Ireland gets new large-scale battery storage


IrelandStatkraft has completed the construction of its second large-scale battery project in Ireland, the Kelwin-2 26MW project.

The Norwegian utility entered a contract with EirGrid and has started providing reserves to the national electricity grid in the event of a sudden drop-off in supply.

Battery purpose

The main purpose of the battery is not to store bulk wind generation but to respond instantly to the electrical frequency fluctuations that result from increasing amounts of intermittent power generation. Similar to Statkraft’s 11MW Kilathmoy project which began operation in April 2020, Kelwin-2 is also a hybrid site where the battery shares a grid connection with a wind farm.
