Electrical Demand Control for Industry

have the potential to reduce their maximum peak dmand charges without sign$imntly afecting production. Working toward greater electrical tlCficiency will not only reduce your plant’s power costs but will also help your electric utility provide more efficient serdce at lower rates. This Technology Update helps you identijij whether your plant has the potential for reducing maximum demand and describes various demand control methods. Industrial plants normally have electrical loads that vary both daily and seasonally. For plants with a connected load of more than 35 kW, a demand meter is used to establish the 15to 30-minute maximum demand within a billing period. The demand charge reflects the peak rate at which electrical energy is consumed and is higher when there is more electrical equipment running.
