The facility has the capacity to export up to 20 MW of electricity to the grid for nine hours. The synchronous condenser can mitigate frequency variations, improve system inertia and enhance grid stability, while the BESS can store surplus renewable energy and release it. Statkraft's Rory Griffin writes about the challenges and opportunities encountered in developing Ireland's first-ever 4-hour duration battery storage project, which is co-located with a wind farm. 39 of PV Tech Power, Solar. Supplied by Fluence, a global market leader in utility-scale energy storage solutions and services, the 20MW BESS will be co-located with the company's 55. 8MW Cushaling Wind Farm, which is also currently under construction. As in other countries, grid capacity in Ireland is becoming scarce. Taoiseach Micheal Martin at the ribbon cutting for Shannonbridge B alongside Nigel Reams, CEO of Lumcloon. Ireland and Northern Ireland share the Single Electricity Market (SEM), one of Europe's most wind-dependent grids. The Irish government targets 80% renewables by 2030, requiring 9 GW of onshore wind, 5 GW of offshore wind, and 8 GW of solar on an all-island system that currently peaks at around 6.
