MISO's Computational Loads Arrive With Rules Attached
Bruno Coelho··Critical Infrastructure
What happened. MISO filed a proposal at FERC on August 28 creating a computational-load class: large loads above 50 megawatts with at least 25 megawatts of IT-equipment demand. The obligations arrive in the same filing: ride-through performance during voltage and frequency events, ramp limits, phasor-measurement telemetry, and load forecasting, with a requested effective date of December 4 and further filings due by November 16.
Why it matters. This is the first reliability rulebook written for compute as a load class, and it sits inside FERC’s wider large-load push (the June show-cause orders, docket RM26-4). For AI engineering teams in utilities, the grid operator has started specifying how AI-scale compute must behave during grid disturbances.
What to do. Check which facilities would meet the 25 megawatt IT threshold and whether the platforms behind them ride through a voltage or frequency event without tripping. The window to shape the rules is short: motions to intervene run on a clock of roughly 21 days from the filing. The question to put to your CTO: which of our AI workloads sit behind connections MISO would class as computational loads, and can they ride through a disturbance without tripping?
Where I would be wrong. FERC could reject or modify the package, and other regions may not copy MISO’s thresholds, so engineering to these numbers now could mean rework. Waiting costs the intervention window, and the filing’s grandfathering terms mean timing decides which arrangements the new rules reach.
