$953/MWh at MISO Michigan Hub is a clean stress signal, not noise. The move was about 20x the 24-hour mean, which is the kind of ratio that usually comes from a local supply-demand mismatch, not broad system drift.

MISO’s outage tape was busy around the same window: 60 generation-outage events over the last 7 days, with forced-outage snapshots showing 6,566 MW, 12,639 MW, 2,319 MW, 3,754 MW and 7,041 MW at 2026-04-16 05:00. That is enough rotating and forced derate pressure to keep the dispatch stack brittle, especially if the problem clusters near Michigan or along export-constrained paths feeding the hub. The market also has a structural reason to stay twitchy: MISO expects load to jump 35% by 2035 on data center growth, which makes today’s tight hours easier to reproduce when outages and load stack on top of each other.

The key question for today is not whether the hub can print high again, but whether the same constraint set is still in place. If the next RT hour holds elevated compared with the 24-hour mean, then the recurrence case is intact; if prices mean-revert while outages persist, that points to a transient local issue rather than a broader scarcity regime. Watch any divergence between Michigan Hub and the wider MISO footprint: if the hub stays rich while system prices cool, the spread is telling you the bottleneck is local, not systemwide.

> $953/MWh says Michigan did not need a system emergency to clear like one.
