PJM: Sufficient Electricity Supplies to Meet Winter Demands

PJM and member companies have sufficient resources to meet forecasted demand for electricity this winter, according to PJM staff.

PJM expects to have 177,628 megawatts of electric capacity resources available to meet the forecasted demand of 131,720 MW, which does not include the expected reduction from demand response.

Last winter, 2014-15, peak use of electricity was 143,295 MW.  This year, although temperatures are forecast to be milder, PJM must be prepared for any periods of extreme cold that may occur.

“PJM has taken many steps to reinforce generator readiness and to continue to improve coordination with natural gas pipelines, a key source for a large portion of the generation fleet,” said Michael Kormos, executive vice president and chief operations officer for PJM.

PJM continues to work with its members to test equipment and procedures, ensure adequate fuel supplies and coordinate with the natural gas industry to better align electric and gas operations for winter.

To prepare:

  • PJM studied the impact of higher load levels, higher generator outage rates, as well as a combination of these scenarios and their impacts on the power system.
  • PJM studied the impact on the transmission system of severe gas availability issues that can affect generator availability.
  • PJM makes winter generation testing available to generating units that have not run in the eight weeks prior to Nov. 1, on either primary or alternate fuel.
  • Generators have also completed a fuel inventory survey to assess their fuel supply status.
  • Recently, members and natural gas industry representatives met with PJM to exchange information.

Communication and coordination between the natural gas and electric industries continues throughout the year and more frequently through the winter season. PJM and the pipelines begin the season with monthly calls to discuss generation and transmission outages. From November 1 through March, the calls are daily to discuss gas and electric grid system status.
