Sweden's Cable Pause Leaves Danish Power Prices at Double Swedish Levels
Stockholm's decision to suspend a planned 1 GW cross-border link has widened Nordic price spreads, with Danish day-ahead power sitting nearly twice Sweden's equivalent on Monday.
Day-ahead electricity in Denmark's DK1 zone settled at €150.27 per megawatt-hour on Monday (2026-06-23), against €78.82 in Sweden's SE3 zone — a gap that directly reflects the consequence of Stockholm's decision to suspend planning for a new 1 GW power cable between the two countries. Sweden halted the project on Friday (2026-05-15), citing a dispute over proposed EU grid rules, and Danish industry groups have since argued the move is costing consumers and distorting regional markets.2
The Danish Energy Association called Stockholm's pause the "wrong direction" on Wednesday (2026-05-21), arguing that more interconnection capacity, not less, is what the region needs as variable renewable output climbs. Prices in the DK2 zone, covering eastern Denmark, settled at €149.43 on Monday (2026-06-23), while Sweden's SE4 zone — which borders DK2 — cleared at €123.45. The persistent spread across the Øresund suggests existing links are running close to capacity during peak demand hours, and that the absence of new cable construction is already measurable in traded prices.2
Sweden's position stems from dissatisfaction with the European Commission's revised network code proposals, which would impose new obligations on how cross-border capacity is allocated and priced. Stockholm has not said when planning would resume, leaving the timeline for any new interconnector uncertain. That ambiguity sits uncomfortably with Denmark's own decarbonisation targets and with a separate offshore energy island project designed to link Danish offshore wind with continental markets.4
The Danish energy island — a proposed hub in the North Sea designed to connect Denmark and Germany — faces its own cost and security challenges, with high construction estimates and rising concerns about infrastructure vulnerability in the Baltic region. A delay in the Sweden–Denmark cable does not directly affect the offshore island, but it reinforces a broader pattern of Nordic hesitation about new cross-border wiring at a time when Europe is trying to build a more unified grid.4
Kristian Ruby, head of Eurelectric, weighed in on Thursday (2026-05-21), describing the reluctance of Norway and Sweden to build new power interconnectors as a "problem." His position reflects the wider view among European utilities that market integration reduces system costs and helps absorb renewable variability across geographies.1 Both Norway and Sweden have significant hydro reserves that could, in theory, buffer wind intermittency in Denmark and Germany — but only if cable capacity exists to move that power.1
A report from Thema Consulting, released on Tuesday (2026-04-28), offered a partial substitute argument: Germany's planned 12 GW of new gas-fired capacity, to be supported by a capacity mechanism, could dampen price spikes in the Nordic market by tightening the link between continental and Scandinavian price formation.3 That effect would work mainly through existing interconnectors between Germany and Denmark, and between Denmark and the wider Nordic pool. More cables would amplify it; fewer would constrain it.
The EU rules dispute at the heart of Sweden's pause is not a bilateral quarrel with Copenhagen. Several member states have objected to aspects of the Commission's grid proposals, and Swedish officials have indicated that their concerns relate specifically to market design principles affecting how network costs are socialised. Whether those objections can be resolved in upcoming technical negotiations will determine whether the paused cable eventually moves back into active planning or remains in limbo.2
Denmark and Sweden are among seven EU countries that in early June (2026-06-08) signed a joint paper opposing any further dilution of emission reduction targets for automakers. That alignment on climate ambition makes the cable dispute more pointed: both governments want faster decarbonisation of power and transport, but are struggling to agree on the infrastructure rules that would make a shared clean energy market viable.5
For traders watching Nordic power, the DK1–SE3 spread is the clearest live signal of where the policy impasse is landing. The spread has been volatile through May and June, amplified by Denmark's heavy reliance on wind — which produces more power than the country can use in windy periods but leaves it exposed when the wind drops and import capacity is constrained. Sweden's decision on when to restart the cable planning process, and whether the EU network code revisions produce a framework Stockholm can accept, will determine whether that spread narrows or stays wide through the second half of the year.2,1
