Rochester Public Utilities hits new electric peak demand record

ROCHESTER, MN. — A combination of a string of hot days, population growth, and high air conditioning usage attributed to Rochester Public Utilities (RPU) hitting a new high for electric peak demand on July 18, 2006 at 276.5 MW (megawatts), breaking the old record of 263 MW set on August 9, 2005.

Electrical peak demand is the greatest amount of power used during a one-hour measured period. Peak demand usually occurs between 1 P.M. and 7 P.M. During times of high electric demand, we take measures to help alleviate the spike in demand at a certain point.

Through the RPU Partners program, we are able to cycle business equipment, large industrial equipment, and air conditioners that customers allow to be cycled if needed. By cycling the equipment for a 15 minute period, it helps to reduce the demand during our highest peak times. Also, by reducing the peak, there is less strain on generating facilities, which helps to save the environment and helps to conserve natural resources.

During peak times, customers are asked to make adjustments in their electricity consumption if possible. Use major appliances before 10 A.M. and after 8 P.M., set air conditioning at 78º F, and turn all unnecessary electric items off during the day.
