Twitter users were quick to pounce on ERCOT's quiet release of its winter resource assessment and the resignation of a new board member.

NYISO on Tuesday reported sufficient capacity this winter to meet forecasted peak demand conditions, with a total of 42,415 MW of resources available.

PJM wants to modify the generator deliverability tests for light-load and winter periods as more renewable energy is set to come online.

MISO concluded that its current suite of resource adequacy tools, and the in-progress projects it is working on, enable it to cope with extreme cold snaps.

SPP COO Lanny Nickell pointed to a lack of gas generation as the culprit behind the first load sheds in the grid operator’s history.

Within two decades, increasing load from electrification will have MISO operating on a winter peaking model, RTO staff said.

February's cold snap set MISO’s winter peak this year but didn’t unseat the grid operator’s all-time winter demand record, stakeholders learned.

NYISO officials briefed the Management Committee on the ISO's performance during an historic snowstorm in December last year.

MISO staff and stakeholders clashed in front of board members on whether the RTO’s proposed capacity accreditation design should move forward.

MISO reiterated the extraordinary nature of mid-February’s winter storm, promising more data later this month and resource adequacy solutions by year-end.
