educk tracks how much of Bulgaria's electricity demand is met by wind and solar generation, using day-ahead forecasts from the ENTSO-E transparency platform. Use it to plan flexible energy use — charging an EV, running appliances or batteries — for when the grid is cleanest.
- Wind and solar are forecast to cover about 17% of Bulgaria's electricity demand around 15:00 UTC.
- Renewable output peaks around 09:00 UTC at roughly 106% of demand — the greenest time to use electricity today.
- The renewable share dips to about 0% around 02:00 UTC, when grid electricity is at its most carbon-intensive.
- There is forecast surplus renewable generation around 09:00 UTC — an ideal low-carbon window for flexible loads such as EV charging, laundry or heating.
