Ireland T-4 capacity auction results confirmed

12 Mar 2021

The results of the latest T-4 Capacity Auction in Ireland have now been confirmed by the Regulatory Authorities, with SSE Thermal securing contracts for all units that participated.

In total, SSE Thermal has secured contracts for 570MW of de-rated electricity generation capacity for the delivery year 2024/25. This includes our Great Island CCGT station in Co. Wexford (383MW) and two smaller peaker plants at Rhode in Co. Offaly (93MW) and Tawnaghmore in Co. Mayo (94MW).

Through this latest T-4 auction, the System Operators have provisionally awarded a total of 6,168MW of capacity contracts to electricity generators and demand side response units at an auction clearing price of €47,820/MW.

SSE Thermal’s other plant in Ireland, Tarbert Power Station in Co. Kerry, will be required to close by the end of 2023 in line with emissions regulations, and therefore did not participate in this auction process.
