Schwerin Battery Park. Description. In order to store the excess wind energy in the region, the 5MW/5MWh battery park was installed in the city of Schwerin (Germany), consisting of 25,600 lithium manganese-oxide cells supplied by Younicos and Samsung SDI. In late 2016, WEMAG decided to enlarge their battery park.
Batteries help absorb electricity and reduce exports to the grid, and in the longer term, batteries are likely to play a significant role in helping the transition to 100 per cent renewable energy. Renew magazine discusses the chances of a renewable grid by 2030, and what role solar households play in the article 100% renewable grid.
