​Great Britain set a new record for solar power generation on 1 April, with output reaching 12.2 gigawatts between 12:30 and 1pm, according to the National Energy System Operator (NESO).

The figure marks the highest level of solar generation ever recorded in the country, surpassing previous records and contributing significantly to the nation's low-carbon electricity supply during the afternoon period.

NESO described the milestone as an important step on the path towards operating a zero-carbon electricity system for short periods in 2025. The achievement reflects ongoing investment in renewable infrastructure alongside improved weather conditions for solar production.

The growth in solar capacity across the UK has continued steadily, with domestic and commercial installations playing a vital role in reducing dependence on fossil fuels. Analysts point out that every additional solar panel contributes to greater energy independence by decreasing the need for gas imports.

They also note that an increase in renewable energy sources such as solar and wind will likely reduce exposure to global energy price fluctuations. Since the energy crisis began, surging gas prices have added an estimated £140 billion in extra costs to the UK economy. Renewable sources, by contrast, offer a stable and often lower-cost alternative.

While solar power usually peaks in the spring and summer months, this record early in the season suggests strong potential for further highs as the year progresses. The UK's ongoing shift towards renewable electricity generation is part of wider efforts to meet net zero targets and improve long-term energy resilience.

The record-setting moment follows a broader trend of decreasing reliance on fossil fuels, with renewables playing an increasingly dominant role in the national grid. NESO continues to monitor generation patterns as the UK moves towards a more sustainable energy future.
