Data Centers are recognized as the largest provider of new electricity capacity in Finland. This shift in contracts towards sources that guarantee sustainable energy supply is clearly evident. For example, Google’s 507-megawatt contract with Fortum in Loviisa has been registered as the first nuclear power purchase agreement in Finland. This 22-year agreement maintains 10 percent of the country's electricity that was set to be phased out by 2030.
Sustainable Energy Supply Trends
Rystad Energy predicts that the next wave of energy supply in Finland will continue in this manner, providing a mix of wind and solar energy with battery energy storage systems (BESS). Finland is expected to be the fifth largest data center market in Europe by 2035, with installed capacity increasing from 0.8 gigawatts (GW) in 2026 to 5 gigawatts in 2035. By 2030, data centers are expected to account for about 15 percent of national electricity consumption.
Changes in Contracts and Network Access Challenges
Data centers are now the largest electricity buyers in Finland, and this gap is rapidly widening. The 507-megawatt Loviisa contract is the largest power purchase agreement in the country, surpassing Amazon's 367-megawatt contract with the Rajamenkyl wind project. This 22-year agreement is more than twice the length of wind and solar power purchase agreements in 2025 and 2026. Wind energy is expected to contribute to the expansion of renewable energy in Finland by 2035. However, the increasing share of wind and solar energy has led to negative electricity price hours, but battery capacity is rapidly expanding.
Access to the grid may become a bigger challenge. Finland has proposed replacing the "first come, first served" queue for grid connection with a prioritization method, which could impact data center and battery developers. This proposal rewards new developers who combine their loads with manageable capacities, especially in the heavily congested southern regions of Finland.
