In May 2026, we announced the successful commissioning of Hirwaun Power Station, our first OCGT plant. Hirwaun, which is located in South Wales, is the first of three 299MW OCGT plants which we’re developing in England and Wales.
The second and third sites are expected to commence commissioning in 2026, which is later than originally planned, primarily due to delays in grid connection by the relevant authorities.
The three OCGTs combined will provide capacity of c.900MW when fully commissioned and be remunerated via a combination of peak power generation, system support services, and long-term index-linked Capacity Market agreements. These Capacity Market agreements extend to 2039 and are worth over £260 million in revenue.
