What the feed gives you

Two forecasts, one feed

System-imbalance direction in MW and the Ausgleichsenergie price in EUR/MWh, aligned per quarter-hour.

15-minute resolution

Horizons from T-15 and T-1h to D-1, each value carrying its forecast time and lead time.

Scored on realized data

Every forecast is benchmarked against realized Swissgrid outcomes; the best-scoring model is the one that serves.

Built for machines

Stable JSON and CSV, typed error codes, and a request_id on every response.

How it works
