About the Kapacitetskarta

Svk’s Kapacitetskarta transmissionsnätet is a public tool launched in May 2026 providing an indicative, county-level view of available capacity on the Swedish transmission grid (stamnätet). The stated purpose is to give market actors an overview of grid headroom before committing to formal connection applications, and to enable dialogue between Svk, county authorities, DSOs, and large consumers. Monthly updates begin June 2026.

The map is a first version: county granularity only (based on substation geography, not grid topology); time dimension limited to 2026 with a 2027–2035 forward view. Svk has stated it will add 2030 and 2035 horizon years later in 2026. This map is the precursor to the formal kapacitetskarta envisaged as part of the Anvisningssystem proposal (April 2026), which would show capacity at kapacitetszoner (connection-point level) at 5- and 10-year horizons.

Scope limitation: the map covers transmission grid only. Most Swedish connections are to regional and local distribution networks, not the transmission grid directly. The map gives no visibility into DSO-level capacity constraints.

Column definitions

All values in MW. The 2026 indicative column and the 2027–2035 columns use different network models (the future model includes planned reinforcements not yet built). Svk explicitly states they cannot be added to or subtracted from each other to calculate a total available capacity. County figures also cannot be summed to a national or regional total.

Methodology caveats

• County = substation geography: each county’s figure is based on substations physically located within that county. Because the grid does not follow county borders, a station in one county may serve adjacent counties. A low figure in a county does not mean that county is “closed” — adjacent stations may provide alternative paths.
• 500 MW display ceiling: the map uses five color bands (< 50, 50–150, 150–300, 300–500, > 500 MW). Values of exactly 500 in the raw data represent the “>500 MW” band — actual capacity may be substantially higher.
• Ansökt not included in 2026 model: applications that have not yet received a förhandsbesked are excluded from the near-term capacity calculation, so a county can simultaneously show substantial available 2026 capacity and a very large ansökt queue.
• Projects in pre-application stages excluded: further filtering at the ansökt level means the queue figures likely understate total speculative interest.

Dataset (snapshot 2026-03-02, all values in MW)

“500+” = raw value was exactly 500, representing the “>500 MW” display band ceiling. ”—” = null (Gotland: island grid, separate constraints).

Key findings

Consumption (uttag) — two Sweden

The data reveals a stark north-south split for new consumption connections:

• Constrained south: Stockholms (0 MW), Uppsala (0 MW), Södermanlands (0 MW), Kalmar (0 MW), Västra Götalands (0 MW), Värmlands (0 MW), Gävleborgs (0 MW) all show zero near-term uttag capacity. Stockholm is fully saturated even for 2026; this drives the SEK 30 billion Stockholm reinforcement package. Sörmland and Kalmar also have large reserverad queues indicating near-term absorption of capacity.
• Headroom north: all northern counties (Dalarnas, Västernorrland, Jämtland, Västerbotten, Norrbotten) show 500+ MW available for new consumption — consistent with SE1 being structurally surplus and able to absorb new industrial load without requiring south-to-north flows.

The Norrbottens connection queue

Norrbottens shows 22,750 MW ansökt uttag — by far the largest value in the dataset, roughly 3× Sweden’s national peak load and ~6× Sweden’s current total installed production capacity in the north. This reflects the pipeline of industrial electrification applications: green steel (LKAB, SSAB H2 Green Steel), electrolytic hydrogen, data centers, and battery factories concentrated in SE1. Even heavily discounted for speculative applications, the realized fraction of this queue would be transformative for northern grid infrastructure needs.

Norrbottens also has the largest tilldelad uttag (2,810 MW) — confirming that a substantial fraction of this demand is already through the connection process and committed for 2027–2035.

Production (inmatning) — southern surplus

Most southern counties show 500+ MW of available inmatning capacity with little pending consumption to balance it. This confirms the structural pattern documented in Bidding Areas: SE3/SE4 are net consumption zones where further wind/solar can technically connect but the north-south transmission bottleneck limits export. Hallands (1,130 MW tilldelad + 2,500 MW ansökt inmatning) and Västra Götalands (3,600 MW ansökt inmatning) show the largest southern production pipelines, consistent with offshore wind development interest along the west coast.

Värmland anomaly

Värmlands shows 0 for both uttag and inmatning in 2026 with only 1 MW reserverad uttag — unusual for a county with significant industrial and hydropower presence. The likely explanation is that Värmland’s transmission substations are geographically placed to serve adjacent counties (Dalarna, Örebro, Västra Götalands), so the county’s effective capacity does not register in this county-based methodology. The large ansökt figures (1,400 MW uttag, 2,800 MW inmatning) suggest long-term interest despite apparent near-term saturation.
