Report: Power supply issues slow EMEA data center rollout

A Savills report found that data centre capacity growth in Europe, the Middle East, and Africa has slowed since 2025 compared to last year's same period, despite a surge in demand. This is due to a lack available power, which delays project timelines.

Since ChatGPT's release in late 2022 the global data centre demand has risen and projects are being planned. Investors and governments have bet that generative artificial intelligent will revolutionise how we all work and live. The demand for electricity to power these centres has increased.

Savills, a global provider of real estate services, reported that since January, new data centres have added 850 megawatts of power, which is 11% less than the same period in 2024.

Megawatts are the main metric for sizing a data centre. This is the maximum power that a data center can provide to its servers, cooling systems and other infrastructure.

Savills reported that overall data centre capacity has increased by 12% to 11,400 MW, from 10,140MW a year ago. The report stated that the decline in power delivered year-to date is largely due to persistent energy supply constraints which have delayed projects, and not because of a decrease in demand for data centers.

Savills stated that the demand for these centres continues to surge, resulting in an imbalance and a restricted supply of power.

The actual amount of new capacity that was occupied fell to just 845 megawatts. This is only half the power capacity leased by 2024. The figures include also pre-lets, which are leases for future data centers.

The total contracted power capacity, which includes both the live and future contracted capacity, grew by 12% on an annual basis to 14,500MW. This shows a strong under-demand.

In the third quarter 2025, 91% all data center capacity was leased. This is up from 87% during the same quarter in 2022. This also reflects a strong demand. (Reporting and editing by Amanda Cooper, Emelia Sithole Matarise and Lucy Raitano)
