Generation

Origin is the largest owner and developer of gas-fired power generation in Australia. Origin also produces renewable energy from wind farms.

Origin has one of Australia's largest generation portfolios with 5,310 MW¹ of capacity (owned or contracted).

Lower-emission gas-fired power generation

Origin has a growing portfolio of power generation facilities, operating eight power stations across New South Wales, Queensland, South Australia and Victoria. Nearly all of Origin’s power stations are fuelled by natural gas. One peaking plant, Mt Stuart in Queensland, is capable of conversion to gas once a reliable gas supply is available.

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

Power generation from wind farms

In 2009, Origin completed its first wind farm at Cullerin Range in New South Wales. Origin is also at various stages in the planning process for several more wind farms and has a total potential wind development portfolio of more than 3,000 MW.

Geothermal, hydro and solar

Origin continues to pursue the development of longer-term renewable energy solutions including geothermal, hydro and solar photovoltaic energy.
