New rules will relax planning requirements for batteries of more than 50 megawatts (MW) in the U.K., Europe’s largest utility-scale battery storage market. New record-sized batteries will likely be launched in the next year or two as a result. Currently, several 50MW batteries in the U.K. jointly hold the European record for the largest battery. The new rules allow projects to receive planning permission in two to four months under local planning laws, rather than in one to two years under the Nationally Significant Infrastructure Projects (NSIP) regime.
