MISO and its Monitor are making several changes to market mitigation procedures — most of which will increase the IMM’s authority to mitigate and penalize.

FERC proposed to exempt market participants in ISO-NE, MISO, NYISO and PJM from its indicative horizontal market power screens.

Powerex is navigating a turbulent relationship with EIM rules the company says undercut the value of its hydro power resources.

Bidders in the ISO-NE capacity auctions would face a lower price threshold for triggering market power reviews under a Tariff revision filed by the RTO.

MISO won FERC permission to expand its mitigation measures on narrowly constrained areas to address intense but temporary congestion.

FERC denied requests for rehearing of its order that approved capacity market changes to prevent ISO-NE generation owners from economic resource retirement.

California’s scorching heat pushed CAISO day-ahead energy prices to record highs in the second quarter after market mitigation measures unexpectedly failed.

Berkshire Hathaway Energy subsidiaries PacifiCorp and NV Energy asked FERC to lift bidding restrictions placed on them in the EIM.

FERC approved MISO’s more stringent capacity withholding rule while also allowing the RTO to remove demand response from market monitoring.

MISO proposed creating a new category of narrowly constrained areas (NCAs) identified by momentary congestion and associated market power.
