High efficiency motors save up to 30 percent in electrical costs as well as reduce heating loads. Providing a properly sized motor for the application allows the motor to run at nearly 100 percent efficiency levels. Underloading and overloading motors decreases efficiency. Using variable speed drives for large motors allows the motor to slow to meet the demand thus reducing energy consumption. In demand side management utility companies are working with consumers to reduce energy consumption and peak loading.
Incentives can be substantial.
Encouraging thermal storage and time-of day metering with rebates and lower rates helps shift electrical loads off peak periods. For residential customers, PSCo is providing compact fluorescent lights at a greatly reduced rate. Contact PSCo for more information. Specify high efficiency motors and variable speed drives. Become familiar with local utilities' demand side management programs, and take advantages of incentives and rebates.
