Svk aFRR Q3 2026 Procurement (2026)

Title: Upphandling av automatisk frekvensåterställningsreserv (aFRR) för Q3 2026 (joint Nordic TSO note).

Summary

Joint Nordic TSO note setting the aFRR procurement schedule for Q3 2026 (from 1 July). The headline change: aFRR Up is reduced to 200 MW during hours 7–19 (06:00–19:00 CET) (the note says “from 2025 MW”, a typo; Svk’s July 2026 monthly report says the Nordic daytime up volume was cut by 25 MW, so the earlier level was 225 MW); aFRR Down is unchanged. Procurement basis is the TSOs’ frequency-quality targets, which stayed within target in early 2026; the schedule is re-evaluated continuously.

Key figures

• Total Nordic volumes (from 1 July 2026): aFRR Up 200–250 MW, aFRR Down 250–325 MW, procured every hour of every day.
• Hourly pattern (CET): Up = 250 MW at night (hours 1, 24) and 200 MW otherwise; Down = 300 MW (hours 1, 24), 250 MW (off-peak), and 325 MW during hours 7–19 (06:00–19:00 CET).
• Nordic TSO shares of the total volume:

(The note’s phrasing “från 2025 MW till 200 MW” is a typo. The prior daytime level is not stated; the schedule table itself shows 200 MW Up in every hour except 250 MW in hours 1 and 24. An earlier wiki inference that the previous daytime level was 250 MW was wrong: Svk’s July 2026 monthly report states the Nordic up volume was lowered by 25 MW in hours 07–19, i.e. from 225 MW (Source - Svk Månadsrapport Balansmarknader Juli 2026). The note’s PDF link is labelled Q2 2026.)

Key claims and observations

1. Daytime aFRR Up demand is being trimmed (to 200 MW, hours 7–19 = 06:00–19:00 CET); the note gives frequency quality holding within target in early 2026 as the main basis for procurement volumes. (The note does not state this as the explicit reason for the reduction.)
2. Svk carries the largest Nordic aFRR share (38–39%) of the four TSOs listed.
3. aFRR remains procured all hours, all days — distinct from the time-limited LFM products at distribution level.
4. Context for the PICASSO (aFRR European platform) connection at Q4 2027: aFRR demand is expected to step up to 120–350 MW after connection (per other wiki sources, not this note); this Q3 2026 schedule precedes that connection.

Relevance to wiki topics

Superseded from 1 October 2026 by the Q4 schedule (Source - Svk aFRR Q4 2026 Procurement (2026)): aFRR Down in hours 7–19 falls from 325 MW to 275 MW, Up unchanged.
