September 21 (Renewables Now) - Norwegian renewable power producer Statkraft AS unveiled today a plan to build a 20-MW grid-scale energy storage system in Ireland which will be the first four-hour battery in the country.
The battery energy storage system (BESS), supplied by US energy storage specialist Fluence Energy Inc (NASDAQ:FLNC), will be installed in County Offaly where it will be co-located with Statkraft’s 55.8-MW Cushaling wind farm, currently under construction.
Building works in relation to the battery project are expected to be finalised by late 2024. Upon completion, the energy storage facility will support the operations of state-owned electric power transmission company EirGrid.
Statkraft highlighted in the statement that most grid-scale batteries currently deployed in Ireland range from 30 minutes to two hours of energy storage capacity.
The Cushaling project is the third battery to be developed by the Norwegian firm in Ireland. The company’s other two batteries, also delivered by Fluence -- Kilathmoy in 2020, and Kelwin-2 in 2021, are located in County Kerry.
