· IE2 by June 16, 2011
· IE3 by January 1, 2015 (for motors >=7.5 kW, or IE2 with an adjustable-speed drive)
· IE3 for all motors by January 1, 2017 (or IE2 with an adjustable speed drive).
The new MEPS will supersede the existing voluntary 1999 European Committee of Manufacturers of Electrical Machines and Power Electronics EFF1, EFF2, and EFF3 efficiency standards.
Adoption of the MEPS by the European Commission will put them on a path similar to that taken by the United States in the Energy Independence and Security Act (EISA) of 2007 (PDF 151 KB).

This act increases the U.S. MEPS for 1- to 200-horsepower, 1,200, 1,800 and 3,600 RPM general-purpose motors from the Energy Policy Act of 1992 Energy Efficient (IE2 equivalent) levels to NEMA Premium Efficiency (IE3) levels by December 2010. EISA also establishes an Energy Efficient (IE2) level for motors with output power ratings of 201 to 500 hp.
For additional information, you can purchase the new IEC standard on motor efficiency classes, or download the Motor MEPS Guide (PDF 4.2 MB). Download Adobe Reader. Also, watch for the IEC 60034-31 Guide for the Selection and Application of Energy-Efficient Motors Including Variable Speed Applications, which will be available soon.
