LONDON, Jan 21 (Reuters) - EDF's British arm said a life extension for its Sizewell B nuclear plant is technically possible but negotiations are ongoing with the UK government to enable the required investment.

Sizewell B nuclear plant in Suffolk supplies nearly 1.2 gigawatts of electricity to the grid and is the only pressurised-water reactor in the UK.

The rest of the nuclear fleet are advanced gas-cooled reactors (AGR), many of which are nearing the end of their life or have been retired.

A few of the AGRs have had their life extended for a few more years amid concerns that Britain faces a looming supply gap due to the age of its nuclear fleet.

EDF and Centrica want their remaining AGRs to operate at least until 2030. Investment to support that would cost 1.2 billion pounds over the next three years, EDF said.

"Work continues to agree a commercial model that is required to support a 20-year Sizewell B life extension (2035-2055) and unlock 800 million pounds of investment in the station," EDF Energy said in a statement.
