Braemar Power Station, 2006 Oakey Power Station, 2016. These gas turbine power stations use gas combustion to generate some or all of the electricity they produce. Combined cycle plants include an open cycle gas turbine, plus a heat recovery steam generator that uses waste heat from the gas turbine to make steam to drive a steam turbine.
The primary fuel for electricity generation in the state is coal with coal seam gas becoming a significant fuel source. Queensland has 98% of Australia's reserves of coal seam gas. An expansion of energy-intensive industries such as mining, economic growth and population growth have created increased demand for energy in Queensland. [2]
Power generation in the Cairns region was expanded in 1935 with the opening of Queensland's first significant hydro-electric power station at Barron Falls, containing 3 x 1.32 MW generators, this being considered more cost effective than railing coal from the Bowen Basin. The expanded capacity enabled Atherton and Gordonvale to be supplied from ...
Queensland is the most decentralised mainland state, and initial local generation and distribution was the only viable option for the supply of electricity in many instances. The creation of regional, and then a statewide network from 1945 enabled economies of scale and reliability to be obtained, particularly by generating plants .
The declining cost of renewable energy sources, such as solar power, wind power and battery storage, means it is unlikely a new coal-fired power station will ever be built in Australia. [2] The Liddell Power Station is the latest major coal-fired power station to be decommissioned, which took place on 28 April 2023. [3]
Following a review by the Treasurer of Queensland of the state's electricity sector in 2010, Tarong Energy became a wholly owned subsidiary of Stanwell Corporation on 1 July 2011. [4] The Mackay Gas Turbine was decommissioned in April 2021 and no longer supplies grid power to the National Electricity Market (NEM).
It was opened by the Queensland Premier Anna Bligh and Minister for Mines and Energy Geoff Wilson on 27 November 2007. [6] The fuel source is the Kogan Creek coal deposit, which is also owned by CS Energy and will provide 2.8 million tonnes of black coal annually. [7] The coal is delivered to the power station via a 4 km long conveyor belt.
The Barron Gorge Hydroelectric Power Station (or Barron Gorge Hydro) in Queensland, Australia is an electricity power station commissioned in 1963 with a maximum capacity of 66 megawatts (89,000 hp). It is in the locality of Barron Gorge in the Wet Tropics World Heritage Area 20 kilometres (12 mi) north-west of Cairns . [ 1 ]
