PJM faced several high load forecasts and hot weather alerts last month but never had to take emergency procedures, the Operating Committee learned.

PJM experienced 77 emergency procedures in May, staff told attendees at last week’s Operating Committee meeting.

PJM ordered its first load-shed event since implementing Capacity Performance in 2015 after a transmission line in Indiana tripped offline.

MISO Chairman Michael Curran last week denied an RTO Insider story quoting him as saying that the RTO should “burn down” the 3,000-MW limit on flows between its North and South regions if necessary to prevent load shedding.

The PUCT asked staff to revise a rulemaking on emergency response service, saying it didn't favor expanding the program to avoid local blackouts.

The Michigan PSC wants FERC to force MISO to turn over a study used to identify areas that require the operation of system support resources (SSR) in the state’s Upper Peninsula.

FERC last week approved a new reliability standard that will allow PJM and other transmission planners to plan for “non-consequential” load loss following a single contingency.

PJM cut loads in IN, MI, OH and PA Tuesday as a 90-degree heat wave pushed loads to the highest ever for September, stressing the grid at a time when much generation and transmission was offline.
