California home batteries deliver record 745 MW to grid in Sunrun and Tesla virtual power plant
By Eve
Residential battery systems operated by Sunrun and Tesla supplied 745 MW of power to the California grid on 6 October, setting a new US record for distributed residential energy resources. The previous record of 669 MW had been set just one day earlier. Thousands of home batteries discharged stored solar energy during evening peak demand hours, functioning as a coordinated virtual power plant at the request of distribution utilities.
Why it matters
The deployment demonstrates how aggregated home storage can provide grid services at utility scale, potentially reducing the need for centralised peaking infrastructure. For charge point operators and energy managers, it signals growing competition for evening grid capacity and highlights the role of distributed assets in balancing renewable intermittency.

Grid connection costs and electricity prices delay electric truck rollout, report warns
A report from the Aldersgate Group and Renewable Energy Association finds that grid connection costs, electricity prices and financing barriers are slowing the UK's electric truck transition. Zero emission vehicles make up just 0.3% of the HGV fleet and 1.1% of new registrations in Q3 2026, despite diesel prices exceeding £2 per litre for the first time in October. The report calls for a unified government transition plan covering long term frameworks, risk reducing finance and infrastructure planned ahead of demand.
Why it matters
Grid connection costs and electricity pricing directly affect the business case for depot charging infrastructure that CPOs and fleet operators must build to support electric truck adoption. With HGVs accounting for 17% of UK transport emissions but minimal electrification to date, addressing these barriers could unlock significant charging infrastructure procurement opportunities.
WeaveGrid launches managed EV charging programme with North Carolina electric cooperatives
Grid-edge orchestration software provider WeaveGrid has launched EVConnectNC, a managed EV charging programme for electric cooperatives in North Carolina, developed in partnership with North Carolina Electric Cooperatives. The programme uses connected vehicle and charger data to analyse EV charging patterns and encourage members to shift charging to lower cost, off-peak times. Two cooperatives, South River EMC and Roanoke Electric Cooperative, are already enrolled and paying out incentives.
Why it matters
The programme demonstrates how software platforms can enable smaller, member-owned utilities to deploy demand management incentives without building in-house capabilities. For charge point operators and grid service providers, it shows a scalable model for partnering with cooperatives to manage load and reduce infrastructure costs.

Commercial vehicle to grid charging could unlock emerging energy resource, says Versinetic study
Electric vehicles could become a significant source of distributed energy storage to manage peak demand and support renewable electricity, according to research by smart EV charging consultancy Versinetic. The study, authored by EV analyst Julian Skidmore, examines vehicle to grid technology development across the UK, Australia, Germany, France, the Netherlands, Norway, the US and Japan. After almost 30 years of research and trials, vehicle to grid is moving towards commercial deployment, with regulatory progress, greater interoperability and emerging business models beginning to support wider adoption.
Why it matters
The shift from trials to commercial vehicle to grid deployment creates new revenue opportunities for charge point operators and fleet managers who can monetise EV batteries as grid assets. Regulatory progress and interoperability improvements signal that procurement specifications may soon need to account for bidirectional charging capability in commercial charging infrastructure.
