ON.energy Demonstrates Zero-Voltage Ride-Through for AI Data Centers in Independent Testing
MIAMI--(BUSINESS WIRE)--Following ON.energy’s January 2026 deployment of AI UPS™ at the U.S. Department of Energy’s National Laboratory of the Rockies (NLR), the company today released independent validation results demonstrating the medium-voltage system’s performance under real-world conditions, with results benchmarked against ERCOT's proposed large electronic load (LEL) ride-through requirements. The testing, conducted at 13.2 kV using NLR’s distinct 7 MW and 20 MW controllable grid interface (programmable power supplies) acting as grid and load simulators respectively with GPS-synchronized data acquisition, covered all voltage ride-through requirements while maintaining AI workload transients. The results come as NERC issues a level 3 alert and ERCOT advances NOGRR 282, a proposed revision that establishes frequency and voltage ride-through requirements for Large Electronic Loads, such as AI data centers and hyperscale compute facilities. ERCOT’s Reliability and Operations Subcommittee (ROS) approved the measure on April 2, 2026, ahead of potential Board endorsement in June and PUCT ratification by July. Under ERCOT’s current interim energization framework for large loads, demonstration of ride-through capability is already a condition for interconnection approval.
