Power grid operators around the world typically rely on running coal and natural gas fired power plants to maintain what is called spinning reserve, or excess capacity, that can respond quickly to provide gri.
Microsoft wants to replicate a battery-sharing arrangement it has tested at a Dublin data center in Ireland. The scheme, announced in 2022, uses a lithium-ion battery energy storage system (BESS) and a grid-interactive uninterruptible power supply (UPS) from Eaton to share energy with the local grid when needed.
How many wind farms are in Ireland?

(Image: Microsoft) Microsoft data centers will soon begin sharing energy from their battery storage systems with Ireland's power grid, a move designed to help bring more wind energy onto the grid in the energy-constrained Dublin region.
In a bid to support Irish grid stability, Electricity Supply Board (ESB) has opened a major battery plant at its Poolbeg site in Dublin, which will add 75MW/150MWh of fast-acting energy storage.
How will a battery-based energy storage system affect energy security in Ireland?
In addition, by participating in the capacity market, the project will have a positive impact on energy security in Ireland. This battery-based energy storage system is designed to provide 20MW for up to four hours. Most grid-scale batteries currently deployed in Ireland range from 30 minutes to two hours of energy storage capacity.
Where is Ireland's first grid-scale battery energy storage system based?
Statkraft has announced that it is to build Ireland's first four-hour grid-scale battery energy storage system (BESS) in Co. Offaly. The 20MW BESS, supplied by global market leader in utility-scale energy storage solutions and services, Fluence, will be co-located with Statkraft's 55.8MW Cushaling Wind Farm.
