Världens största batteripark kan försörja 200 000 invånare med elektricitet

I staden Dalian i nordöstra Kina, med drygt sex miljoner invånare, kopplades världens största batteripark till elnätet i torsdags. Målsättningen är att balansera elnätet och säkra hushållens tillgång till elektricitet samt att testa batterilagring i stor skala. För att kunna leverera elektricitet oberoende av väderförhållanden och klockslag behövs en infrastruktur för energilagring.

This battery can serve 200,000 residents during peak times of energy use.
