Procurement of automatic Frequency Restoration Reserve (aFRR) in Q4/2018

The Nordic TSOs have decided to continue with procurement of a total volume up to 300 MW during weekdays (Monday to Friday) in Q4/2018 (October-December).

The basis for the procurement is the agreed goal for frequency quality level, and the TSOs will continue to procure aFRR in the morning and evening hours where the frequency variations are most challenging. An evaluation will be done for each quarter of the year.

The procurement schedule until week 39 will follow the earlier published information. From Monday 1 October 2018, aFRR will be procured in the following hours:

  • weeks 40-52, morning hours 4:00-8:00 (CET), evening hours 19:00-23:00 (CET)

Information about the procurement for Q1/2019 will follow in December.

The Nordic TSOs have further agreed on a plan to increase aFRR procurement in order to prepare for the new Nordic balancing concept and implementation of ACE (see previous information Plan to increase automatic Frequency Restoration Reserve (aFRR)).
