InterGen Enlists GE Vernova to Modernize Coryton Power Plant

Published on: 

GE’s upgrade is set to boost the power capacity and efficiency of two GT26 gas turbines at InterGen's Coryton power plant.

InterGen has granted a contract to GE Vernova's Gas Power business for the modernization of its Coryton Power Plant. This enhancement project, slated for implementation in 2025, involves the installation of GE’s upgrade to two GT26 gas turbines. Located 30 miles east of London on the River Thames, the Coryton Power Plant boasts an 800 MW combined-cycle capacity.

Incorporating advancements from GE’s H-Class and F-Class fleets, along with additive manufactured parts and aerodynamic innovations, the upgrade aims to boost the plant’s power capacity by an estimated 77 MW. Beyond increasing power, the upgrade will enhance efficiency, extend maintenance intervals, and result in annual carbon emissions reduction of approximately 67,500 tonnes.

"At InterGen we continue to invest in the energy transition by boosting flexible generation to ensure the stability of grids as renewable generation increases, while developing advanced solutions that keep the lights on, at a manageable cost for our customers,” said Jim Lightfoot, InterGen's CEO: “We see GE as a reliable player and technological innovator to drive these goals forward. We selected GE’s HE upgrade because of its excellent part load efficiency and its fuel-flexible combustion system. With this innovative upgrade, we expect that our power station will benefit from improved efficiency and increased output, in line with our goals.”


“Once installed in 2025, this project will mark our 10th HE upgrade and our customers including InterGen continue to reap the benefits from this advanced upgrade for the GT26 fleet,” said Joseph Anis, President & CEO, Europe, Middle East & Africa at GE Gas Power.
