The Department of Energy is currently seeking to increase Minimum Efficiency Performance Standards (MEPS) for a narrow subset of electric motors which DOE has deemed "covered" by the rulemakings that implemented the provisions in the Energy Policy Act of 1992 and the Energy Independence and Security Act of 2007 (EISA). The current definition of covered motors leaves out a significant portion of the integral horsepower, poly-phase motor population in the United States. (The issue of determining that percentage will be discussed later.)
