Svk 2026 — Balancing Market Outlook 2030, data update (published June 2026 based on Q4 2025 / early 2026 data). Svenska kraftnät’s annual update to the Balancing Market Outlook 2030, providing current pre-qualification volumes, price data, and revised outlook for each ancillary service product. This is a data update to the 2024 edition (Source - Svk Balancing Market Outlook 2030 (2024)); the structural narrative chapters are unchanged.

Document metadata

• Publisher: Svenska kraftnät
• Series: Balancing Market Outlook 2030 (annual data update)
• Base publication year: 2024; this update covers 2025 data / Q4 2025 snapshot
• Scope: All Nordic ancillary service products (FCR-N, FCR-D up/down, FFR, aFRR, mFRR) with Swedish focus
• Status: Market information publication; no regulatory decision

Key structural development: flow-based + 15-minute MTU

The 2026 update names a new primary challenge: the interaction between flow-based market coupling and the 15-minute market time unit (MTU). Flow-based coupling increases day-ahead trading volumes by allocating more cross-zonal capacity (CZC) to spot markets. This leaves less CZC available for balancing markets. Combined with the 15-minute resolution of the day-ahead market (shorter than the traditional 60-minute trading intervals), this creates reduced available transmission capacity in the balancing timeframe — making local reserves more critical and the design of the ACE-based balancing model more complex. This is described as the main new operational challenge for the Nordic balancing market.

Pre-qualification data: Q4 2025 snapshot

FCR-N (frequency containment reserve, normal operation)

• Swedish sharing: 37.75% from 2026 (up from prior level; fixed Nordic allocation key)
• May 2026 spot price: FCR-N 22.0 EUR/MW

FCR-D upward (frequency containment reserve, disturbance, upward)

• BESS is the dominant and fastest-growing technology in FCR-D up
• May 2026 spot price: FCR-D up 4.2 EUR/MW
• Static FCR-D upward limit: September 2026 — a fixed component (50% of total FCR-D up requirement) will replace part of the current dynamic allocation. Remaining 50% continues as dynamic (rotational energy share). This limits BESS dominance by reserving capacity for inertia-providing units.

FCR-D downward

• May 2026 price: 3.2 EUR/MW
• BESS significant contributor; hydro dominant

FFR (fast frequency response)

• FFR D-1 market (day-ahead procurement) expected 2028 — IT platform development 2027
• Currently procured D-7 (week-ahead) or contract; D-1 will improve price efficiency

aFRR (automatic frequency restoration reserve)

• PICASSO connection target: Q4 2027 for Svk — Energinet connected October 2024, Fingrid March 2025
• PICASSO introduces ACE-based aFRR energy activation — imbalance price will change from mFRR-only to joint mFRR + aFRR basis
• New BSPs will be able to connect to aFRR market when Svk joins PICASSO
• Supply is abundant; demand will grow significantly post-PICASSO as ACE-based balancing increases aFRR usage

mFRR (manual frequency restoration reserve)

• mFRR EAM (automated Nordic energy market): live March 2025
• ACE-based balancing: mFRR now dispatched to reduce area imbalance toward zero, not just frequency deviation
• Nordic MMS migration: completed April 14, 2026 — FCR moved to the new Nordic Market Management System
• MARI (European mFRR EAM): Nordic TSOs plan to connect Q1 2027 — as of April 2026, 13 countries connected
• Capacity demand expected to increase further as ACE-based model matures
• Local mFRR activations increasing due to flow-based coupling reducing available CZC for balancing

Market dynamics and outlook

Price trends

General trend: prices falling across most products as supply (especially BESS) grows faster than demand. Notable:

• FCR prices have fallen significantly compared to 2021–2023 highs
• Seasonal variation remains (higher winter)
• aFRR CM prices vary by bidding zone due to transmission constraints
• May 2026 aFRR CM prices: SE1 16.3 / SE2 17.1 / SE3 17.2 / SE4 15.2 EUR/MW

Volume growth

Total procured volumes have grown +273% since 2021 across all products combined. BESS is the primary driver.

BESS dominance

BESS is now the dominant and fastest-growing technology across every ancillary service product:

• FFR: 56% of pre-qualified volume is BESS
• FCR-D up: BESS is majority of total
• FCR-N: +280% growth in BESS volumes since 2024
• aFRR: BESS an emerging participant; PICASSO connection will unlock further demand

Balancing model review

Svk has initiated a comprehensive review of the Nordic balancing model — covering reserve dimensioning methodology, incentive structures, and the interaction between the ACE-based model and reserve requirements. This is described as a new strategic initiative. No timeline yet published for conclusions.

Regulatory calendar items

• September 2026: Static FCR-D upward limit introduced
• Q4 2027: Svk connects to PICASSO (aFRR EAM)
• 2027: FFR D-1 IT platform development
• 2028: FFR D-1 market operational
• Q1 2027: Nordic TSOs connect to MARI (European mFRR EAM)

Relevance to existing wiki topics

• Balancing Markets — Updated pre-qualification volumes, PICASSO timeline, static FCR-D limit, mFRR EAM live, MARI timeline, flow-based + MTU challenge, comprehensive model review.
• The Swedish BESS Business Case — Revenue Stacking and the FCR Saturation Problem — BESS dominant across all products; prices falling; PICASSO aFRR as new revenue avenue post-2027.
• Nordic Balancing Model — PICASSO status (Energinet/Fingrid connected; Svk Q4 2027), ACE-based aFRR post-PICASSO, comprehensive balancing model review, MARI Nordic connection Q1 2027.
• Svenska kraftnät — Nordic MMS April 14, PICASSO target, comprehensive balancing model review initiative.
• FFR — 910 MW pre-qualified; BESS +510 MW since 2024; D-1 market coming 2028.
