Carbon and generation

Carbon intensity and generation context

Compare the next regional carbon-intensity forecast with Agile prices, then place it beside measured wind, estimated solar generation and declared curtailment. London is the initial display, not a guess at your location.

National generation context

These sources use national or different regional geographies. They add context and are not components of the selected GSP forecast.

Solar generation context

Every figure here is a model, not a meter reading. Almost all British solar sits on rooftops and small sites behind the distribution network, where nothing meters it centrally: PV_Live estimates the total by scaling a metered sample of sites up to the known installed capacity. It is the best national figure that exists and it is not a measurement.

The national figure is modelled separately from the regional ones and is not their total. Across the stored days the fourteen regions add to between 98.5% and 103.2% of it, so the regional figures may never be summed and presented as the national one.
