Aggregate information for Belgium

Here, you can view information about the forecast [MW], measurement [MW] and monitored capacity [MWp] for a certain quarter-hour for the country as a whole. Under the date picker you will find information for the selected quarter of an hour for the country as a whole.
Colour legend

This is used to colour the regions based on their forecasted or measured load factor for each quarter hour.

Time interval

Quarter-hour
Forecast period

The forecast period always begins with the DForecast (intraday data) and runs to the D+7 forecast (future data).
Week-ahead forecast

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.).
Day-ahead forecast

This is a snapshot of D+1 forecast and is updated at 5.40 p.m. (with values created at 4.00 p.m.).
Most recent forecast

This forecast is updated every hour.
Measurement updates

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 capacity

Elia always tries to ensure that its forecasts and the corresponding measurements reflect the latest situation with regard to installed solar-PV power capacity in the Belgian control area. Installed capacities are displayed in MW-peak and are retrieved from data shared by regional authorities: Vlaams energie en klimaatagentschap (in Dutch) and Carte dynamique (solaire et éolien) de la Wallonie (in French)

Depending on the filters selected, the monitored capacity displayed is shown in the graph alongside the filter buttons.
Load factor

The percentage ratio between the upscaled measurement in [MW] and the monitored capacity in [MW].
