Transmission Network Charge

The transmission network charge (transmissionsnätsavgiften, until 2026 called transmissionsnätstariffen) is what customers connected directly to Svenska kraftnät‘s 400 and 220 kV network pay to use it. Payers are the grid companies and producers with a subscription point on the network; households and firms on local grids pay only indirectly, through their grid company’s costs (Source - Svk Transmissionsnätsavgift 2027 (2026)). It is a point charge: the price is the same whoever the counterparty is, and a subscriber gets access to the whole market. The charge covers operation, maintenance, depreciation and capital costs of the network and the electricity bought to cover network losses.

This is a different charge from the BRP fees Svk also sets (Source - Svk Avgifter Balansansvariga Parter (2026)) and from the grid companies’ own tariffs downstream (see Elnätsavgift — What Determines Your Bill and Swedish DSO Tariff Reform — Three Parallel Tracks (2025–2027)).

Phase-in

The 2027 step in numbers

• Fixed fee: Svk cuts the congestion-income reduction of the old power fee by about 350 MSEK, which Svk says raises the fee by about 20% on average (about 37% for injection and 14% for withdrawal); outcomes vary widely by point. A comparison of the price lists made for this wiki (153 points, unweighted) gives +36% for injection and +14% for withdrawal, which matches.
• Energy fee: 2027 reduced by 80% of each customer’s 2025 energy fee, about 2 bn SEK, paid from congestion income; the 2026 reduction was the same share of the 2024 fee (2.5 bn SEK paid in 2024). The marginal-loss coefficients rise about 5% on average.
• Total: Svk cites fee revenue after reduction of about 2.6 bn SEK (web page) or just under 2.5 bn SEK (FAQ), about 1.9 öre/kWh or 0.8% of an end customer’s electricity cost; without the reduction the tariff would be far higher (Svk’s 2026 estimate: about 9% of the grid bill instead of 1–2%). Svk’s news item and FAQ put the total 2027 reduction at over 8.3 bn SEK (over 2 bn off the energy fee, over 6.3 bn off the fixed fee); Ei’s congestion-income decision has ~6.8 GSEK, see Flaskhalsinkomster.
• Who gains and loses (before electricity prices): injection in the north pays more in energy fee; injection in the south and withdrawal in the north are credited more; withdrawal in the south pays less. The geographic spread of the fixed fee is expected to shrink while the cost-covering part is equal for all points and both directions.

Why congestion income matters

Congestion income arises from price differences between bidding zones and is mainly for capacity between zones, but Art. 19 of Regulation 2019/943 lets a surplus reduce tariffs. Svk has reduced the transmission charge this way since 2021, and in 2023 cut the old power fee by 60% (Svk FAQ). As Svk’s investments grow the room for reduction shrinks, so from 2027 the reduction of the fixed fee is stepped down toward full cost coverage to avoid large one-year jumps. Every use of congestion income for tariff reduction must be approved by Ei and decided by Svk’s board. In September 2026 the government asked Svk to report by 14 January 2027, for 2027–2031, how much congestion income is needed each year for the priority objectives and for a tariff reduction that counters large sudden rises, how much is left as a surplus, and what else the surplus could be used for (Source - Regeringen Uppdrag Svk Flaskhalsinkomster Överskott (2026)). See Flaskhalsinkomster.

Why four components

Ei‘s regulation EIFS 2022:1 told network companies to divide costs into short-term variable, customer-specific, forward-looking and residual costs and to use a tariff of four components (energy fee, customer-specific fee, power fee, fixed fee). Svk says that is why the model has a customer-specific fee although it is a tiny part of costs, and a power fee although it is 0 SEK/kW in 2027 (the forward-looking costs a customer can influence in the short term are negligible). Svk designed the energy fee and the fixed fee the same way regardless of the regulation. The government told Ei in March 2026 to repeal EIFS 2022:1, and Svk says it will consider whether the power component should stay. Ei refused a dispensation Svk applied for, to have a separate subscription fee, so its parts went into the fixed fee. See Source - Ei Konsekvensutredning EIFS 2022-1 Upphävande (2026).

Power fee design (in the model, zero for 2027)

The grid-expansion power fee is charged only in a high-load period (1 December–31 March, weekdays 07:00–10:59 and 16:00–19:59), on the mean of the three highest hours of a month on different days, and not in hours where the day-ahead price is at or below zero. The level comes from market-simulation runs over 35 weather years and is tied to lines that the ten-year network development plan says will be reinforced; radial lines and lines between price areas (covered by congestion income) are excluded. Consultation respondents were mostly negative, especially for injection, where high demand usually means the system needs more production; Svk lowered its ambient-temperature assumption and expects injection customers at zero in 2027. Svk noted the signal should line up with day-ahead prices so end customers do not get conflicting signals. (Source - Svk Tarifföversyn Ny Tariffmodell (2026))

Voltage regulation and flexibility

From 2028 the voltage-regulation component charges all customers per MW of mean active power (because active-power flows drive the need) and lets customers volunteer for remuneration per Mvar when their reactive-power exchange regulates voltage. Svk buys dynamic voltage resources such as STATCOM units; customers’ own contribution, mostly from directly connected production, already covers much of the need. Remuneration is weighted 0.85 against Svk’s own equipment, needs at least 15% of settlement periods classed as voltage-regulating in a month, and conditions on a connection agreement covering voltage and reactive power; Svk expects customers’ contribution to grow by up to 20% and estimates an added cost of about 440 MSEK, about 5% of the tariff before reduction. The component is the only one that adds cost for the customer group as a whole.

A storage category in the fixed fee is planned for 2028 because several respondents wanted storage not to pay both injection and withdrawal fees (see Energy Storage). Temporary weekly subscriptions stay available when there is free capacity. A lower bound on annual subscriptions could free about 3,000 MW of capacity if customers also lower their connection-agreement power; sum subscriptions (power moved between nearby points of one customer in one price area) remain, but all existing ones end on 31 December 2026 and must be reapplied for.
