Wind power generation
Continuously tracking and forecasting wind power generation enables Elia to operate its grid smoothly around the clock.
Storm alert notification
1 Storm alert notification
Forecasting toolA notification is generated when the forecasting tool detects a Storm event in the North Sea in the next 36 hours. The total storm impact in terms of wind power generation drop and the timing of the storm are published.

3 Graph Legend
The forecast period always begins with the D Forecast (intraday data) and runs to the D+7 forecast (future data).
This is a snapshot of the D+7 forecast and is updated at 4.45 p.m. (with values created at 4.00 p.m.).
This is a snapshot of D+1 forecast and is updated at 05.40 p.m.
Most recent forecast
Offshore forecast is updated - at 1.00 am, 6.00 a.m., 10.00 a.m., 1.00 p.m., 6.00 p.m. and 10.00 p.m. (CE(S)T) in summer time and at 5.00 a.m., 9.00 a.m., 12.00 p.m. (midday)., 5.00 p.m., 9.00 p.m. and 11.55 p.m. in winter time Onshore forecast is updated every hour at around hh:05.
The unique quarter-hourly value for upscaled measurements is updated every quarter of an hour. The value is always the amount of power equivalent to the running average measured for that particular quarter-hour. These measurement data are always obtained from an estimate based on an extrapolation, since Elia does not have all the measurement data at its disposal.
Monitored capacityElia always tries to ensure that its forecasts and the corresponding measurements reflect the latest situation with regard to installed wind power capacity in the Belgian control area. However, it can only show forecasts and measurements for monitored capacity for which it has detailed background information.Depending on the filters selected, the monitored capacity displayed is shown in the graph alongside the filter buttons.
The percentage ratio between measured wind power generation in [MW] and total monitored wind power capacity in [MW].
Active decremental bids
This indicates whether wind power has been reduced following the activation of decremental bids on wind farms.
