Flexible thermal generation will play a critical role in the transition to a low carbon economy and decarbonised electricity system, providing the reliable capacity at scale in response to market changes and events.
SSE has an ownership interest in five gas-fired power stations that participate in the GB electricity market and one in Ireland – all of which are among the most flexible on the GB and Irish electricity systems. It also retains interest in multi-fuel generation and one remaining coal-fired power station.
