Switzerland's largest battery storage facility goes online

Axpo and Energie Uri inaugurated the Plattischachen battery site in the canton of Uri after construction began less than a year earlier. Axpo previously said its 50 MW system would provide two hours of storage, while Energie Uri’s 8.4 MW system will focus more on cantonal needs. The project gives Switzerland a larger flexibility asset as solar and wind output grow and as battery systems become more central to balancing European grids.
