Powering AI is an architecture problem

MIT Technology Review · 1 month ago · 4

Transmission-line faults and surge arrester failures in Ashburn, Virginia caused more than 3 gigawatts and about 1,500 megawatts of AI data-center load to drop off the grid within seconds, showing the issue was grid architecture rather than power supply. The article cites an early-2026 full-scale test at the National Laboratory of the Rockies, where the system cleared ERCOT large-load voltage ride-through requirements with room to spare. By moving AI UPS and power conditioning from low-voltage, battery-based, bypass-heavy setups to medium-voltage, inline systems near substations, load swings become harder to notice and backup power can also support grid programs.
