Power supply constraints slowing EMEA data centre rollout, report says

Core Insights - Data centre capacity growth in Europe, the Middle East, and Africa has slowed in 2025 compared to the previous year, despite increasing demand due to power supply constraints [1][4] - Since the release of ChatGPT in late 2022, global data centre demand has surged, leading to a significant increase in planned projects and electricity capacity requirements [2] - Overall live data centre capacity has increased by 12% year-on-year, reaching 11,400 megawatts (MW) [4] Capacity and Demand - New data centre power capacity added since January 2025 is 850 MW, which is 11% lower than the same period in 2024 [2] - The decline in new power delivered is attributed to energy supply constraints rather than a decrease in demand for data centres [4] - Take-up of newly occupied capacity fell to 845 MW, which is only half of the power capacity leased in 2024 [5] Leasing and Contracts - Total contracted power capacity, including both live and future capacity, grew by 12% year-on-year to 14,500 MW, indicating strong underlying demand [5] - As of Q3 2025, 91% of all data centre capacity had been leased, an increase from 87% in the same quarter of 2022 [6]
