Pivot Power has won planning permission to build a £25 million 20MW battery at Nursling electricity sub-station in Southampton. It is the first of 45 sites across the UK where the company intends to site 50MW batteries.
Construction is expected to start around March 2019 and take three months.
Pivot Power will build the battery on a 1.6 acre plot on National Grid land and inside its secure perimeter. It will be housed in 25 containers, surrounded and concealed by a security fence and a 3m high wooden fence.
The site at Station Road is close to Junction 3 of the M27, and the company is in the process of identifying a site for an EV charging superhub, which will share the same grid connection as the battery. This will be the subject of a separate planning application.
