Wind speed is at 100 metres, averaged over the main wind farm areas; sunshine is solar radiation reaching the ground, averaged over southern and central England. The Agile price is Octopus Agile's import rate for the region picked at the top of the page (change it there). Every figure is also in the generation table below.

Average GW by source, with demand (including imports and storage) as a line.
About these figures
- Wholesale price is the Elexon market index for the half-hour, in pounds per megawatt-hour (£100/MWh is 10p per kWh). It isn't what you pay: Octopus Agile prices follow it, with network costs and VAT added.
- Demand is generation plus transfers (interconnectors and pumped storage). Solar and some wind are "embedded" in local networks and aren't metered live; those figures are National Energy System Operator estimates, revised over the following hours.
- Battery storage isn't counted, because only battery discharge is reported, so including it would count the same power twice.
- The past day, week, 30 days, 90 days and year are averages. All time goes back to a year before Wattly started recording live grid data in October 2026.
