NESO Historic Generation Mix
All electricity generation data comes from the National Energy System Operator's Historic Generation Mix dataset, which provides half-hourly readings aggregated to daily values.
Coverage
Data includes grid-connected generation only. Embedded generation (rooftop solar, small wind) may not be fully captured. Carbon intensity is calculated from the generation mix using standard emission factors.
