cost methodology using 2009 as base: – most recent actual performance (5 months of forecast) – efficiency carry over mechanism applies – audited accounts available before AER final decision ± Add/ subtract changes in service classification ± Add/ subtract change in overhead allocation + Add step changes + Add scale escalation for growth across network + Add cost escalation = Forecast operating expenditure 20

Opex – key drivers of cost increases Scope Step Changes: $24m – Climate change Debt raising costs: – Demand Management $22m (WMTS) – Insurance – Self insurance – AEMC Distribution Planning Rule changes – Safety management Scale escalation: $20m Input cost escalation: – Increased network size $19m – Increased work volume – Increased labour – Additional customers – Increased materials 21
