Record Temperatures Spark Energy Conservation Requests

LCG, August 14, 2002-Both ISO New England and PJM Interconnection have asked customers to limit their electricity demand as forecasted temperatures reach record levels.

New England is expected to have record high electricity demand, as is the Mid-Atlantic region.

The transmission organizations, ISO-NE and PJM, have suggested methods by which customers can limit the chances of blackouts, such as using appliances in the evening and closing curtains.

PJM Interconnection, delivering over 71,600 capacity, serves parts of Pennsylvania, New Jersey, Maryland, Deleware, Ohio, Virginia, West Virginia, and DC.

The New England Independent System Operator (ISO) pools some 28,000 MW and serves New England states.
