VALLEY FORGE, Pa., Jan. 8, 2014 /PRNewswire/ -- PJM Interconnection, the electric grid operator for more than 61 million people in 13 states and the District of Columbia, has ended its special request for the public to conserve electricity. The call to reduce electricity use was prompted by the intense cold weather.
The request to reduce electricity use had applied to the entire region served by PJM.
"Our thanks go to all of the consumers who heeded our call yesterday to conserve electricity," said President and CEO Terry Boston. "Consumers' conservation had a direct impact on our ability to meet everyone's electricity needs and helped us manage a very tight power supply caused by the extreme cold across all 13 states."
PJM broke the record for peak winter electricity use twice on Tuesday from the previous peak of 136,675 megawatts in 2007. (One megawatt is enough to provide power for about 1,000 homes.) Yesterday's morning electricity use peaked at 138,000 MW and in the evening at 141,312 MW.
Conditions were challenging for the grid due to the extreme cold in the past two days, a number of generating plant outages as well as increased demand for electricity to meet consumers' heating needs. The generating plant outages were mostly related to the weather. Outages due to natural gas curtailments were a relatively small percentage of the total outages. Despite the challenges, PJM was able to meet demand without interruption.
