There are currently 32 active gas fired combined cycle power plants operating in the United Kingdom, which have a total generating capacity of 28.0 GW. [1]
In 2016 gas fired power stations generated a total of 127 TWh of electricity. Generation has dropped to 119 TWh in 2017, 115 TWh in 2018, 114 TWh in 2019 and 95 TWh in 2020. The decline is largely due to the increase in renewable sources outweighing the decline of coal, and an overall reduction in demand. [2]
