PJM Interconnection expects to have sufficient power this summer when power use can get as high as 155,553 MW, according to Electric Light & Power magazine. This compares to PJM's all-time peak demand of 163,848 MW. PJM serves 60 million people in 13 states and the District of Columbia.
To meet demand, PJM has available 186,884 MW of installed power generation capacity and 11,175 MW of demand response and energy efficiency. Demand response means there are customers who are paid to reduce their energy use at peak time periods on request and energy efficiency pays customers who modify their buildings to save electricity.
This amount of demand response and energy efficiency is about the same as the total amount of nuclear capacity in the state of Pennsylvania.
This year's summer forecast for power use includes East Kentucky Power Co-op (EKPC), which will be fully integrated into PJM on June 1, 2013. Together with EKPC, the anticipated demand growth from 2012 to 2013 is 0.9 percent, slightly lower than normal due to the continuing effects of the slow economy.
PJM Interconnection, founded in 1927, ensures the reliability of the high-voltage electric power system serving 60 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. PJM coordinates and directs the operation of the region's transmission grid, which includes 59,750 miles of transmission lines; administers a competitive wholesale electricity market; and plans regional transmission expansion improvements to maintain grid reliability and relieve congestion.
