This page shows daily and monthly plots of forecast grid data for solar and wind energy in Belgium, year 2018, as a percentage of the total electricity load. We use quarter hour forecast data from Elia, which is corrected with up-scaled measurement data for the monitored capacity. The monitored capacity can deviate from the installed capacity; and it can change over time. Values are expessed as percentage of total daily or monthly load, and can fluctuate during different parts of a day. In general grid forecast data is more accurate than weather re-analysis from satellite data.
