PJM Interconnection ready to meet winter electricity needs

PJM Interconnection and its members are prepared to meet the forecast winter electricity demand across 13 states and the District of Columbia.

“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, and we collaborate with our generation and transmission owners to prepare for the most extreme cold weather scenarios.”

PJM forecasts peak demand at around 134,000 megawatts this winter and has more than 187,000 MW of resources that includes 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.

PJM also works with members to prepare for cold weather by testing resources, conducting drills and surveying generators for fuel inventory. PJM’s preparation checklist includes everything from increasing staffing for weather emergencies to maintenance activities to ensure equipment is ready for winter conditions.

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.
