Title: Ei inleder tillsyn av elnätsavgifter Publisher: Energimarknadsinspektionen (Ei) Published: 2026-04-09 URL: https://ei.se/om-oss/nyheter/2026/2026-04-09-ei-inleder-tillsyn-av-elnatsavgifter Language: Swedish

Short news article announcing the opening of a formal supervisory investigation (tillsyn) into effektavgifter (capacity charges) design at five named Swedish DSOs. Runs parallel to Ei’s government assignment to repeal EIFS 2022:1.

Key claims

Scope: Ei is investigating whether five DSOs’ effektavgift designs comply with ellagen and the Electricity Market Regulation (Art. 18). The five companies selected:

1. Bergs Tingslags Elektriska AB
2. Ellevio AB
3. Göteborg Energi Nät AB
4. Södra Hallands ekonomiska förening
5. Tekniska verken Linköping Nät AB

Selected partly based on customer complaints received, partly to achieve variation in company size and geography.

What Ei will examine:

• How DSOs describe the grid conditions relevant to their tariff model design
• How the tariff is structured and what considerations underlie the model
• Whether the model meets requirements for objective, non-discriminatory, and reasonable terms (ellagen), and for transparency and cost-reflectivity (Regulation Art. 18)
• Whether the tariff design is compatible with efficient grid use
• How tariffs are communicated to customers

Legal standard: Ellagen requires power transfer terms to be objective, non-discriminatory, and reasonable, and tariffs designed compatibly with efficient grid use. Electricity Market Regulation Art. 18 requires tariffs to reflect actual costs and be transparent.

Key clarification on legal status of effektavgifter: “Det finns inget krav varken i ellagen eller elmarknadsförordningen på att elnätsföretag ska införa en effektavgift som en del av elnätsavgiften. Samtidigt finns det inte heller något generellt förbud mot att använda en effektavgift.” — No requirement to have an effektavgift; no general prohibition either. It is the design of the tariff model as a whole — and its relationship to the regulatory requirements — that is subject to Ei’s scrutiny.

Context — simultaneous EIFS 2022:1 repeal: This tillsyn runs in parallel with Ei’s government assignment to (a) repeal EIFS 2022:1 (which had mandated all DSOs to introduce an effektavgift by January 2027) by 30 June 2026, and (b) develop a proposal for a new effektavgift model by 12 April 2027. The government assignment came in March 2026. Ei has confirmed that effektavgifter remain permissible even after the repeal of the mandatory obligation.
