The United Nations Economic Commission for Europe (UNECE) warned that AI data center buildout is outpacing electricity grid expansion worldwide, according to a press release covered by UN News. Global AI data center electricity consumption is projected to nearly double, from 485 TWh in 2025 to 950 TWh by 2030.
UNECE noted that a data center can be built in two to five years, while new transmission infrastructure typically takes ten years or more to plan and construct — a mismatch that raises the risk of voltage oscillations and cascading grid failures, particularly on renewables-heavy grids that are less able to absorb sudden AI-driven demand spikes.
Why it matters: The warning adds an authoritative, non-industry voice to a debate that has so far been driven mostly by hyperscalers’ own announcements of multi-gigawatt buildouts and power-purchase agreements; it frames AI infrastructure growth as a grid-stability and critical-infrastructure planning issue, not just a capacity or investment story.
