Procurement of automatic Frequency Restoration Reserve (aFRR) in Q3/2021 (weeks 27-39)

The Nordic TSOs have decided to increase the current aFRR procurement with 10 hours on weekdays in Q3/2021. The total volume will be varied with approximately 300 MW in most hours and approximately 400 MW in morning hours during weekdays.

The basis for the procurement is the agreed goal for frequency quality level, and the TSOs will continue to procure aFRR in the hours where the system balancing is most challenging.

Starting from Monday 5 July 2021, aFRR will be procured as detailed below in Central European Time (CET):

The TSOs reassess the procurement scheme continuously based on the frequency quality, and possible changes in the procurement scheme will be informed in advance.

Information about the procurement for Q4/2021 will follow in September 2021.
