RWE Generation (RWE) has selected GE’s Power Services business to provide plant equipment upgrades and advanced digital solutions, aiming to enhance the competitiveness, reliability and flexibility of its Great Yarmouth power station in Norfolk, U.K. The upgrade will take place in the second quarter of 2018.
As power plants age and energy consumption increases, GE said its Fleet360 total plant solutions will provide RWE with new ways to add years to the life cycle of its Great Yarmouth power station while also increasing the amount of electricity it transmits to the grid.
“When first commissioned in 2002, the Great Yarmouth facility was one of the U.K.’s most efficient power stations said Steve Glover, director of hard coal and gas power plant U.K., RWE Generation. “Since then, the power industry has grown and evolved, with newer power plants—like our stations at Pembroke and Staythorpe—allowing for more efficient and reliable power generation.
“At RWE, we contemplated multiple operating scenarios for our Great Yarmouth plant. Ultimately, we decided to implement GE’s technologies and digital solutions to improve plant performance, output, efficiency and flexibility in a cost-effective manner.”
The modernizations GE will provide at the Great Yarmouth power station—a 400 MW combined-cycle power plant consisting of a GE 9F.03 gas turbine and a GE D10 steam turbine and generator—include a gas turbine upgrade as well as major inspections of the steam turbine and generator with replacements of key components in the steam turbine.
The upgrades also include GE’s Dry Low NOx 2.6+ combustion system, Advanced Gas Path solution, Asset Performance Management advanced digital solution, Mark VIe integrated control system and associated gas and steam turbine generator maintenance. With the upgrade, the plant’s combined-cycle efficiency will be increased by up to 2% and its output is expected to be improved by 21 MW, GE said.
“For the past 12 years, GE has supported RWE’s Great Yarmouth power station with innovative solutions. This latest upgrade builds on our collaborative history and helps improve the plant’s efficiency and flexibility, which, in turn, will increase the facility’s merit order in the U.K.,” said Michael Rechsteiner, vice president, GE’s Power Services business in Europe. “We will inject our advanced technologies in both the combustion and hot gas path sections and implement digital solutions to help RWE’s Great Yarmouth power station meet future U.K. energy consumption targets and emissions thresholds.”
RWE Generation owns, operates and maintains a portfolio of 8546 MW of gas, coal and biomass power stations in the U.K., including some smaller open-cycle gas turbine and combined heat and power generation assets. GE has active involvement across RWE’s U.K. plants, including at Aberthaw, Pembroke, Staythorpe, Little Barford and Great Yarmouth, which total approximately 6.5 gigawatts of installed capacity.
