AI datacentres pose growing threat to electricity systems worldwide (news.un.org)

AI datacentres are emerging as a substantial challenge to global electricity systems, according to a warning from the UN's Economic Commission for Europe (UNECE). The demand from these energy-intensive facilities is projected to nearly double by 2030, potentially consuming 950 Terawatt-hours (TWh) annually, which could represent 3% of global energy demand. However, investment in necessary electricity infrastructure is expected to lag, increasing only from $800 billion in 2026 to $1.8 trillion by 2050. This disparity raises concerns over the reliability of energy systems, particularly as power grids struggle to keep pace with the rapid construction of datacentres. The UNECE highlights the risks posed by overloading electricity systems, which could lead to voltage instability and cascading failures, particularly in regions reliant on renewable energy sources that cannot adjust to sudden spikes in demand. Coupled with unresolved questions about cost-sharing for grid upgrades and insufficient regulatory frameworks governing datacentre placement, the situation calls for urgent regulatory reforms. These reforms should aim for better coordination and comprehensive regulations to ensure energy systems can adapt to the burgeoning energy requirements of AI technologies while maintaining resilience against potential disruptions.
