UK secures £1.3B in battery storage and clean power investments from French and Indian firms at G7. The pledges close a wide gap between current capacity and 2030 targets.
British Prime Minister Keir Starmer announced £1.3 billion ($1.74 billion) in investment commitments from French and Indian companies at the G7 summit on Tuesday. The pledges are earmarked for battery storage and clean power projects, the government said, though it did not name the specific firms involved or break down the total by country.
The round comes as Starmer's administration pushes its clean-energy agenda ahead of the next general election. The UK targets 50 GW of offshore wind capacity by 2030 and roughly 30 GW of battery storage over the same period. Installed battery capacity today sits around 4.5 GW. Closing that gap requires private capital on a scale that these pledges, if converted to actual projects, would help address.
French firms have focused historically on offshore wind supply chains and grid interconnection technology, while Indian companies have invested more in battery storage and solar-linked infrastructure. The government offered no new subsidy mechanisms or tax breaks alongside the announcement. The UK's Contracts for Difference regime and the capacity market remain the primary revenue support structures for new energy projects.
For battery storage developers, the business case depends on the arbitrage spread between low-price charging hours and high-price discharge windows. That spread has narrowed in recent quarters as more storage capacity has come online. The fresh investment commitments suggest the companies involved expect the spread to stabilize or widen again as coal-fired plants retire and renewable penetration increases.
Starmer's team framed the G7 round as evidence that international investors see the UK as a stable destination for energy infrastructure capital, even as the government's fiscal headroom tightens and planning reform proceeds slowly. The Treasury did not introduce new incentives. The conversion rate of these pledges to actual construction will matter more than the headline number.
The government said further details on individual projects and timelines would be published in the coming weeks.
