A 100MW/200MWh BESS project in Northern Ireland has been acquired by the renewable energy development subsidiary of UK-headquartered power generator and developer SSE.

The 2-hour duration Derrymeen battery in Dungannon, County Tyrone was bought from developer Heron Energy and would be the largest installed BESS facility in Northern Ireland when online.

Subject to a final investment decision by SSE Renewables, the shovel-ready project will be constructed on a greenfield site located outside Coalisland, around five miles from Dungannon.

If approved for final delivery, construction could commence early next year and the BESS would be operational by the end of 2026. It will connect to the grid via an underground cable to the nearby existing Tamnamore substation.
