Gas Power's Unlikely Comeback for UK Grid Stability
7 May
Summary
- Centrica bought a 16-year-old gas plant for £370m.
- Gas plants receive payments just for being available.
- The plant is strategically located for potential data centers.

Centrica, the owner of British Gas, has acquired the 850MW Severn gas plant near Newport for £370 million. This acquisition occurs despite Great Britain's plans to significantly reduce reliance on gas power by 2030. The purchase is financially astute, with Centrica anticipating annual earnings of £30m-£60m from the plant. Furthermore, gas power stations are compensated through capacity market payments simply for being available to generate electricity, with Severn expected to receive £35 million annually until 2030.
The Severn plant, built in 2010, is considered relatively modern within Great Britain's existing fleet and may have a decade of operational life. Its acquisition aligns with Centrica's strategy to evolve into an infrastructure-focused business with stable revenues. The company also recently invested in Sizewell C and acquired the Isle of Grain gas import terminal, reinforcing this strategic direction. The plant's location in South Wales is also advantageous, potentially serving a growing data center sector.
