ElectraNet Role of Transmission in the Market Slide 6 Build, operate and maintain the electricity transmission highways that transport electricity from generators and interconnectors to distribution networks and large direct connect industrial customers. Supply competitive electricity transmission services and high levels of safety and reliability for the benefit of customers. CompetitiveRegulated MonopoliesCompetitive
ElectraNet Slide 7 Network Service Provider (NSP) Network Companies are common carriers of generators and/or retailers energy on a non-discriminatory basis, but are NOT responsible for: –the generation of electricity –the trading or setting of Spot Price for electricity –the operation of the National Electricity Market Networks provide: –least cost transport for generators –reliable and secure power delivery for customers –access to competitive market for participants
ElectraNet South Australian Energy Consumption by Source Slide 8 Trends are: Coal from 35% to 30% - slow decline but relatively constant Gas from high of 55% to 45% - ramped up to replace interconnector then declined Wind from 5% to >20% - growing source, SA Govt target is 33% in 2010 Net Interconnector from high of 18% to low of 0% to 5%
ElectraNet Slide 9 South Australian Emission Levels South Australian electricity emissions are continuing to trend down and are nearly 20% down on 2004/05 peak
Slide 10 Role of ElectraNet
ElectraNet Slide 11 The Roles and Expectations on Transmission Fundamental role – reliable delivery of bulk electricity supply to major load centres The vast majority of ElectraNets five-year investment program is reliability driven: i.e. by the need to keep the lights on in the face of ever increasing demand Investment is only just keeping pace with load growth – just-in-time is the credo The reliability impacts of transmission failures can be severe (e.g. US and London blackouts)
ElectraNet Slide 12 The Roles and Expectations on Transmission Additional role – delivering potentially lower prices by facilitating competition between generators both intra- state and inter-state Competition can be lessened and consumers can be worse off if there is inadequate transmission transfer capacity Unlike for reliability, outcomes to date have been sub- optimal – there have been high wholesale price events - focus has been more on developing a National Electricity Market than a National Electricity Grid – this is changing
ElectraNet 13 Investment and Reliability of Supply Figures around recent and projected price rises are regularly cited in media reports What is less frequently mentioned are the costs to consumers and the costs to business from a lack of reliability because of underinvestment. Lack of reliability in our electricity supply would threaten jobs, threaten business and undermine our economic prosperity. This is why it is so important to get the balance right, why it is vital that we dont stand in the way of required investment… Energy networks play a crucial role in bringing reliable energy to households and businesses – they are the foundation of our modern economy Source: Martin Fergusson speaking at ENA Smart Networks Summit, 18 May 2011
Slide 14 New Generation and Network Development
ElectraNet Renewable and Emergent Technology in SA Coal to Liquids Geothermal Wind Wave Solar Slide 15 Feasibility StudiesConstructionPilotDemonstration Commercially available Grid connection An optimistic view of timelines … Wind is presently the only mature technology; however, Solar thermal is improving and all should reach Grid Parity by 2016
ElectraNet 16 Wind Generation Connection Outlook South Australia has about half of the nations installed wind capacity ~1,200 MW operational and under construction 20% of annual energy requirements are now met by wind Significant potential for further development (SA Govt target = 33% by 2020) Capacity for total wind connections of approx. 2,300 MW Beyond this requires significant transmission investment; e.g. Eyre Peninsula

ElectraNet Slide 18 Future Retail Electricity Prices 31% nominal increase over three years 76% of increase is related to wholesale energy and distribution costs 7% of increase is due to transmission costs Source: AEMC Report, 30 Nov Figures are representative for customers on standing offer contracts
ElectraNet Slide 19 Future Retail Electricity Prices Network costs drivers… – increasing levels of capital works to meet growing demand and replace ageing assets – higher rates of return due to increase in debt premiums following GFC – higher input costs as commodities market recovers from GFC – Changes in reliability standards Source: AEMC Report, 30 Nov 2010.
Munno Para Substation Slide 20
ElectraNet Slide 21 Background A substation is required in the Munno Para region. This facility will provide the bulk supply connection point between the 275 kV line delivered by ElectraNet and the 66 kV distribution supply required by ETSA Utilities. This need was identified after examining supply issues for the northern suburbs 66 kV network. The identification process followed procedures established by the National Electricity Rules. The options considered were subjected to Regulatory Test The process confirmed the necessity to construct the infrastructure in this region, with an energisation date of November 2014.
ElectraNet Slide 22 Background … continued The preferred site was deemed to be must suitable because: – It is located at the connection point between existing 275 kV and 66 kV transmission lines; – It is a level undeveloped site; – The land available is of suitable size; – It has minimal residential development in the vicinity; and – There is an established corridor of trees bordering the road frontages.

This allows for current works, future upgrades, and an appropriate buffer zone. ElectraNet boundary (indicative) ETSA Utilities Boundary (indicative) DTEI boundary (indicative) Allotment Boundary
ElectraNet Slide 24 ETSA Utilities also requires land on which to construct their distribution infrastructure. ETSA will therefore also be a party to this development. DPTI also have secured an adjoining site on which to construct infrastructure for the electrification of the Gawler railway line. Acquisition Partners
