What the average figure for energy production supplies to the grid was for (a) gas, (b) solar farms, (c) wind farms, (d) hydro-electric schemes, (e) nuclear, (f) biomass and (g) interconnectors for the last 12 months for which figures are available.
Figures for the historic electricity generation mix supplied to the grid in Great Britain are available on NESO’s data portal. The Department also publishes quarterly data on the total electricity supply in the UK by fuel in Energy Trends Table 5.1. This includes production from major power producers and other generators (mainly combined heat and power plants serving industrial and other users). As these data include electricity generated and consumed on-site, coverage is broader than electricity supplied to the grid.
