Instavolt opens five battery storage sites, plans 20 more by end of 2026 to cut grid costs

By Eve

Instavolt has commissioned five new battery energy storage system (BESS) sites, each costing approximately £500,000, bringing its total battery-equipped locations to eight. The charge point operator plans at least 20 additional BESS sites before the end of 2026, with confirmed locations including Wisbech, Knutsford, Cheltenham, Blyth, Stockton-on-Tees, Penrith, York, and Thirsk. CEO Delvin Lane said the batteries charge overnight when energy is cheaper and cleaner, with stored power used during expensive daytime hours to pass savings to drivers.

Why it matters

Battery storage allows CPOs to bypass grid connection delays and reduce exposure to peak electricity costs, making rapid charging hub deployment faster and more economically viable. The £500,000 per site investment signals a strategic shift toward on-site energy management as a competitive differentiator in the UK charging market.

InstaVolt opens 16 ultra-rapid chargers at Serpentine Green in Peterborough

InstaVolt has launched a 16-bay ultra-rapid charging hub at Serpentine Green Shopping Centre in Hampton, Peterborough, near Junction 17 of the A1. The site includes four fully accessible bays and four dual-connector chargers offering both CCS and CHAdeMO connections, all powered by 100% renewable energy and available 24/7. InstaVolt App users pay 55p per kWh between 8pm and 7am.

Why it matters

The hub adds significant ultra-rapid capacity in a high-footfall retail location with strong road links, demonstrating continued rollout momentum for InstaVolt. The inclusion of accessible bays and dual-connector units reflects procurement priorities around inclusivity and vehicle compatibility in public charging infrastructure.

750 affordable homes in UK now heated by mine water geothermal network

A new energy centre at Seaham Garden Village in the UK is now supplying low carbon heat to around 750 affordable homes using naturally warm mine water pumped from a Durham treatment facility. Energy Live News reported that the network has completed commissioning and is fully operational. The system uses geothermal processes that keep mine water at a relatively constant temperature year round, providing a dependable heat source instead of traditional heating fuel.

Why it matters

The operational mine water heating network demonstrates a replicable model for decarbonising heat in social housing developments, potentially informing procurement specifications for low carbon heating infrastructure at scale. The proven reliability of geothermal mine water as a consistent year round heat source may influence future district heating tenders and public sector energy resilience planning.

Tesla Powerwall autonomously grid-charged before peak rates to offset low solar yield in Arizona

A Tesla Powerwall owner in Tucson, Arizona, reported that the battery began charging from the grid at around 2:30 p.m. on a rainy day, ahead of a 3 to 7 p.m. peak rate window, after solar generation fell short. The homeowner had set the system to Saving mode and disabled Stormwatch, allowing the Powerwall to draw enough grid power to cover the high cost period. The case, shared on Reddit's r/Powerwall forum, illustrates how residential storage can automatically balance low renewable output with time of use tariffs.

Why it matters

The example shows demand side flexibility in action, with home batteries responding to tariff signals and weather conditions without manual intervention. For CPOs and utilities, it underscores the growing role of behind the meter storage in load shifting and the need for rate structures that reward or integrate such behaviour at scale.
