Overview
InterGen’s plant 30 miles east of London along the River Thames generates 800 megawatts (MW) of power each year but is seeking to modernize its two GT26 turbines with performance enhancements.
Once the upgrades are installed in 2025, the plant is expected to produce 77 additional megawatts of power, gain added efficiency, and reduce carbon emissions by approximately 67,500 tons because less fuel will be required to produce the same amount of energy.

GE’s HE upgrade can help increase the output, efficiency, flexibility, lifespan, and availability of the two GT26 gas turbines installed at Coryton, while reducing fuel consumption and environmental impact. Additionally, these turbines are highly flexible and able to operate on a variety of fuels, including blends of hydrogen and natural gas, to offer InterGen pathways to reduce carbon emissions in the next decade.

“GE’s HE upgrade can help increase the output, efficiency, flexibility, lifespan, and availability of the two GT26 gas turbines installed at Coryton, while reducing fuel consumption and environmental impact. Additionally, these turbines are highly flexible and able to operate on a variety of fuels, including blends of hydrogen and natural gas, to offer InterGen pathways to reduce carbon emissions in the next decade.”
The result is an increase in power output and efficiency and a reduction in carbon emissions.

The upgrade combines the best from GE Vernova’s F- and H-Class fleets with additive manufactured parts and innovations in aerodynamics, material science and combustion dynamics.
GE Vernova’s Gas Power business had the solution: The GT26 high efficiency (HE) gas turbine upgrade.
UK power producer InterGen needed to modernize its two GT26 turbines to reduce emissions and increase output and efficiency.
InterGen, one of the largest independent power producers in the United Kingdom, has ordered GE High Efficiency upgrades to help modernize its Coryton Power Plant 30 miles east of London. The 800 megawatt (MW) combined cycle power plant uses two GT26 gas turbines that will be upgraded in 2025.
The upgrade, first introduced in 2019, combines the best from GE’s F- and H-Class fleets with additive manufactured parts and innovations in aerodynamics, material science and combustion dynamics. The result is an increase in power output and efficiency and a reduction in carbon emissions. Once the upgrades are installed, Coryton Power Plant is expected to deliver 77 additional MW of power and reduce its carbon emissions by more than 67,000 tons a year.
This will enable the power company to move toward its energy transition goals and stabilize the power grid while keeping costs down for customers. InterGen CEO Jim Lightfood has said the utility chose the GE upgrade because of its part load efficiency and fuel-flexible combustion system, which will help in reducing carbon emissions.
