European Data Center Power Deals Drop 38% Amid Offshore Wind Delays

The European market for clean power deals supporting data center expansion has contracted sharply. Power purchase agreement (PPA) volumes dropped from 4.2 gigawatts (GW) in 2024 to 2.6 GW in 2025, a decrease of over 38%. This downturn is occurring even as the physical buildout of data center capacity in Europe is accelerating. Several factors are contributing to this disconnect, primarily stemming from delays in offshore wind projects, a key source of clean energy for these facilities. Furthermore, the negotiation of PPA price points has become increasingly difficult. This is driven by several market dynamics: falling capture rates, which reduce the effective price generators receive for their power, and a rising frequency of negative wholesale power prices. Negative pricing is particularly prevalent for solar photovoltaic (PV) generation, where supply can exceed demand during peak production hours. The intensified competition to secure reliable and clean power is prompting some major hyperscale cloud providers to re-evaluate their previously ambitious clean energy procurement strategies. This moderation in demand signals could impact the financial viability and development timelines of new renewable energy projects, particularly those reliant on long-term PPA commitments from large industrial consumers. Investors and operators in the renewable energy sector, especially offshore wind developers, may face increased financing challenges and pressure to secure alternative offtake agreements. Data center developers, meanwhile, could experience higher energy costs or delays in project commissioning if clean power supply cannot keep pace with demand. The situation warrants close monitoring as it could reshape investment flows and development strategies across both the data center and renewable energy industries in Europe over the coming weeks.
