Background

Originally built as a coal plant in 1954, Connah's Quay now functions as a 1500 MW gas-fired power plant.[5] In 2021 the project applied for 750 MW existing generation (units 3 and 4, 375 MW each) in the T-4 Capacity Market 2024-2025 auction, and they were listed in the final results.[6][7] This would qualify them for government subsidies to guarantee electricity supply.[8] In the same auction, refurbishing units 1 and 2 (750 MW) was included.In 2021 Uniper is also floating ideas to develop a hydrogen hub at this facility.[5]
