The combined-cycle plant came online in 2002 and features a GE 9F.03 gas turbine and a D10 steam turbine and generator.
The upgrades also include a Dry Low NOx 2.6+ combustion system, an Advanced Gas Path solution, an Asset Performance Management digital solution, a Mark VIe integrated control system and associated gas and steam turbine generator maintenance.
According to GE, the upgrades are expected to improve the plant’s combined-cycle efficiency by up to 2 per cent and its output is expected to improve by 21 MW, or 6 per cent.
The work is planned for the second quarter of 2018.
Steve Glover, director of hard coal and gas power plant UK for RWE Generation, said: “When first commissioned in 2002, the Great Yarmouth facility was one of the UK’s most efficient power stations. Since then, the power industry has grown and evolved, with newer power plants allowing for more efficient and reliable power generation.”
He added that RWE had “contemplated multiple operating scenarios for our Great Yarmouth plant” before deciding on the upgrades.
