Electricity Generation

Electricity Generation

Origin operates Australia's largest power generation portfolio with 6,010 MW of capacity. This represents approximately 13 per cent of power generation capacity in the National Electricity Market 1.

Origin is one of the largest owners and developers of natural gas-fired power generation in Australia. We also produce power from other fuel sources, including black coal and renewable energy from wind farms.

Lower-emission gas-fired power generation

Origin operates six natural gas-fired power stations across New South Wales, Queensland, South Australia and Victoria.

When used for electricity production, natural gas produces less carbon emissions than a typical coal-fired power station. Combined cycle gas turbine technology, such as that used at Origin's Darling Downs Power Station, is the cleanest in terms of carbon emissions, producing less than half of the carbon emissions of a typical coal-fired power station.

Origin also operates Australia’s largest power station, Eraring Power Station, located near Lake Macquarie in New South Wales. Eraring is one of the most efficient and lowest carbon intensity coal-fired power stations in New South Wales. It is crucial to maintaining a reliable supply of energy across the state, providing approximately 25 per cent of its power.

In addition, Origin has a 50 per cent interest in three co-generation plants which supply electricity and steam under long-term contracts. View a complete list of Origin's power stations.

Power generation from wind farms

Origin has an extensive portfolio of owned and contracted wind generation. In 2009, Origin completed its first wind farm at Cullerin Range in New South Wales. Origin also contracts a large amount of wind power from other wind generators to meet the green energy demands of our customres. Origin continues to progress towards a final investment decision the Stockyard Hill Wind Farm in Victoria. When developed, this will be one of the largest wind farms ever built in Australia.
