Procurement of automatic Frequency Restoration Reserve (aFRR) in Q3/2018

The Nordic TSOs have decided to continue with procurement of a total volume up to 300 MW during weekdays (Monday to Friday) in Q3/2018 (July-September). The basis for the procurement is the targeted 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.

Nordic balancing moves forward

The work on a future Nordic balancing model continues forward and all five Nordic Transmission System Operators (TSOs) have agreed to a Memorandum of understanding. This paves the way towards the future balancing of the Nordic power system, including the introduction of modernized Area Control Error (ACE) as the balancing method. The aim of the TSOs is to have one common Nordic Load-Frequency (LFC) block, consisting of 11 LFC areas corresponding to the current bidding zones.
