PJM plans to survey generation owners to determine what can be done to increase resource flexibility.

Below is a summary of 11 new recommendations resulting from PJM’s final report on the September 2013 heat wave. This is in addition to 11 recommendations made immediately after the events of Sept. 9-11.

The Planning Committee last week endorsed manual changes implementing PJM’s new capacity import limits.

Sub-zero temperatures from Toledo to Tennessee pushed PJM to its limits last week as the RTO overcame the loss of nearly 40,000 MW of generation during an arctic blast that set a new winter demand record.

PJM is adding more items to the to-do list resulting from the September heat wave, during which officials ordered limited load sheds to prevent a wider transmission collapse.

PJM operators dispatched demand response this morning after cutting voltages and calling on spinning reserves last night as frigid temperatures stressed generators and created record loads across the RTO.

MISO began running the nation’s biggest RTO by geography with the integration last week of Entergy’s transmission system and those of six smaller transmission owners.

PJM’s assessment for the 2013-14 winter months identified no reliability issues.

Last month's GridEX II security drill was a valuable test of PJM’s emergency response procedures but lacked in realism, participants said.

PJM will approve only one of 17 congestion relief proposals submitted in September, saying most failed to provide sufficient benefits or targeted problems that were already addressed.
