Renewable share of generation
What it measures
The share of an hour's electricity generation that came from renewable fuels, as a percentage, tracked alongside carbon intensity.
Inputs
- ENTSO-E actual generation per production type for the bidding zone selected on the view, hourly
Method and weighting
The renewable share of generation is the total hourly output of wind (onshore and offshore), solar, hydro, biomass, geothermal and other renewables divided by the total hourly output of every fuel, expressed as a percentage. Both totals are read from the same hour of the canonical hourly grid. An hour with no positive generation from any fuel is dropped. Across the window, a higher share tends to sit beside a lower production-based carbon intensity, because more of that hour's generation came from a low-emission fuel.

Known limits
- The share counts generation only, so imports play no part in it.
