Procurement of automatic Frequency Restoration Reserve (aFRR) in Q4/2021 (weeks 40-52)
The Nordic TSOs have decided to increase the current aFRR procurement with 6 hours during weekends (hour 11-13) and to increase volume on down-regulation in weekday evenings (hour 22-24) in Q4/2021. The total volume will be varied with approximately 300 MW in most hours and approximately 400 MW in morning hours during weekdays. In the late evening hours, down-regulation is also approximately 400 MW.
Starting from Monday 4 October 2021, aFRR will be procured as detailed 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 Q1/2022 will follow in December 2021.
