Public consultation on the study on procurement strategies for a dynamic calculation of FRR means

Context

In line with Article 228 of the Belgian Federal Grid Code, Elia determines the dimensioning rules for Frequency Restoration Reserves or ‘FRR’ (also referred to as aFRR and mFRR). The last years, Elia focused on the implementation of dynamic dimensioning methodologies, i.e. calculating the reserve capacity needs for the next day based on the expected system risks. 

With this study, Elia is widening the scope to the calculation of the volumes of balancing means to cover the reserve capacity needs. Up to now, these were covered by means of a ‘static’ calculation of the available non-contracted balancing energy bids, reserve sharing and balancing capacity. While the methodology currently in place meets all legal requirements, Elia investigates with this study the possibility of implementing a dynamic calculation of the contribution of non-contracted balancing energy bids in the determination of balancing capacity requirements. This study is the second step in an implementation roadmap presented in 2021, after the predictably of non-contracted balancing energy bids for the next day was demonstrated. 

Note that the study is complemented with an annex containing the full study of the consultant Compass Lexecon, including the detailed analyses of different procurement strategies, as well as the conclusions of the workshops with market parties.  This annex is attached for information but is not the subject of the consultation.
