When is electricity greenest in Romania?
Renewable energy forecast · updated 2026-10-03 08:36 UTC
educk tracks how much of Romania'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 96% of Romania's electricity demand around 08:45 UTC.
- Renewable output peaks around 09:15 UTC at roughly 100% of demand — the greenest time to use electricity today.
- The renewable share dips to about 2% around 19:00 UTC, when grid electricity is at its most carbon-intensive.
- There is forecast surplus renewable generation around 09:15 UTC — an ideal low-carbon window for flexible loads such as EV charging, laundry or heating.
