Finland must act now to avoid future electricity shortfalls
Experts warn that rising demand from data centres and district heating could outstrip Finland's domestic power capacity, risking supply gaps unless new flexible generation or demand-side measures are introduced.
On a typical cold winter day Finland can produce roughly 12 GW of home-grown electricity and has a nominal wind capacity of about 10 GW, while imports from Sweden and Estonia total just over 4 GW. With annual consumption around 85 TWh and peak demand hitting 15 GW, a calm wind spell could leave a 3 GW gap that is usually covered by imports. The authors note that growing demand from data-centre construction and the shift to electric district heating will increase the risk of such gaps.
They contend that market incentives favour wind and solar, leaving little motivation for capacity that can be ramped up or down on demand. To safeguard the grid, they propose new flexible generation, demand-reduction tools, larger heat-storage facilities, and possibly mandatory backup generators for large data-centre operators. Strengthening the system’s resilience, they say, also requires a distributed network of reserve power plants across the country.
Why it matters
A power shortage would affect households, industry and Finland's climate goals, making early planning essential.
