When is AWS eu-central-1 greenest?
Carbon-aware scheduling · updated 2026-09-05 00:01 UTC
The AWS eu-central-1 region runs in Frankfurt, Germany, on the Germany electricity grid. educk forecasts when that grid is greenest — using day-ahead wind & solar and demand data from ENTSO-E — so you can schedule carbon-aware workloads (batch jobs, CI, model training, backups, data pipelines) for the cleanest hours.
- Wind and solar are forecast to cover about 88% of Germany's electricity demand around 00:15 UTC.
- Renewable output peaks around 12:15 UTC at roughly 137% of demand — the greenest time to use electricity today.
- The renewable share dips to about 71% around 20:00 UTC, when grid electricity is at its most carbon-intensive.
- There is forecast surplus renewable generation around 12:15 UTC — an ideal low-carbon window for flexible loads such as EV charging, laundry or heating.
