- Elexon metered generation by fuel, half-hourly (FUELHH).
- Solar: Carbon Intensity API share applied to metered total.
- Embedded wind (typically 1 to 4 GW) is not in Elexon's metered data, so totals run slightly low.
Carbon intensity
g/kWh, same period.
- Carbon Intensity API, measured values where available.
