German utility SWW Wunsiedel has ordered a large-scale battery storage system from engineering and technology giant Siemens, which will participate in weekly tenders to help balance the local grid.
News in brief: SolarEdge’s Powerwall-compatible StorEdge self-consumption solution is now available internationally; AES completes another 10MW project in Holland which will provide grid services; and Japan’s Sumitomo Corporation’s Willey Battery Utility is the latest energy storage system to join PJM’s frequency regulation market.
Steag, a major power generator which constructs, plans and operates power plants, is spending US$100 million on acquiring 90MW of large-scale energy storage to help stabilise Germany’s grid.
