UN warns: AI data centers connect faster than networks are built

The United Nations Economic Commission for Europe estimates the time lag: two to five years to build a data center, more than ten years to extend the transmission lines that will supply it.

In a report relayed on 8 September 2026 by the United Nations, the Economic Commission for Europe (UNECE) points to a schedule gap that has become structural: a large data centre can be built and connected in two to five years, while the extension of the necessary transmission lines and network infrastructure often takes more than ten years, including regulatory procedures.

Orders of magnitude explain the tension. Data center electricity consumption would increase from 485 TWh in 2025 to 950 TWh in 2030, nearly double and about 3% of global demand, while investment in grids would only double by 2050, to $1,800 billion per year. The effects are already being seen where grids rely heavily on renewables: voltage fluctuations, unforeseen disconnections, and the risk of cascading failures when AI-related demand changes sharply.

UNECE identifies three regulatory blind spots: the lack of a clear rule on who finances network reinforcements, the lack of supervision of installations — installations are concentrated in the same favorable areas and saturate local capacity — and the lack of real-time consumption data accessible to regulators. Ireland and the Netherlands have already introduced restrictions to contain the pressure on their networks.
