Sweden's north-south grid divide could cap value of new wind and solar capacity, GlobalData says

GlobalData expects Sweden's installed power capacity to grow at a 2.9% CAGR from 2025 to 2035, with wind and solar driving the expansion. Hydro and nuclear remain the firm low-carbon base. The catch is geography: most new renewable generation sits in the north, while demand from industry, data centers, and population centers is concentrated in the south. Limited north-to-south transmission capacity means northern clean power could be curtailed or exported while southern buyers face higher prices and volatility. GlobalData says Svenska kraftnat's transmission upgrades are as important as new generation, and that permitting, offshore wind delivery, and financing for nuclear will decide whether Sweden can turn its resource advantage into reliable, affordable power.

The interesting part is the CAGR number. 2.9% for a decade sounds modest, but Sweden already runs on hydro and nuclear, so the growth is mostly about wind and solar on top. The real question is whether the grid gets built before the projects do.

Would like to see more detail on Svenska kraftnat's actual timeline. Saying transmission upgrades are critical is true, but Sweden has been talking about north south bottlenecks for years. What matters is which lines get permitted, and when construction actually starts. Curtailment numbers will tell the real story.

The electricity certificate wind down changes things more than the article lets on. New renewables will need to stand on merchant or corporate PPA revenue, and that makes grid connection timing even more important. A project waiting in the queue is not earning anything.

Worth noting that southern consumers already pay higher prices because of the zone split. If industrial electrification lands in the south before transmission catches up, the price gap could get worse. That may slow down the fossil free steel and battery projects people are counting on.

Offshore wind is the long shot here. The article lists permitting, defense approvals, seabed access, all of that. In practice those processes have killed projects in other markets. Onshore wind and solar with existing connection capacity may deliver more in the next five years.

Nobody is talking about demand side response in the south. If transmission is the bottleneck, flexible loads and storage at the consumption end can reduce the pain while lines get built. Cheaper than a new interconnector, but it needs a market design that pays for flexibility.
