NERC: PJM Ready for Summer


The North American Electric Reliability Corporation, in a report this week, validated PJM’s ability to meet this summer’s expected demand while identifying potential issues for other regions in North America.

Each year, NERC’s Summer Reliability Assessment reports on the preparedness of regions across the U.S. and Canada to cope with upcoming hot temperatures. Together, 21 regional entities (including PJM) manage the reliability and security of North America’s bulk electric supply system.

Late last month, PJM announced it was ready to meet 2019’s expected summer demand for the 65 million people it serves in 13 states and the District of Columbia. From the Mid-Atlantic states to northern Illinois, PJM stands by with 183,454 megawatts of capacity committed through its markets for the summer months. This supply presents ample reserves to meet the expected summer peak demand of around 151,000 MW. PJM’s all-time highest power use took place in the summer of 2006 at 165,563 MW.

NERC’s independent, annual assessment counts PJM among the regional transmission operators prepared for the possible risks of higher-than-expected generation or transmission outages and demand.

“The landscape for summer 2019 looks similar to 2018, with more than enough anticipated resources and reserves to assure the reliable operation of the bulk power system in most assessment areas,” said John Moura, NERC’s director of Reliability Assessment and Technical Committees.

NERC pointed out some of the potential challenges elsewhere in the U.S. in the report.

NERC operates as an electric reliability organization to improve the reliability and security of the bulk power system in North America. To achieve that, it develops and enforces reliability standards, monitors the bulk power system and assesses future adequacy; audits owners, operators and users for preparedness; and educates and trains industry personnel.
