Renewable Generation Records Fall Across the UK, as Imported Gas Consumption Tumbles

Why It Matters

The shift reduces the UK’s reliance on costly imported gas and accelerates progress toward net‑zero, while putting downward pressure on electricity prices.

Key Takeaways

• Renewable electricity share hit 52.5% in 2025, a new record
• Imported energy fell to 46% of primary supply, lowest since 2004
• Wind generation peaked at 23,880 MW, covering 60% of GB electricity
• Solar output reached 14,414 MW, powering 11 million homes
• Gas-fired plants dropped to 2.3% of grid, reducing fossil reliance

Pulse Analysis

The United Kingdom is accelerating its shift away from fossil fuels, as the latest Energy and Climate Intelligence Unit analysis shows renewable sources now supply more than half of the nation’s electricity. In 2025, renewable generation accounted for 52.5 percent of total output, up from 51 percent the previous year, while imported primary energy fell to 46 percent—the lowest share since 2004. This trend reflects both the rapid expansion of wind and solar capacity and the continued decline of North Sea gas production, even after decades of extraction‑maximising policies.

Wind power set a new peak of 23,880 megawatts on March 25, delivering roughly 60 percent of Great Britain’s electricity and enough to run over 23 million homes. Solar generation followed suit, breaking back‑to‑back records in early April with a maximum of 14,414 megawatts, sufficient for 11 million households and representing 35 percent of consumption at that moment. As renewable output surges, gas‑fired plants were reduced to just 2.3 percent of the grid mix, a level that translates into lower wholesale electricity prices and reduced exposure to volatile gas markets.

The momentum behind wind and solar is expected to deepen as sunnier weather patterns and continued investment drive further capacity additions. Analysts anticipate that higher renewable penetration will compress price spikes, improve grid resilience, and enable the UK to meet its legally binding net‑zero target without relying on costly imported gas. For investors, the data signals expanding opportunities in clean‑energy infrastructure, storage solutions, and demand‑response technologies. Policymakers, meanwhile, must ensure that transmission networks keep pace with generation growth to safeguard the reliability gains achieved this year.
