What’s powering Britain right now.

This page keeps an eye on Great Britain’s electricity grid. Every five minutes it collects the official figures: how much each kind of power station is producing, how much the country is using, what it costs on the wholesale market, the grid frequency, and how much power is moving through the undersea cables to Europe and Ireland. Nothing is thrown away, so the charts further down go back to the first day it started recording.

It’s an independent project and has no connection to NESO or Elexon. The map shows what each power station has told the grid it plans to generate this half-hour, which is usually close to what actually happens, but not always.

Where the numbers come from
Elexon, NESO and Sheffield Solar, all published openly
How often it updates

      p/kWh, half-hourly

      The average price electricity traded at on the wholesale market for each half-hour (Elexon market index). It leaves out network charges, policy costs, supplier margins and VAT, which is why household tariffs are much higher.
