Live Generation, Demand and Carbon

Generation, Demand, Carbon & Price — Yesterday/Today

Generation mix for Great Britain since midnight yesterday. Use Sources, GW/%, Mix/Type and 1d/2d to change the view; the legend and table toggle series and show averages, share and cumulative GWh (hover for each half-hour).

Battery is national BESS discharge (derived physical output from PN plus balancing actions, not metered). The same amount is removed from Misc (OTHER) so it isn't double-counted. State of charge isn't published.

Charts below show carbon intensity at point of generation, demand, and the APX wholesale index price (£/MWh) with traded volume — not household tariffs.

Updates every 30 minutes. Historical data back to 2009 is on the historical page.
