EV charging network InstaVolt has announced the opening of five new battery storage sites, which it says will help future-proof its charging hubs against rising grid costs and connection delays.
The five sites, each representing an investment of approximately £500,000, bring the total number of battery-equipped InstaVolt locations to eight. At least 20 further sites are planned before the end of 2026, with additional locations across Wisbech, Knutsford, Cheltenham, Blyth, Stockton-on-Tees, Penrith, York, and Thirsk already confirmed for the following financial year.
Delvin Lane, CEO, InstaVolt, said: “Battery storage is one of the most powerful tools we have for accelerating the switch to electric. It lets us deploy faster, manage our costs more effectively, and pass genuine savings on to drivers. Our batteries charge overnight when energy is cheaper and cleaner, and we draw on that stored power during the more expensive daytime hours. That saving goes to the consumer.”
The programme addresses two structural pressures that are intensifying across the public charging sector: escalating network demand charges, which increase in line with peak power draw, and grid connection delays that are holding back deployment of the rapid charging infrastructure the UK needs.
By integrating on-site battery storage, InstaVolt says its sites can draw power from stored reserves during peak charging periods, reducing exposure to demand tariffs and meaningfully increasing the total power available to drivers at any given moment. Sites can also open on smaller initial grid connections, with battery capacity compensating for the gap, cutting deployment timelines significantly.
The five sites are:
Hadfer Ltd at Bwch Moch Cafe (opened March 2026)
National Co-op at 311 Lower Addiscombe Road (opened March 2026)
Burney Group at Harwich 2 (opened April 2026)
BNP Paribas at Northampton Williams Way (opened April 2026)
Three Trees Farm Shop and Cafe (opened April 2026).
The company also said its Winchester Superhub is also supplemented by on-site solar. In March it said 91% of all energy sold was delivered during peak hours between 7am and 8pm, even though 89% of energy purchased from the grid was during off-peak hours and stored in the batteries.
