History
Demand, generation, price, emissions, transfers and the generation mix - every time period, side by side. The Season tab always shows the current UK meteorological season to date (right now, that is this season), not a fixed rolling window. Every chart's underlying data can be copied to the clipboard for use elsewhere.

From Open-Meteo, for a single representative GB point (roughly central England) - not a national average, and not tied to conditions at any specific wind farm. Shown for context alongside the charts above, e.g. to see whether a generation or price swing lines up with a windy or calm spell.
