UK company Pivot Power is to build a £25m grid-scale battery that it says “will pave the way for an electric vehicle charging superhub” in northwest England.

The company has been given planning permission to install a 50MW battery at Harker electricity sub-station in Carlisle, which Pivot expects to be operational by October 2019.

It will be one of the UK’s biggest batteries, storing enough electricity to supply nearly 6000 average homes for a day from a single charge.

Currently, the UK has in the region of 500MW of grid-scale battery storage. Pivot has an overall £1.6bn scheme to install its technology at 45 sites across the UK. At each site, it will combine 50MW batteries with rapid charging stations. Pivot aims to have 10 sites operational within 18 months and 45 within five years. Carlisle will be the second site, after Southampton was named as the first in July.

Pivot says the development “will put Carlisle at the forefront of the smart energy revolution, creating infrastructure that will make it easier for drivers to switch to EVs and that will support action to clean up the region’s air”.

The company plans to locate the EV charging ‘superhub’ at a nearby site, which could offer rapid charging for up to 100 cars at once and be capable of supporting the fastest chargers.

It will also be able to support mass charging infrastructure for commercial fleets such as electric buses, taxis and vans.

Pivot’s chief technology officer Mikey Clarke said: “The plan will contribute to cleaning our nation’s air and driving forward a cleaner greener economy – a need brought into sharp focus by the UN Intergovernmental Panel on Climate Change’s landmark climate scenario report last week. Working with the local authorities, our plans will see Carlisle become a pioneering city for low carbon vehicle adoption, ensuring that the rural areas it serves are not left lagging in the EV revolution.”
