The company that operates the power grid for New Jersey, Pennsylvania, Delaware and ten other states is asking all users to reduce power consumption between 3-7 p.m.

PJM Interconnection says the electricity demand spiked overnight and is likely to peak this afternoon. It is therefore asking everyone to cut back where they can. PJM has asked its power suppliers to be ready to provide electricity at “emergency levels” today.

PJM, based in Valley Forge, Pa., says power usage was so high earlier today it set a new wintertime record and another record may be set this afternoon. PJM says the conservation efforts will help ensure adequate power supplies for all of its customers. 

PJM manages the wholesale power supply for all or part of 13 states, which are New Jersey, Pennsylvania, Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, Ohio, Tennessee, Virginia, West Virginia and the District of Columbia.
