Kilroot power station is a fossil fuel power plant on the north shore of Belfast Lough at Kilroot near Carrickfergus in County Antrim, Northern Ireland. The plant currently has a 141 megawatt (MW) capacity from four standby gas turbines and a 10 MW battery energy storage capacity from the Kilroot Advancion Energy Storage Array.
When coal power generation stopped in September 2023, it was the only remaining coal-fired power station operating in Northern Ireland, and it had a 560 megawatt (MW) capacity from dual coal and oil fuelled generators. The station once produced a third of the country's electricity, and was also one of County Antrim's top 100 employers in 2010 (or before).
