Fluence Energy and Statkraft have delivered the battery energy storage project.

Additional information

The hybrid battery-and-wind project, which combines 11 MW of battery with 23 MW of onshore wind, will be fully operational in early 2020. The site is located on Statkraft’s first stand-alone Irish onshore wind project (link to Kilathmoy news item) since entering the Irish market, at Kilathmoy on the Limerick / Kerry border in the south-west of Ireland. Statkraft will enter a contract with EirGrid, thereby providing reserves to the national electricity grid in the event of a sudden drop-off in supply.
