These reports summarize Great Britain electricity data by calendar month.

Each report includes average carbon intensity, average renewable share, and monthly fuel mix percentages.

Data sources: Carbon Intensity API (NESO and University of Oxford), Elexon BMRS, Sheffield Solar PVLive, and NESO embedded generation datasets.

Reports are generated automatically at the start of each month and can be refreshed if upstream datasets are revised.

Methodology is published on the About page.
