In an effort to reduce wasted electricity and improve overall energy efficiency, the U.S. government instituted the Energy Independence and Security Act of 2007 (EISA 2007), which mandates motors manufactured after Dec. 19, 2010, have higher efficiencies than the previous standard, Energy Policy Act of 1992. This paper addresses two major concerns with the new efficiency requirements. This paper analyzes the cost-effectiveness of actual operation of electric motor-driven process equipment, and evaluates the economic difference of utilizing premium efficient versus standard efficient motors. The economic assessment includes the initial cost of standard versus premium efficient motors, as well as life cycle costs over the estimated motor life of 30 years. A separate economic evaluation of the impact of increasing power factor values is also performed using the same guidelines.
