The European Power Gap: Data Center Expansion vs. Renewable Decline

The gap between surging data center capacity and declining renewable power purchase agreement (PPA) activity creates a structural deficit in Europe's energy strategy. While capacity buildout is accelerating, the mechanisms used to secure clean energy are faltering. Data center power purchase agreement volumes fell from 4.2 GW in 2024 to 2.6 GW in 2025, even as the demand for compute scales.

The expansion is massive. European data center capacity is forecast to grow from 16 GW in 2024 to 36 GW by 2030. The scale of this buildout is evident in the final stages of the decade, with about 12 GW added in the final two years alone—a figure that matches total European capacity as recently as 2022. This growth is driven by the demand for artificial intelligence (AI) compute, forcing hyperscalers and co-location operators to scale aggressively.

However, the energy supply side is decoupling from this demand. Annual PPA volumes have trended downward. Offshore wind, once the largest-volume segment, has seen signed volumes fall from 1.35 GW in 2024 to 0.5 GW in 2025. By the first quarter of 2026, these volumes reached just 100 MW, represented by a single Google offtake from EnBW's He Dreiht farm in Germany. Solar PV deals are also contracting due to falling capture rates and the rising frequency of negative wholesale power price hours.

This decline is not merely a matter of technology; it is a matter of economics and logistics. Offshore wind delays have removed the large-volume contracts that defined the 2024 peak. Simultaneously, a pricing disconnect is emerging. As hyperscalers face the necessity of securing power, some are reassessing their clean energy ambitions, which moderates the demand signals that previously supported European renewable PPA activity.

The geography of the expansion is also shifting. While the UK, Germany, France, and the Netherlands attract the largest new capacity volumes, growth is moving toward Ireland, Spain, Sweden, Norway, Italy, and Finland. Operators are moving beyond congested primary hubs where grid and permitting constraints extend timelines. The Nordic countries remain competitive due to low-carbon hydropower and lower ambient temperatures that reduce cooling costs.

Data center-related PPAs accounted for 20% of total European offtake between 2024 and the first quarter of 2026, making them the second-largest share behind manufacturing and industrial buyers.

The mismatch between a 36 GW capacity target by 2030 and the shrinking volume of renewable energy contracts suggests a looming energy crisis for the digital economy. If the industry cannot bridge the gap between capacity needs and PPA availability, the AI buildout will hit a hard ceiling.

The question for operators is no longer just about where to build, but how to power the load when the traditional renewable procurement model is breaking down.
