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.

The bulk power system showed improved ability to rebound from severe storms last year while continuing to improve on most other reliability metrics.

Electric reliability in New York state declined last year compared to 2016 because of a severe wind storm in March, staff told the NYPSC.
