ONE OF THE WORLD’S LARGEST HIGH-SPEED GAS ENGINE POWER PLANTS WILL PROVIDE 450 MW OF SCALABLE POWER IN THE UK

NNIO Group and Clarke Energy are helping to deliver one of the world’s largest high-speed gas engine peaking power plants in Thurrock, UK. The two companies already signed a contract to this effect in 2024. The 450-MW flexible generation facility is being constructed by Statera Energy, a leading developer, owner, and operator of flexible energy assets. With full operations targeted for late 2026, it is expected to provide enough power for up to 1 million homes in Southeast England—helping to support the UK’s energy resilience strategy.

   As the UK transitions to renewables, grid stability is more critical than ever. The Thurrock Flexible Generation Project is designed to respond rapidly to fluctuations in supply and demand, ensuring reliable electricity during peak periods and when renewable output varies. Located near London, the plant plays an important role in balancing the capital’s energy needs, supporting the UK’s secure, low-carbon future.

  “This project sets a new benchmark for grid flexibility in the UK. With scalable, reliable, and future-ready energy, we’re helping accelerate the UK’s shift toward a more resilient power infrastructure,” said Dr. Olaf Berlien, President & CEO of INNIO Group.

  Matt Arnold, Director of BESS & Flex-Gen at Statera Energy, stated: “Thurrock Power is a key milestone in Statera’s mission to deliver cost-effective flexibility at scale. As the UK’s largest flexible generation site, it will help balance the grid and support renewables. Clarke Energy and INNIO’s Jenbacher technology offer speed, fuel flexibility, and reliability – key for energy security in a decarbonizing system.”

  INNIO’s energy solution combines high electrical efficiency, rapid start-up in less than 5 minutes, and cost advantages over alternative technologies. Its scalable deployment allows for high efficiency at partial loads. This flexibility enables the plant to swiftly respond to fluctuations in electricity supply and demand. The Jenbacher “Ready for H2” engines in Thurrock will operate primarily on natural gas but are designed to run on a variety of fuel blends, including biomethane and hydrogen
