Fortum's Swedish Nuclear Aid Bid Meets a Nordic Market Already Braced for Lower Prices
Fortum has asked Stockholm to share the cost of new reactors ranging from 1,200 MW to 3,400 MW, just as analysts see Nordic spot power sliding on rising nuclear output.6,4
Fortum confirmed on Thursday (2026-08-27) that it had filed a state aid application with the Swedish government, opening talks on terms to advance a new nuclear project in Sweden. The company has not committed to a site, a reactor count, or a final capacity figure. The scope under discussion ranges from 1,200 MW to 3,400 MW, and Fortum says the final number depends on technology selection, the benefits of building multiple units, and expected growth in Swedish electricity demand.6
Stockholm has already rewritten its 2040 target from "100% renewable" to "100% fossil-free," a change that exists to let nuclear count toward the goal. Fortum's application asks the state to put money behind that wording.6
Yet the near-term Nordic price curve is moving the other way. Analysts told Montel that Nordic spot power is expected to slide 26% quarter on quarter in the third quarter of 2026 to average around EUR 50/MWh, down from EUR 68/MWh in the second quarter, citing easing demand and rising nuclear output.4
New reactors take the better part of a decade to build. The market is clearing at half the level that financial close on a 3,400 MW project would require, which is precisely why Fortum is asking the state to underwrite part of the bill now rather than waiting for a signal from Nord Pool.6,4
Hydro is not providing the usual support either. Nordic hydropower reserves sit 26 TWh below normal, with a 14-day outlook that remains drier than normal, according to Montel EQ. That deficit has historically been the bull case for Nordic power prices. It is not behaving like one.2
The counterweight, analysts argue, is European renewables. A sharp increase in renewable output across the continent should pull more power across the interconnectors and limit the impact of the Nordic hydro shortfall, analysts told Montel. That is a forecast about flows, not a settled outcome, and it depends on weather conditions the continent has not yet produced.2
Fortum is not alone in anticipating higher demand. Bitzero signed a binding letter of intent with OneQode Networks on May 5 (2026-05-05) covering the full 110 MW capacity of its Namsskogan, Norway data centre site under a 15-year lease tied to GPU-based AI workloads. The deal carries an implied value of roughly $2.6 billion over the lease term. Bitzero also controls additional Norwegian expansion capacity tied to a development pipeline management says could scale well beyond 300 MW as grid upgrades continue.3
Those are exactly the long-duration, high-load-factor customers that make a merchant nuclear case easier to structure. But the lease covers 110 MW. Fortum is considering up to 3,400 MW. The gap between contracted demand in the Nordics and the supply being proposed is bridged by a projection, and projections shift when power prices fall.3,6
The wider gas complex is not offering scarcity pricing to reinforce the investment case. ICE Endex TTF front-month settled at EUR 79.51/MWh at Friday's (2026-09-11) close, down 3.31% on the session, and THE front-month settled at EUR 80.55/MWh, down 3.27% on the same session. Gas prices set the floor beneath which coal-to-gas switching reverses in European generation; at these levels, neither European carbon demand nor Nordic power import economics are being driven by scarcity.2
Analysts have already flagged the systemic shift underlying these prices. The growth of green generation has made European and Nordic power systems more resilient to a gas supply shortage than during the 2022 crisis that followed Russia's invasion of Ukraine, they told Montel. More resilient systems mean fewer price spikes, and fewer spikes mean thinner revenue for any generator asking to be paid for reliability.1
That context shapes what Fortum's application actually signals to the market. If Stockholm agrees to a support mechanism before the project's capacity is firmed, it tells other developers in the region that the state will carry merchant risk in exchange for firm, fossil-free megawatts. If it does not, the 1,200 MW low case becomes the likely outcome and the Nordic supply story stays a forecast rather than a build.6
Nord Pool is pressing its own expansion regardless. The exchange plans to extend its financial power futures offering into European countries in 2027, adding to its Nordic and Baltic presence, its chief executive told Montel. More liquidity does not change the physics of a hydro deficit or the timeline of a reactor. It does change who gets to hedge them.5
