On the right is a CCGT type power station running on natural gas. There are two General Electric Frame 9FA gas turbines each rated at 250 MWe. The total thermal input is 1329 MW. Each gas turbine is connected to a heat recovery steam generator which connect to one steam turbine which has an output of 260 MWe. Steam is condensed using water from the River Trent. There is a 25 MWe 11 kV gas turbine available for black starts when there is no power to start producing electricity. The station connects to the National Grid at 400 kV, being used for baseload.

Keadby 2

In 1999, Scottish Hydro applied to add another 710 MWe of capacity at Keadby, and a variation to this consent was granted in November 2016. The project, called 'Keadby 2', was announced in May 2018.

Construction on the plant on the left, now rated at 893 MWe, began in August 2018. The station was planned to come online in October 2022, but this date was missed, with the plant coming online in February 2023.

Keadby Three

In December 2022, development consent was obtained for a third plant on the Keadby site. Keadby Three is planned to be a 910 MWe plant with carbon capture and storage, with opening planned as soon as 2027.
