Generation

We're the largest owner of natural gas-fired power stations in Australia. We also produce power from coal, wind, pumped water storage, solar and cogeneration plants.

Our generation portfolio is one of the largest and most diverse in Australia, with the capacity to meet around 13%1 of electricity needs within the National Electricity Market (NEM).

OUR NATURAL GAS-FIRED POWER STATIONS

Gas-fired stations emit around half the carbon of a typical coal-fired power station. We operate six natural gas-fired power stations: one baseload station to provide power for everyday use, and five peaking stations to provide a source of power during peak times.

Darling Downs Power Station, QLD

GENERATION CAPACITY
630 MW

Our Darling Downs Power Station in Queensland is one of the country’s most efficient baseload power stations, running on coal seam gas from reserves in the Surat Basin.

Roma Power Station, QLD

GENERATION CAPACITY
74 MW

The Roma Power Station is a peaking power station and was built and commissioned by the energy business of Boral in 1999, which became Origin in 2000.

Mortlake Power Station, VIC

GENERATION CAPACITY
550 MW

Mortlake Power Station is the largest gas-fired power station in Victoria. The peaking power station is powered by gas from the Otway Basin.

Ladbroke Grove Power Station, SA

GENERATION CAPACITY
80 MW

Ladbroke Grove Power Station is a natural gas-fired peaking power station which became operational in 2000.

Quarantine Power Station, SA

GENERATION CAPACITY
216 MW

Our largest peaking power station in South Australia, Quarantine Power Station on Torrens Island shares the uninhabited stretch of land with a conservation park. It opened with four turbines in 2002 and a 2009 expansion more than doubled its capacity.

Uranquinty Power Station, NSW

GENERATION CAPACITY
640 MW

Uranquinty is one of Australia's largest and most efficient gas-fired peaking power stations.

What is baseload power?

Baseload power stations give us the reliable and relatively low-cost steady supply of power that we use every day and every night.

What is peaking power?

There are times when the demand for electricity is at its highest. Our scorching Australian summers or cold winter nights may stretch the power system to its limits. This is when we need the support of peaking power stations.

Eraring Power Station, NSW

GENERATION CAPACITY
2,880 MW

Eraring Power Station is Australia’s largest power station, and our only coal-fired power station. Acquired in 2013, it is one of the most efficient and lowest carbon-intensity black coal-fired power stations in Australia.

Mt Stuart Power Station, QLD

GENERATION CAPACITY
414 MW

Operational since 1999, Mt Stuart is North Queensland's largest power station, designed to generate electricity at peak times. Mt Stuart uses an open-cycle gas turbine system in which the three turbines are fuelled by Kerosene - the same fuel that powers jet engines. The power generated goes into the NEM which covers Australia’s eastern and southern states.

Cullerin Range Wind Farm, NSW

GENERATION CAPACITY
30 MW

We own and operate the Cullerin Range Wind Farm capturing wind energy using turbines. In producing 100 percent renewable power from the wind, Cullerin Range will help avoid the production of approximately 84,000 tonnes of carbon annually.3

Bendigo and Ballarat Solar Parks, VIC

GENERATION CAPACITY
300 kW

In 2009, the Central Victoria Solar City Program brought together a consortium of local authorities and businesses to develop the Bendigo and Ballarat Solar Parks which generate a total of 710 MWh of power per year.2

Shoalhaven Hydro Pump Storage Scheme, NSW

GENERATION CAPACITY
240 MW

Shoalhaven Pump Storage Scheme consists of two pumped storage hydropower stations at Kangaroo Valley and Bendeela in the Shoalhaven area. Water used to generate electricity during peak demand periods is pumped back, during lower demand periods, to storage headponds above each station ready for when power generation is next required. The facility is also used to supply water to Sydney during times of drought.

Dandenong Cogeneration Plant, VIC

GENERATION CAPACITY
120 MW

In partnership with Places Victoria, the Victorian State Government’s Urban Renewal Authority, Origin established Australia’s first urban distributed energy precinct using cogeneration technology. Cogeneration engines are housed within a purpose built ‘Energy Centre’ in the heart of the precinct. The facility generates electricity from gas fired generators and the waste heat produced in this process is then captured to heat water and provide heating and/or cooling to buildings within the precinct.

Bulwer Island Cogeneration Plant, QLD

Generation capacity
32 MW

As part of the Bulwer Island Energy Partnership, this plant supplies power and steam to the nearby BP Refinery. Bulwer is jointly owned by Origin and Canada’s ATCO Power.

Worsley Cogeneration Plant, WA

Generation capacity
120 MW

Worsley Cogeneration Plant provides steam and power to the Worsley Alumina Refinery and electricity to Western Power Corporation. Worsley is jointly owned by Origin and Verve Energy.

Osborne Cogeneration Plant, SA

GENERATION CAPACITY
180 MW

With both baseload and peaking capacity, Osborne provides electricity to the National Electricity Market. Osborne is jointly owned by Origin and ATCO Power, and Origin contracts 100% of the output.

Contact Energy

Origin has a majority holding in New Zealand’s leading integrated energy company, Contact Energy.
