A 135 MWh battery just plugged into Germany's grid — so sunshine can work the night shift

Solar power's oldest problem is timing: the sun clocks off before the evening peak. In Germany, a new 135 megawatt-hour battery storage project from Jinko ESS has entered service alongside a solar plant, built to catch surplus sunshine and release it when it's needed. The engineering is in the details: the system converts power with 94.1% efficiency, and its mirrored cabinet layout trims the site's footprint by 17.7% and halves the DC cabling — which means storage can be installed faster, on less land, next to the panels it serves. 'By bringing together PV, storage and a hybrid power purchase structure, this project reflects the kind of integrated approach that will make renewable energy more flexible and dependable,' said Roberto Murgioni, Jinko ESS's general manager for Europe.
