Power grid operator PJM Interconnection projects its members will be able to provide nearly 40% more electricity than the power grid operator expects to be needed this winter at peak demand, Kallanish Energy reports.
“We’re confident that PJM will be able to serve customer demand reliably this winter,” said Michael E. Bryson, senior vice president – Operations. “Our diverse resource portfolio, healthy reserves and strong-and-improving generator performance are assets in operating an efficient system … .”
PJM forecasts peak demand at roughly 134,000 megawatts this winter, and has more than 187,000 MW of resources that include natural gas, coal, nuclear, hydropower, wind, solar and other resources. PJM’s all-time winter peak is 143,295 MW, set on Feb. 20, 2015.
PJM analyzes the expected demand for electricity, weather predictions and other factors to develop its forecast for winter operations. The National Oceanic and Atmospheric Administration has predicted a warmer-than-average winter for much of the region PJM serves.
That region includes all or parts of 13 states and the District of Columbia, which contain 65 million people.
PJM also works with members to prepare for cold weather by testing resources, conducting drills and surveying generators for fuel inventory.
As part of its regular winter operations, PJM closely coordinates with natural gas supply and transportation across the region. In addition, PJM also studies unforeseen impacts of pipeline service disruptions and the effect on generators, and has found that there are no associated reliability concerns for the coming winter.
Last winter, PJM served a peak of nearly 139,000 MW on Jan. 31. Overall reliability was boosted by better generator performance, as outage rates plunged significantly from the 2013–2014 polar vortex.
