The owners of Barking power station in east London could shut up shop in two years because it is no longer economic to run a gas plant.
Today Barking Power announced talks with staff on closing the 1,000 megawatt (MW) combined cycle gas turbine (CCGT) plant – one of the more efficient types.
But the station was built in the early 1990s and fired up in 1995 and so has a lower thermal efficiency than more recent ones.
In a statement the firm blamed “the current adverse market conditions for gas fired power generation”.
Run by Thames Power Services, the plant employs 38 people.
