Nordic Data Centre Demand Set to More Than Double by 2030, Norway the Biggest Driver
A new forecast projects regional consumption rising from 9 TWh in 2027 to 19 TWh in 2030, with Norway carrying the heaviest initial load.
Power consumption from Nordic data centres could more than double in three years. A long-term analysis published Wednesday (2026-07-29) by Montel Syspower projects regional consumption rising from 9 TWh in 2027 to 19 TWh in 2030 and reaching 28 TWh by 2035 — numbers that, if realised, would fundamentally reshape the region's generation and grid investment calculus.5
Norway is positioned to carry the heaviest early load. Montel Syspower forecasts Norwegian data centre consumption doubling from 4 TWh to 8 TWh between 2027 and 2030, the largest single-country increment in the study. That trajectory is already visible in grid operator data: Norwegian data centres used 2.8 TWh in 2025, a 70% rise from 2024. The pace, if it persists, will test both interconnector capacity and the country's hydropower scheduling well before 2030 arrives.5
Norway NO2 day-ahead power settled at €120.64/MWh on Wednesday (2026-07-29), giving data centre developers a live benchmark for cost exposure as they price multi-year offtake arrangements and weigh siting economics in a market where prices have run well above European averages.5
Finland adds its own weight to the regional picture. The Finnish Data Center Association told a Helsinki conference in May 2026 that operational capacity stood at around 368 MW, accounting for roughly 2% of national consumption; FDCA director Antti Poikola said demand is expected to more than triple to 1.2 GW by 2030, with further upside as additional projects advance.2
The grid connection queue is where near-term uncertainty concentrates. ENTSO-E warned in May 2026 that transmission system operators across Europe may be forced to reduce renewable energy penetration if data centre demand growth is not properly managed — a constraint that applies to Nordic markets despite their high renewable shares, given the gap between the pace of new data centre approvals and the speed of local grid buildout.4
Fortum chief executive Markus Rauramo offered a more measured view in an interview published Thursday (2026-05-21). Renewable capacity can in many cases meet growing Nordic data centre demand without new nuclear investment in the short term, he told Montel. Whether that holds as consumption approaches the Montel Syspower upper-end projections depends heavily on how quickly interconnection and grid expansion keeps pace with the incoming load curve.1
There is an operational lever that could change the arithmetic substantially. A study published Monday (2026-04-20), cited by Montel, found that flexibility in data centre operations could cut their contribution to peak power demand by up to 45% in 2035, avoiding the need for 4 GW of fossil fuel back-up capacity across the broader European grid. Applied to the Nordic context, that implies the demand peaks embedded in the Montel Syspower projections could be significantly smoothed — but only if operators, TSOs and market regulators align on mechanisms to incentivise load shifting.3
The Montel Syspower study carries an explicit confidence score of 0.60 on its headline numbers, reflecting genuine uncertainty over the pace of AI infrastructure deployment and which sites secure grid capacity first. A slowdown in hyperscaler spending or tighter local permitting could see the 2030 figure undershoot; several large projects currently advancing are not yet reflected in the 9 TWh 2027 baseline, leaving the upside scenarios plausible without any delivery guarantee.5
Norwegian TSO data for 2026 will be the near-term check. Data centres drew 2.8 TWh across all of 2025; if the annualised 2026 figure runs above 4 TWh, the Montel Syspower 2027 baseline starts to look conservative from the outset. Grid application queues in Norway and Finland provide the clearest early read on whether the study's central scenario is tracking or already understating the pace of incoming load.5,2
