MISO revealed it will crack down on demand response testing requirements ahead of its spring capacity auction, while some stakeholders argued the stepped-up measures amount to a change that requires FERC approval.

MISO will waste no time in 2025 trying to blunt the threat of a shortage that could arrive in the summer months by encouraging new generation and enacting further resource adequacy measures.

FERC ordered Ketchup Caddy and its owner to pay $27 million in penalties for dishonestly offering demand response services in MISO’s capacity market from 2019 to 2021.

FERC was not persuaded by environmental nonprofits, utilities nor Mississippi regulators to order MISO to rework the sloped demand curve it’s been cleared to use in the spring capacity auction.

Load-serving entities that decide against participating in MISO’s capacity auction must secure anywhere from 1.5% to 4.2% beyond their reserve margin requirements in the 2025/26 planning year.

Nearly a decade on, the saga over Dynegy’s manipulation of MISO’s capacity market continues, with FERC denying the company’s asks for procedural changes that might have softened repercussions in the case.

MISO said it will likely split load-modifying resource participation into two options in an effort to line up their true contributions with accreditation.

Ameren executives have reassured shareholders that Missouri’s capacity shortfall beginning this summer is no cause for panic.

MISO juggled several projects over 2023 designed to fend off imminent reliability problems and will keep up the multitasking in 2024.
