PJM Interconnection, which operates the grid serving 65 million people in Pennsylvania, 12 other states and the District of Columbia, said Wednesday that the company and its members are prepared to meet the forecasted winter electricity demand.
“Because of our members’ preparation efforts and history of reliable performance, improved coordination with gas pipeline operators, and the market’s ability and flexibility to call on a variety of resources, we’re confident that we will be able to meet customer demand this winter,” Michael E. Bryson, vice president of operations for PJM Interconnection, said.
PJM expects to have 185,611 megawatts (MW) of resources available to meet the forecasted peak demand of 135,506 MW.
PJM analyzes the anticipated electricity demand, weather predictions, and other factors to develop its forecast for winter operations. The organization also analyzes potential pipeline service disruptions and the effect on generators and has found that there are no associated reliability concerns for the coming winter. PJM noted that it also continues to test resources, conduct emergency procedure drills and survey generators for fuel inventory.
Climate models suggest a warmer season this winter, but studies of similar seasons suggest near- to below-average temperatures. The arctic air mass known as the polar vortex may also weaken later in the season, which could cause short periods of arctic cold.
Last winter’s peak demand, which occurred on Jan. 5, was 137,522 MW. PJM’s all-time winter peak of 143,295 MW was set on Feb. 20, 2015.
