EDF has extended the operating lifetimes of four nuclear units at two of its UK nuclear power stations by two years, a move that means all nine commercial reactors in the country have been granted extensions.

Heysham A in Lancashire, northwest England, and Hartlepool A in Teesside, northeast England, are now expected to produce electricity until March 2030, the French state company and UK nuclear fleet owner said.

It said extending the generating lives of the plants could boost nuclear output by 28 TWh over the two-year period, enough to power 8.4 million homes.

Before the decision to extend operations Heysham A and Hartlepool A were due to move into defueling in March 2028.
