Drax Group operated by the Central Electricity Generating Board (CEGB), Drax Power Station was constructed and commissioned in two stages. Stage one (units 1, 2 and 3) was completed in 1974. Some 12 years later in 1986, stage two (units 4, 5 and 6) was completed. Drax was the last coal-fired power station to be built in the UK, and was initially designed to use low-sulphur coal from the nearby Selby coalfield in six generating units. Each unit has a capacity of 660 MW when burning coal, giving a total capacity of just under 4 GW. This made Drax the largest power
Drax power station scheduled begin in late 2010 and to take up to three and a half years. Two other 300 MW biomass plants were planned by Drax at the ports of Hull and Immingham. In 2012 Drax group abandoned plans for the discrete biomass plant development, due to changes in government subsidies for biomass energy production favouring plant conversions over newly built plants. It switched to a project to convert half of the units at its existing plant to biomass firing. In September 2012 Drax Group announced the conversion to full firing with biomass of three of its six units. The first
