UK Power Dashboard

A live UK power dashboard showing the current electricity generation mix, 24-hour generation trend, grid demand and monthly system frequency.

The dashboard uses National Grid ESO and NESO data, cached locally to reduce load. It is useful for seeing how much of the grid is currently coming from gas, wind, nuclear, solar, imports and other sources, alongside current demand and frequency behaviour.

System Frequency may take several seconds to render.
