NYISO reported that it confronted minimal operating challenges this past winter as New York enjoyed relatively mild weather for most of the season.

MISO’s most recent maximum generation emergency is yet another portent of its increasing need to rethink grid operations, execs told the Board of Directors.

In the wake of its Jan. grid emergency, MISO pledged to further study generation cutoffs in extreme temperatures and improvements to its load forecasting.

MISO managed its eighth maximum generation event in six years last month despite the difficulty of pulling together the forecast leading up to the episode.

PJM survived last week’s arctic blast with slightly elevated outages and two periods of shortage pricing, officials said.

NYISO last month incorporated additional 115-kV transmission facilities in its energy market model, COO Rick Gonzales told the Management Committee.

A dangerous cold snap spurred a maximum generation event and knocked out power to MISO’s Carmel, Ind., offices on Wednesday.

MISO has issued a cold weather alert for several balancing authorities in its North and Central regions for Jan. 29 through Feb. 1.

ISO-NE said it expects to have sufficient capacity on hand this winter to meet load, which it forecasts will peak at 20,357 MW in normal conditions.

The Mid-Atlantic region experienced heavy precipitation this summer that was great for hydro generation, PJM staff told the Operating Committee.
