No energy business in Australia does more in demand management and energy effi ciency than EnergyAustralia. Our Five Year Network Plan: 2009—2014 3 About EnergyAustralia EnergyAustralia is one of the largest energy suppliers in the country with more than 100 years experience in providing a safe and reliable supply of electricity. We operate the largest electricity network in the country, uniquely comprised of both transmission and distribution systems that supply electricity to more than three million people in Sydney, the Central Coast and the Hunter Region. Our electricity network includes The performance of our network more than 49,000km of both has remained stable over many At a glance overhead and underground years, with a safe power supply – In 2008/09 our electricity powerlines, 41 subtransmission available 99.98 per cent of the network distributed more than substations, 177 zone substations time. We have maintained our 30,000 GWh of electricity to and 29,974 distribution substations. performance despite undergoing homes and businesses. Together this electrical equipment rapid periods of growth to keep pace supplies 1.6 million customer with development, meeting demand – This is about 51 per cent of connections. and renewing our assets. all the electricity consumed in NSW. This network serves a wide range And with demand for power of communities from rural towns, continuing to grow, particularly – It was delivered via 4,570km rugged mountain communities and on our summer peak days, we are of 132,000 volt, 66,000 volt regional centres to the Sydney CBD working to maintain this reliable high voltage transmission and the Homebush Olympic site. It supply by delivering an $8 billion lines, 17,361km of high voltage is powering key industries across capital program. distribution lines; and 27,615km of low voltage distribution lines. these regions including mining, EnergyAustralia is committed manufacturing, oil refi ning, shipping, to fulfi lling our Duty of Care, – More than 3,500 front line engineering and agriculture. complying with legislation and workers help to maintain and licence conditions, maintaining upgrade our electricity network, asset integrity, improving reliability including more than 640 over time and meeting the demand apprentices and engineering for about 17,000 new network graduates. customer connections each year. – EnergyAustralia is the single largest employer of apprentices in NSW. 4 EnergyAustralia Investing for Future Generations About six kilometres of underground tunnel carrying high voltage transmission cables will be created to form a ring, picking up new and upgraded substations. Committed projects and the new CityGrid Project make up the $1 billion investment.
