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.

PJM will consider relaxing rules for up-to congestion transactions under a problem statement approved last week.

Combined cycle generators’ performance in providing Tier 2 synchronized reserve has fallen by half since 2008.

Retrofits and other planned outages will make it challenging to maintain reserve margins in 2014 and 2015 and PJM will likely need to reschedule some outage requests as a result.

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.

No one spoke up when Market Monitor Joe Bowring opened the floor to stakeholders in the Monitor's annual Advisory Committee meeting Friday. But Bowring and his staff took the opportunity to renew their case for eliminating “sham” scheduling and changing PJM rules on opportunity costs.

The Market Implementation Committee will consider changes to PJM’s real-time pricing mechanism, which RTO officials say is depressing energy and reserve prices.
