Data Shows 2025 Approvals for Renewable Energy Projects Reached Record Levels in Britain

Britain greenlit a historic number of renewable energy projects in 2025, with permissions nearly doubling compared to the previous year. Combined capacity for battery, wind, and solar installations that received approval reached 45GW, marking a 96 percent jump from 2024 figures, according to Cornwall Insight analysis. Battery storage led the charge, with permissions climbing to 28.6GW from 14.9GW the year prior.

Offshore wind projects saw even more explosive growth, surging more than sevenfold to 9.9GW from just 1.3GW. Across the past five years, authorizations for these three technologies have increased over 400 percent.

Energy Secretary Ed Miliband said his government is fulfilling its pledge to regain control of Britain’s energy future through domestic clean power. Each authorized project and investment aims to shield the country from unpredictable fossil fuel markets while protecting households and permanently reducing energy bills, he noted. The effort reverses years of delays and inadequate investment in the sector.

Robin Clarke from Cornwall Insight said the authorization surge demonstrates genuine momentum in Britain’s energy transformation. However, he cautioned that permissions alone don’t produce electricity. The urgent need now involves transitioning from plans to actual operational projects. Substantial capacity remains trapped in connection queues or awaiting infrastructure upgrades, he explained. Network bottlenecks pose one of the greatest threats to converting today’s permissions into functioning power generation.

Project launches have fallen behind the acceleration in authorizations, primarily due to lengthy construction periods and connection delays. Many developments sat stuck in a queue system based on application timing. Recent reforms eliminating inactive projects and prioritizing those ready for construction, most needed, and fastest to connect should help clear these obstacles and speed Britain’s renewable buildout.

Britain’s grid operator canceled hundreds of generation projects this month to eliminate a substantial backlog preventing construction-ready schemes from connecting. Over half the queued projects face removal, making room for approximately £40 billion ($53.8bn) worth of developments deemed most likely to help achieve the government’s virtually carbon-free electricity target by 2030.

Developers may have rushed to secure 2025 permissions before stricter connection rules take effect and before local elections potentially create uncertainty around future planning policies.

Clarke said recent reforms represent meaningful progress but won’t fix everything. Quicker decisions, increased infrastructure investment, and real cooperation among government, regulators and industry remain essential to fast-tracking green energy adoption, he noted. Without these components, record-breaking numbers risk becoming meaningless figures.

Rapidly expanding renewable capacity will require Britain to substantially reinforce and expand its electricity network, Cornwall Insight added, as existing infrastructure wasn’t built to handle such high volumes of variable generation and storage. Investment in flexibility, transmission improvements and smart technologies will be crucial for ensuring these projects deliver power where and when they are needed most.

As private-sector players like Turbo Energy S.A. (NASDAQ: TURB) expand their footprint in more international markets, the realization of renewable energy targets is likely to come closer to reality for many countries.
