Stiffer penalties for MISO demand response raise reliability and exit risk

FERC backed MISO's harsher penalties for demand-side resources that fail in emergencies, a move that could cut fraud but also thin out flexible capacity.

On Oct. 23, 2026, FERC largely approved MISO's plan to penalize demand-side resources that fail to perform during grid emergencies. The framework is scheduled to take effect June 1. It covers Load Modifying Resources: demand response and behind-the-meter generation that receive capacity payments in exchange for agreeing to respond when MISO calls on them.

The rules expand existing participation restrictions, distinguish partial from complete performance failures, and add a financial penalty tied to auction clearing prices. MISO says this finishes a series of FERC-approved changes made after several enforcement cases. Those include a Voltus settlement ($10.9 million penalty plus $7.1 million in returned profits), roughly $22 million from Big River Steel, $66.7 million from Northern Indiana Public Service Co. and Linde, and about $27 million ordered against Ketchup Caddy and its owner for fake demand response resources. Citing MISO, FERC said old penalties barely deterred fraud, since LMRs are called rarely compared with the payments they collect.

The scale matters. In MISO's latest summer auction, demand-backed LMRs cleared 9.1 GW and behind-the-meter generation cleared 4.3 GW, together 9.4% of planning resources. Flexible load is among the cheapest ways to cover peak stress, so credibility matters, and so does keeping it plentiful. Real reliability makes the capacity worth paying for. Penalties that are too steep could make honest participants leave.

That second risk is the one to watch. Commissioners Judy Chang and David Rosner urged monitoring, warning that excessive penalties could drive resources out and raise adequacy costs. That is a warning, not an observed outcome. Advanced Energy United and two public power groups called the penalties too extreme, and FERC rejected that. MISO has 30 days to fix an inconsistency in how two LMR penalty types are calculated. One analyst also noted that aggregators lack firm timelines for node designations from utilities, a barrier outside this order. The source article is a brief and appears truncated.
