Specification

It is a CCGT-type power station that uses natural gas. It has two Alstom 260MWe GT26A gas turbines, with an Alstom heat recovery steam generator each that produces steam for one ABB 280MWe steam turbine. The plant runs at 58% thermal efficiency. 300MWe is used by the Ineos site (previously ICI) at Weston Point that makes hydrofluororcarbons (HFCs), and the other 400MWe is sold by Scottish and Southern Energy (formerly Scottish Hydro) for electricity supply.
