- Wind and solar generation both saw a 1% increase from September 2022 and delivered the highest proportion of Britain's electricity mix for September since 2021.
- Whilst gas decreased by 11% compared to September 2022, imported energy rose by 8% to its highest proportion for September since 2021.
- Zero carbon sources accounted for 49% of the generation mix, the highest for September in the previous three years.
- As a result, the carbon intensity for September 2023 was the lowest for September in the previous three years at gCO₂/kWh.
- The rolling 12-month average carbon intensity for October 2022 to September 2023 was the lowest for previous three years at 158gCO₂/kWh.
- Increasing the electricity generation delivered by renewables can help us achieve Net-Zero ambitions, ensure energy security and decrease reliance on imports.
