Manually initiated fast load control

Potomac Electric Power Company (Pepco) serves the District of Columbia and suburban areas of Maryland. It set a new peak load of 6140 MW on August 9, 2001. This presentation describes the load reduction programs of Pepco. The system marketed to residential customers consists of a radio controlled switch on air conditioners and a central control program to force a diversification of load control for those customers who choose the cycling program over the full reduction program. The radio controlled switch program is described here. Additionally, during emergency conditions, Pepco operates its voltage reduction program through a system of EMS controlled transformer taps with additional controls on certain distribution feeder equipment.
