A review of Britain's electricity generation over the past four years, including the contributing energy sources, carbon intensity, proportion of zero-carbon sources and further insights.

In December 2024, wind energy accounted for the highest proportion of Britain’s electricity mix among all energy types, contributing 39%. Gas contributed 29%, which was a 3% increase from December 2023. Although wind's contribution was higher than in December 2021 and 2022, it was 2% below the 41% recorded in December 2023. Imports reached their highest level for December in the past four years, supplying 10% of Britain’s electricity mix, which is 3% more than in December 2023. Contributions from biomass, hydro, solar and storage remained stable compared to December 2023, providing 6%, 3%, 1% and 1%, respectively. Nuclear energy saw a 2% decrease in its contributions, delivering 12% of the mix in December 2024, the lowest level for December in the past four years. Coal contributed 0% after its phaseout from Britain's electricity generation in September of the previous year. Zero-carbon sources comprised 56% of Britain's electricity generation, marking the second highest level for December in the last four years; however, 4% lower than for December in the previous year. Despite this decline, the rolling 12-month average for zero-carbon sources was 51%, the highest of the last four years. The carbon intensity of electricity generation in December 2024 was 126 gCO₂/kWh, representing a 3% increase compared to December of the previous year. However, the rolling 12-month average was 125 gCO₂/kWh, indicating a 17% reduction compared to the previous 12-months and the lowest level in four years, reflecting ongoing decarbonisation efforts. Increasing electricity generation from renewable sources is essential for achieving our net-zero goals, ensuring energy security, and reducing reliance on imports.

In November 2024, gas was Britain's primary electricity source, accounting for 38% of the mix, a 7% increase from November 2023. Wind energy contributed 27%, 4% lower than the previous year, marking its lowest November share in four years. Nuclear, biomass, solar, and hydro maintained their contributions from 2023 at 12%, 7%, 2%, and 2%, respectively. Nuclear's share was 4% below November 2021, the lowest in four years. Coal contributed 0% after the closure of the last coal-fired power plant, Ratcliffe, in September, while imports provided 11%, the second-highest November level in four years. Zero-carbon sources made up 42% of Britain's electricity generation, the lowest for November in four years and 5% lower than last year. However, the rolling 12-month average for zero-carbon sources is 51%, the highest in the same period. The carbon intensity of electricity generation in November 2024 was 171 gCO₂/kWh, an increase of 6% from November in the previous year. The rolling 12-month average dropped to 124 gCO₂/kWh, marking a 21% reduction and the lowest level in four years, reflecting ongoing decarbonization efforts. Increasing the electricity generation from renewable sources can help achieve our net-zero ambitions, ensure energy security, and decrease reliance on imports.

edenseven are following trends in the renewable energy sector closely, as decarbonising the energy sector is vital for ensuring a sustainable future and achieving Net Zero. Considering the recent DESNZ quarterly update of the renewable energy planning database, we have produced a consolidated summary of projects in the United Kingdom that have received planning permission. We will continue to release updates each quarter. INSIGHT In the past 12 months, the UK granted planning permission for 668 solar PV projects, which will deliver over 3,800 MW of energy capacity. This represents the second-highest number of solar projects approved in a year on a quarterly rolling basis. Additionally, these projects will provide the third-highest energy capacity for Solar PV granted planning permission in the UK in the last 15 years. However, this capacity is 20% lower than that of the 994 projects approved in the preceding year. During the same period, the number of onshore wind projects granted planning permission in the UK increased by 50%, while the number of approved offshore wind projects remained stable compared to the prior 12 months. When considering all solar PV, onshore, and offshore wind projects, granted planning permission in the UK over the past 12 months, the total energy capacity declined by 36% compared to the prior 12 months. Offshore wind saw the sharpest decline, with energy capacity from approved projects falling by 62%, while onshore wind also decreased significantly. Despite the total decline, the average energy capacity of approved solar PV projects rose by 20% year-on-year, highlighting an increase in the size of solar PV projects receiving planning permission in the UK. In contrast, both onshore and offshore wind projects experienced declines in average project capacity—down 51% and 62%, respectively.

In October 2024, wind was the leading source of electricity generation in Britain, accounting for 31% of the electricity mix. Despite this, wind’s contribution was the lowest for any October in the past four years, down 3% from October 2023 and 5% from October 2022. Gas followed closely, contributing 30% to the electricity mix, which, while its second-lowest for October in the past four years, was still 3% higher than in October 2023. Biomass contributions increased by 2%, reaching 8% of the mix, the highest for October in the past four years. Solar energy provided 4% of the mix, up 1% from October 2023. Nuclear and hydro both saw a 1% decrease in their contributions, delivering 13% and 2% of the electricity mix, respectively. Imports remained steady, contributing 11%, the same as in October 2023. October 2024 was notable for having zero coal in Britain’s electricity generation, following the closure of the Ratcliffe power plant, the UK’s last coal-fired station. This is a significant achievement, considering coal has provided electricity in the UK for over 140 years and accounted for nearly 40% of the UK’s electricity generation in 2012. Zero-carbon sources made up 51% of Britain’s electricity generation in October 2024, the lowest for any October in the past four years, but only 1% below the rolling 12-month average of 52%. The carbon intensity of electricity generation in October 2024 was 138gCO₂/kWh, consistent with October 2023. The rolling 12-month average carbon intensity of 123gCO₂/kWh is 22% lower than the previous 12-month period, marking the lowest level in the past four years as the grid continues to decarbonise. Increasing the electricity generation from renewable sources can help achieve our net-zero ambitions, ensure energy security, and decrease reliance on imports.
