LONDON, United Kingdom (February 9, 2026) – GE Vernova Inc. (NYSE: GEV) has successfully completed a major modernization and outage project at InterGen’s 800-megawatt Coryton combined cycle power station, located on the River Thames east of London. The project included the installation of two High Efficiency (HE) upgrades on GT26 gas turbines, delivering results that exceeded initial performance expectations.

According to InterGen, the upgraded units achieved stronger-than-anticipated improvements in both efficiency and power generation. Daniel Fosberg, Managing Director at InterGen, praised GE Vernova’s service teams for their execution and highlighted the company’s broader strategy of investing in flexible generation assets to support grid stability as renewable energy capacity continues to expand across the UK.

GE Vernova’s HE upgrade integrates advancements in turbine, compressor, and combustor technologies. At Coryton, the modernization increased plant output by up to 85 MW—well above the projected 77 MW gain—while also improving efficiency by 2.46%. The enhanced performance is expected to deliver substantial fuel savings and reduce annual carbon emissions by approximately 67,500 tonnes, supporting the UK’s efforts to lower the carbon intensity of electricity generation.

The outage scope covered a wide range of maintenance and inspection activities, including borescope inspections on generators and steam turbines, electrical testing, and valve inspections. More than 300 GE Vernova specialists from engineering, manufacturing, logistics, field services, sourcing, and project management collaborated with InterGen throughout the process. Together, the teams completed over 122,000 working hours without a single recordable environmental, health, or safety incident.

Joseph Anis, President and CEO of GE Vernova’s Gas Power business for Europe, the Middle East, and Africa, stated that the project demonstrates the company’s ability to deliver complex modernization programs that improve both operational performance and long-term competitiveness. He also noted that GT26 turbines are capable of operating with hydrogen-natural gas blends, offering future opportunities for further emissions reductions.

The Coryton project marks another milestone for the GT26 HE platform. By 2025, eleven GT26 units equipped with HE upgrades had already entered operation globally. Introduced in 2019, the HE upgrade combines technologies from GE Vernova’s F-Class and H-Class turbine fleets, including additive manufacturing innovations and advances in aerodynamics, combustion, and materials engineering. The result is a substantial improvement in efficiency, output capability, and maintenance intervals.
