Summary

Energiföretagen Sverige‘s process page for the FNA (Flexibility Needs Assessment / Flexibilitetsbehovsbedömning) work, covering the background, timeline, and Swedish national implementation. Documents the Energiföretagen-led task force and seven webinar series (June 2025 – March 2026) for coordinating DSO participation.

Key information

What the FNA is

  • FNA = Flexibility Needs Assessment (Flexibilitetsbehovsbedömning / Flexibilitetsbehovsanalys) — a mandatory biennial process requiring DSOs and TSOs to quantify and report their flexibility needs at national level
  • Established by ACER as secondary EU legislation applicable as national law in all Member States, published 25 July 2025 (ACER Decision 05-2025)
  • ENTSO-E + EU DSO Entity proposed the method; ACER revised and approved it
  • Two dimensions: system flexibility (balancing of production and demand) and network flexibility (managing bottlenecks and voltage problems)

Regulatory outputs the FNA enables

  1. National FNA report → submitted to ACER + European Commission (deadline July 2026)
  2. National indicative targets for non-fossil flexibility (deadline January 2027)
  3. EU-wide ACER report with gap analysis (deadline July 2027)
  4. Biennial repetition; linked to network development plans (same data and methods)

Swedish process timeline

  • Spring 2025: Energiföretagen launches task force for national implementation (DSO perspective)
  • Autumn 2025: Task force works with Svk to develop FNA method proposals, in dialogue with Ei
  • Seven webinars held June 2025 – March 2026 to engage all Swedish DSOs
  • 25 November 2025: National implementation agreement signed (Svk + DSO representatives + Ei) — see Source - FNA Överenskommelse Svenskt genomförande 2026 (2025)
  • Spring 2026: All DSOs report flexibility needs
  • July 2026: National FNA report submitted to ACER/Commission
  • 17 August 2026: Eighth webinar — review of FNA 2026 results and improvement proposals

Reporting obligation nuance

“Needs shall be reported by the one experiencing the constraint” — a lokalnät that is constrained by its subscription to the overlying regionnät reports the flexibility need, even if the root cause is a bottleneck in the overlying network. This separates the reporting obligation from the procurement obligation (which, per Source - Ei Ställningstagande Ei2025-01 Villkorade avtal (2025), rests with the operator whose network has the physical constraint).

Relevance to wiki

  • Confirms ACER Decision 05-2025 as a published piece of secondary legislation (July 2025); the NC DR framework is therefore already partially in force via this FNA methodology regulation
  • Energiföretagen’s active coordination role in FNA parallels their work in AG Helhet Flex on NC DR implementation — the same industry body coordinating both
  • Timeline context: FNA 2026 is happening now (April 2026) — an active, real process, not a future one
