Microsoft is entering into a 15-year power purchase agreement (PPA) with GE to purchase 100 per cent of the wind energy from its new, 37MW Tullahennel wind farm in County Kerry, Ireland.
In addition to producing energy, the project will produce valuable data on energy storage. Each turbine will have an integrated battery; Microsoft and GE will test how these batteries can be used to capture and store excess energy, and then provide it back to the grid as needed. This will be the first deployment of battery integration into wind turbines to store energy in Europe.
