Normalized offshore wind energy in Belgium, year 2016

Homepage Forecast data 2017 2015 Solar Onshore wind Summary Load percentages

This page shows daily plots of forecast grid data for offshore wind energy in Belgium, year 2016. 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. Therefore values normalized to kWh/day per kWpeak, and also hourly fluctuations are provided. In general grid forecast data is more accurate than weather re-analysis from satellite data.

Average hourly data:
The plots below show hourly data, normalized to kiloWatt per installed capacity expressed in kiloWatt peak. The Elia grid data contains four data points per hour, these are averaged to represent a single hour on the plot. So the hour 14 combines data points from 14:00, 14:15, 14:30 and 14:45 for example. In the legend we display the avarage daily generated energy in kWhpeak per month. The maximum achievable energy per day is 24 kWh per kWpeak of installed capacity, since there are 24 hours in a day. Fluctuations are summarized with boxplots for the entire year and per month.
