Svk Tarifföversyn Ny Tariffmodell (2026)

Svenska kraftnät’s documents on its tariff review (tarifföversyn): the project page, the memo Översyn av transmissionsnätstariffen: förslag till förändringar i modellen (Svk 2023/2237, version 1, dated 19 February 2026, 37 pages), the summary of consultation responses (11 December 2025, Dnr 2025/4677), the annex on the voltage-regulation power component (dated 31 March 2026) and the one-page overview of the model from 2027. The prices actually set for 2027 are in Source - Svk Transmissionsnätsavgift 2027 (2026); the synthesis is Transmission Network Charge. The memo is a proposal document, so where the decided 2027 levels differ (the overrun fee, the 2027 size of the power fee) the price list and FAQ prevail. The voltage annex (34 pages) is summarised only at the level of its design, examples and weighting factor.

Why and when

• Ei’s regulation EIFS 2022:1 on the design of grid tariffs had to be applied by 1 January 2027 and, together with the EU rule on tariffs (Art. 18 of Regulation 2019/943), shaped Svk’s review. The regulation requires a tariff of four components (energy fee, customer-specific fee, power fee, fixed fee) based on four cost categories (short-term variable, customer-specific, forward-looking, residual costs); Ei can grant a dispensation.
• Government and Ei, 2026: in March 2026 the government told Ei to repeal EIFS 2022:1, and to propose a new model for the design of power-based fees by 12 April 2027 (project page). See Source - Ei Konsekvensutredning EIFS 2022-1 Upphävande (2026).
• Process: a reference group met from May 2023 to December 2025 (members: Ellevio, Energiföretagen, Ei, E.ON Energidistribution, Fortum, Jämtkraft, Neoen, Svensk vindenergi, Skellefteåkraft, Statkraft, Sydkraft Hydropower, Vattenfall and Vattenfall Eldistribution). The proposal went to consultation on 1 September 2025 (answers to 15 October; 14 respondents named as such, 15 listed in the footnote); a webinar followed on 7 October 2025. The board decided the model on 19 February 2026.

The model component by component (memo)

• Overrun fee as proposed: the charge for the first four quarter-hours reduced by 50% (the “allowance” shortened from eight to four); no charge between applying for a temporary subscription and Svk’s answer; from 2028 a dispensation must be applied for within 24 hours after an overrun caused by redistribution or an accepted regulation bid. The price list for 2027 sets the levels at 500 and 1,400 SEK/MW per quarter-hour, which do not follow the memo’s “50%” wording.
• Energy-storage category: several respondents asked for one so that storage does not pay for both injection and withdrawal; Svk plans a storage customer category for 2028, to be designed with the reference group. Svk says no point is expected to be charged a power fee in both directions, so there is no double charging in the power fee.
• Sum subscriptions: kept. All existing sum subscriptions end on 31 December 2026; customers must reapply for 2027. The earlier criterion that an increase must have been refused at every point falls away, because a subscription cannot be below the agreed power. New criteria: written connection agreements; same price area, limited geographical area and same customer; similar effect on limiting elements; no limiting elements between the points in an intact grid; electrical connection via regional lines (a time-limited exception to the last point). Svk will move to an annual follow-up rather than annual application after 2027.

Consultation responses (December 2025)

• Customer-specific fee: positive or neutral; clarification that abonnemangspunkt equals the former anslutningspunkt.
• Energy fee: divided, with injection customers mainly negative to the distribution factor (more complex, less predictable) and others positive; Svk made no change.
• Power fee, grid expansion: mostly negative, especially for injection (asymmetry, complexity, yearly changes, transparency). Svk’s changes: tie it to the ten-year grid development plan, calculate from a lower ambient temperature, consider moving the injection high-load period to summer, and use hourly values because most regional grid companies do. Injection customers are expected at 0 SEK/kW for 2027.
• Voltage regulation: positive, especially to remuneration, which was seen as too low; complexity and the risk of gaming the settlement were raised. Svk postponed it to 2028, will review the level and the weighting (the consulted 0.75 was to be raised slightly; the memo uses 0.85), and keeps it voluntary. Svk is working with the five largest regional grid owners on a “UQ agreement” collecting the voltage and reactive-power requirements; “near-zero” reactive exchange is generally ±30 Mvar at 400 kV and ±15 Mvar at 220 kV.
• Subscription fee: Ei refused Svk’s dispensation application for a separate subscription fee; its parts were moved into the fixed fee.
• Fixed fee: respondents disagreed on how residual costs are split between injection and withdrawal. Svk lowered injection’s share of the cost burden from 50% to 45% for 2027 because the voltage remuneration was postponed.
• Overall: respondents found the model more complex (Svk: largely because Ei’s regulation requires four components against today’s two), wanted congestion income kept reducing the tariff (Svk agrees, for a stepwise return to full cost coverage), and wanted national guidelines for applying the model across grid levels (referred to Ei). Svk says targeted support belongs in separate, transparent support systems, not in the tariff.

Consequences (memo, chapter 6)

• The distribution factor, on 2026 figures, raises the energy fee in the north and lowers it in the south, moving cost from withdrawal to injection customers; the stepwise introduction keeps its effect under 10%.
• The fixed fee: because a subscription can no longer be below the agreed power, about 3,000 MW of capacity could be freed if those customers lower their connection-agreement power; if they raise subscriptions instead, the fixed fee falls by about 6%.
• The geographic differentiation is expected to shrink: the tariff falls for injection customers in the north and withdrawal customers in the south, and rises for injection in the south and withdrawal in the north; the equal cost-covering part lowers the tariff for all withdrawal customers and raises it for all injection customers on 2026 figures; both moves are limited by the stepwise introduction.
• The memo says the old power fee is reduced by “about 80%” with congestion income and that Svk plans to begin raising the tariff in 2027, stepwise over a number of years if Ei approves further use of congestion income.
