Ei FNA Method Page (2025)

Title: Flexibilitetsbehov — FNA-metoden (Swedish; official regulatory guidance page). The published date (2025-11-15) is the date given in the raw clipping; content reflects the November 25, 2025 trilateral agreement.

Summary

Ei’s official guidance page for Swedish grid companies on the FNA methodology. Confirms the trilateral framework agreed by Svk, Energiföretagen Sverige, and Ei, and specifies reporting obligations and timeline for the 2026 cycle.

Key facts

ACER approval: The FNAM, developed by ENTSO-E and the EU DSO Entity under Regulation (EU) 2019/943, was approved by ACER on July 25, 2025 (the page links the methodology as ACER Decision 05-2025, Annex I). (ACER)

Swedish national framework: Svk, Energiföretagen Sverige, and Ei agreed on how to apply the FNAM in Sweden on November 25, 2025. The agreed framework is published on Energiföretagen’s website.

Reporting obligations — all elnätsföretag (region and local DSOs) must:

1. Respond to Svk’s survey on market and digitalization barriers (enkät) — deadline January 23, 2026
2. Submit a flexibility needs assessment using the agreed template (Bilaga 3 on Energiföretagen’s site) — deadline April 7, 2026

National report: Svk compiles Swedish DSO inputs into a national FNA report. After Ei approval, it is submitted to the EU Commission, ACER, and the Swedish government by July 25, 2026 (the page states the date only; it falls one year after ACER’s July 2025 approval).

Reporting cycle: Biennial from 2026 — all elnätsföretag assess their flexibility needs for the coming 5–10 years every two years.

Use of reports:

• Form the basis for national targets for non-fossil flexibility (the page cites no article; Art. 19f of Regulation 2024/1747 and its timing come from Source - Electricity Market Design Reform Regulation (EU 2024-1747), not this page)
• Used by ENTSO-E to update the Union-wide Network Development Plan (UNDP)
• May in time lead to the development of support systems for flexibility

Definition used: Flexibilitetsbehov = DSO’s need to modify or limit resources’ power injection or withdrawal. The page also describes flexibility need more broadly as the need to handle fluctuations, uncertainties and real-time changes.

Relevance to wiki

Confirms and extends content in Flexibility Need Assessment, particularly the Swedish implementation timeline. The April 7, 2026 DSO submission deadline has since passed; the page itself says nothing about what happened afterwards.
