The UK has just cleared more renewable energy projects than ever before, marking a milestone in the country’s push to decarbonise its electricity supply. In the second quarter of 2025, more than 16.1 gigawatts of new renewable capacity were granted planning permission across 323 separate projects. According to analysis by the Financial Times, that figure represents a 195% increase compared with the same period last year, and is being hailed as evidence of growing momentum behind the government’s pledge to make 95% of Britain’s power carbon-free by 2030.
The sheer scale of approvals is striking. Among the projects moving forward are some of the UK’s largest planned offshore wind farms, alongside a wave of solar developments and battery storage sites designed to stabilise supply when the sun isn’t shining and the wind isn’t blowing. More than half of the capacity approved this quarter comes from battery schemes alone, an area that is quickly becoming as central to the transition as the turbines themselves.
The numbers are encouraging for a government that has staked a great deal on expanding clean energy. Labour’s manifesto pledge to deliver a near carbon-free grid by 2030 was ambitious, and critics questioned whether planning bottlenecks and slow approval processes would hold it back. These new figures show that, at least on paper, the system is beginning to accelerate.
Yet the reality is more complicated. Securing planning permission is only the first step. The greater challenge is connecting these projects to the grid, which remains hampered by outdated infrastructure and lengthy queues. Some developers warn they face waits stretching into the early 2030s before they can plug their projects in, raising fears that approvals could become little more than paperwork without major investment in the grid itself.
Approvals give us a real sense of power
The government has acknowledged this bottleneck and promised reform. Ofgem, the energy regulator, has already begun shifting away from the old “first come, first served” model to a “first ready, first connected” system, which should give priority to projects that are genuinely prepared to break ground. Ministers have also pointed to the creation of Great British Energy, a publicly backed body tasked with partnering private developers to build large-scale clean power projects. Together with the Clean Power 2030 Action Plan, these measures are intended to make sure the new approvals translate into actual generating capacity within the next five years.
The financial picture is also improving. Battery storage revenues reached record highs earlier this year, making investment more attractive, while costs for wind and solar continue to fall. Analysts say that combination of stronger economics and political support is drawing more capital into the sector than at any point in the past decade. If the momentum can be sustained, the UK could begin to outpace many of its European neighbours in terms of added capacity, reversing the perception that it had fallen behind.
Still, challenges remain. Large-scale infrastructure projects almost inevitably face opposition from local communities. In parts of Lincolnshire, residents have been vocal in opposing pylons and solar farms, describing them as scars on the landscape. Legal challenges can delay projects for years, and without careful engagement, the government risks a backlash that could slow the transition. There is also the question of cost. National Grid has said it will need to spend tens of billions of pounds to modernise the system, a bill that could ultimately add to household energy costs. Convincing the public that the long-term benefits outweigh the short-term expenses will be key.
The government is betting that the economic upside—thousands of new jobs in construction, engineering, and maintenance, as well as greater energy security—will outweigh the criticism. Reducing reliance on imported fossil fuels has taken on fresh urgency after years of price volatility, and officials argue that an accelerated shift to home-grown renewable power is the only way to protect consumers from future shocks.
The spike in approvals shows how quickly the political and investment landscape can shift when there is pressure to deliver. However, unless grid connections are accelerated and community concerns addressed, the gulf between what is approved and what is actually built may remain wide.
What is clear is that the UK has crossed an important threshold. With 16.1 gigawatts of clean power now approved in a single quarter, the ambition of a carbon-free grid by 2030 no longer looks like a distant dream. The challenge is to make sure those projects are more than just plans on paper, and that the electricity they promise flows into homes and businesses before the decade is out.
