PJM expects to have 177 GW of resources with 131 GW of demand

PJM Interconnection (PJM) said Nov. 12 that it expects to have sufficient resources to meet forecasted demand for electricity this winter in its territory, which includes 13 states and Washington, D.C.

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

Meanwhile, PJM continues to implement the reliability lessons that it learned as a result of the so-called “polar vortex” a couple of winters ago.

The 2014-2015 winter peak use of electricity was 143,295 MW.  Although temperatures are forecast to be milder, PJM must be prepared for any periods of extreme cold that may occur.

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, the regional operator said in a news release.

“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.

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.

Communication and coordination between the natural gas and electric industries continues throughout the year and more frequently through the winter season. Last month, PJM and pipeline companies exchanged information relative to the upcoming expected winter operations.

PJM and the pipelines begin the season with monthly calls to discuss generation and transmission outages. Starting Nov. 1 through March, the calls are daily to discuss gas and electric grid system status.

PJM Interconnection, founded in 1927, ensures the reliability of the high-voltage electric power system serving 61 million people in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
