Bryson said PJM prepared for the season by studying "worst-case" scenarios such as the impacts of gas pipeline failures. (Natural gas is in higher demand in winter because of both its use for home heating and electricity generation.) PJM also worked with generation owners on cold weather preparedness, a fuel inventory survey, resource testing and a drill for emergency procedures. Communication and coordination between PJM and natural gas pipelines continues regularly throughout the winter.
Capacity Performance resources – generation, demand response and energy efficiency – must produce electricity when called upon regardless of weather or extreme system conditions. If they do not, they face significant non-performance charges. PJM procured Capacity Performance resources to meet more than 60 percent of expected needs. All resources will be required to meet Capacity Performance standards by June 1, 2019.
PJM expects to have 183,665 megawatts of electric resources to meet the forecasted peak demand of 135,548 MW. Last winter, when temperatures were milder than average, the winter peak of 130,680 MW was set on Jan. 19, 2016. PJM's all-time winter peak is 143,295 MW, set on Feb. 20, 2015.
