MISO said 2025 was the most demanding summer since 2012, though it steered the grid with only a single maximum generation event.

The MISO Independent Market Monitor called on the RTO to develop a penalty system for generation for underperformance during emergencies.

MISO Midwest entered emergency status during the RTO’s first serious heat wave of the summer.

PJM credited emergency procedures with improving generator performance during a pair of winter storms in January, including a new all-time winter peak of 145,060 MW.

MISO and the Tennessee Valley Authority hope to implement an emergency energy purchase framework by Christmas Eve.

MISO and the Tennessee Valley Authority are poised to strike an agreement on emergency energy transactions after months of RTO leadership complaining that TVA doesn’t return the favor of energy transfers in times of need.

MISO expounded on why its late August maximum generation emergency wasn’t met with prices dictated by its emergency offer floors.

MISO's August demand rose compared to a year ago, while prices dropped by nearly two-thirds.

MISO officials said they probably could have held off their decision to call a summertime emergency in late August.

MISO said it can likely take on fall with sufficient capacity and minimal operating challenges.
