MISO maintained reliable operations in its South region during a record January cold snap that saw the area’s peak loads approach summertime highs.

MISO officials said a temperature forecast short by just 3 degrees Fahrenheit triggered a maximum generation event Sept. 22.

MISO said it expects to have plenty of reserve capacity to cover upcoming winter operations, even as it announced a review of an emergency declaration.

Most load-modifying resources called up during the MISO April 4 maximum generation event failed to respond properly to scheduling instructions.

MISO last month called on load-modifying resources for the first time in 10 years after it declared an unusual mid-spring maximum generation emergency.

At the MISO Informational Forum, stakeholders were briefed by a special agent from the FBI about cybersecurity threats against the grid.

The PJM MRC heard first read Thursday on proposed rule changes to day-ahead resource commitment and scheduling reserve requirements.

Acknowledging they were taking “a leap of faith,” stakeholders last week endorsed PJM’s plan for cutting uplift and capturing reserve costs in energy prices.

Stakeholders split last week over a PJM proposal to change how the RTO captures the cost of deploying additional reserves during extreme weather.
