Accuracy

The track record

Average error as a share of installed capacity (nMAE), against Elia's published day-ahead forecast.

Average error by window

Uncertainty

How tight, and how reliable, the bands are

Share of days the actual output landed inside the 80% range, and how wide that range was. Tighter at the same coverage is better.

Daily detail

Every day, scored

Days marked pending are awaiting Elia's measured generation, which is published with a delay, so the most recent days settle one to two days later.

Method

Independent, transparent, measurable

Every morning, before the day-ahead market gate, OpenWindCast forecasts tomorrow's wind generation for the region: a central estimate in megawatts plus a calibrated 80% range, built from a multi-model weather ensemble. When the real generation is published, every day is scored automatically and added to the public record above.
