Lessons from the Jan. 17 MISO South emergency resulted in smoother management of the Sept. 15 emergency in the region, RTO officials told stakeholders.

NYISO experienced six days with peak loads of more than 31,000 MW this summer, compared with last summer’s actual peak of 29,677 MW.

A systemwide emergency, market innovations and the relatively calm summer topped the discussions at MISO’s Board of Directors meetings.

MISO declared a maximum generation alert Sept. 17 because of tight reserve levels amid forced outages and hotter-than-expected temperatures.

MISO has sufficient resources available to cope with warm conditions this fall, although there is a risk it may be forced to order emergency procedures.

Hot and humid weather and several unplanned generator outages sent ISO-NE power prices soaring Monday and led the RTO to purchase emergency energy.

MISO issued two maximum generation alerts and conservative operations declarations because of severe weather in June and a heatwave in July.

NYISO experienced a peak load of 31,293 MW on July 2, the highest demand so far this summer but falling far short of the all-time peak of 33,956 MW.

A high-pressure system that has swamped much of Texas with triple-digit temperatures has led to all-time systemwide peak records in ERCOT.

ERCOT set new all-time systemwide peak demand records July 18, reaching 72.2 GW between 4 and 5 p.m.
