PJM and its members prepare to meet the demand for electricity in winter

VALLEY FORGE, Pennsylvania., November 4, 2021 / PRNewswire / – PJM Interconnection and its members stand ready to meet the demand for electricity expected this winter, using lessons learned from recent extreme weather events while taking into account recent fuel supply issues.

PJM, which operates the network in 13 states and the District of Colombia, expects to have over 185,000[1] MW of resources to meet the expected peak demand of approximately 133,000 MW. PJM’s all-weather winter peak is 143,295 MW, set on February 20, 2015.

“Maintaining the flow of electricity in the expected winter conditions is the main mission of PJM and our member companies,” said the President and CEO Manu asthana. “We understand the critical importance that electricity plays in the daily lives of the 65 million people we serve.”

Each year, PJM performs winter readiness assessments and exercises before the cold months. These assessments include collecting data on: fuel inventory, procurement and delivery characteristics; emission limitations; and minimum operating temperatures. PJM meets with federal and state regulators and neighboring systems to review winter preparations. PJM also holds weekly operational review meetings with major pipeline operators serving producers in PJM’s footprint to coordinate operations with the pipelines that supply a large portion of the gas production fleet.

This year, given the serious cold problems encountered in Texas during February 2021, PJM initiated a scan that resulted in many additional improvements to its winter preparation efforts. These improvements include:

  • Integrate critical load rules and business expectations into emergency operating procedures to help transportation owners identify and prioritize electrical service for critical facilities in the event of an emergency
  • Collect more information from suppliers on fuel, environmental or weather related limitations that could impact winter operations, while also including wind and solar generators in these requests
  • Further improve information sharing with the natural gas industry

In light of recent reports regarding the coal and fuel oil supply chains, PJM will continue to issue data requests for fuel inventories on a weekly basis to provide a clearer picture of fuel availability this winter. Additionally, in October, PJM made temporary changes to its emergency operations rules to give PJM and the generators more flexibility in building and maintaining the coal and oil supply in light of the current global shortages of these fuel stocks as winter approaches.

“We have been in close contact with the power producers in the PJM footprint to better understand their fuel supply situations, and this will continue throughout the winter,” said Mike Bryson, Senior Vice-President – Operations. “These improved and coordinated efforts have been incredibly helpful as we work with our stakeholders to ensure day-to-day reliability and a resilient system, even in the most extreme weather conditions. ”

PJM analyzes forecasted electricity demand, weather forecasts and other factors to develop its forecast for winter operations. PJM’s continuous readiness checklist for production and transportation owners includes everything from staffing up for weather emergencies to the maintenance activities required to prepare equipment for winter conditions.

PJM interconnection, founded in 1927, ensures the reliability of the high voltage power supply system serving 65 million people in all or part of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Colombia. PJM coordinates and directs the operation of the region’s transportation network, which includes more than 85,103 miles of transmission lines; operates a competitive wholesale electricity market; and provides for improvements in regional transportation expansion to maintain grid reliability and reduce congestion. PJM’s regional network and market operations generate annual savings of $ 3$ 0.2 billion to $ 4 billion. For the latest news on PJM, visit PJM Inside Lines at insidelines.pjm.com.
