Study on the integration of offshore wind in the Belgian balancing zone

A significant increase of the offshore wind production is expected up to 2020 in the Belgian offshore area. Once all offshore parks will be fully operational the total installed capacity will increase to 2300 MW. The unexpected variations in wind farms power production due to high wind speed (also defined as “storm event”) or sudden changes in wind power or direction (also defined as “ramping event”) might at that time trigger substantial imbalances in the Belgian control area. Furthermore, because all Belgian offshore wind parks are situated close to each other in the North Sea, it has been observed that they all behave in a similar way facing a storm or ramping event and that impact will mainly differ because of wind turbine technical characteristics.

To better understand the possible impact of storm and ramping event on the Belgian control area, ELIA has finished a study with support of the consultant 3E. This document presents the results of the statistical assessment realized on observed events in 2015 and 2016, the extrapolation towards installed capacity in 2020 and formulates recommendations. The potential integration of offshore wind beyond 2300 MW has not been assessed and will require a new study.
