An Overview of the Energy Independence & Security Act of 2007 (EISA)*

What is EISA?

The Energy Independence and Security Act of 2007 (EISA) was passed by Congress and signed into law on December 19, 2007. EISA builds upon the previous EPAct (Energy Policy Act of 1992) updating mandated efficiency standards for general purpose, three-phase AC industrial motors from 1 to 500 horsepower which are manufactured for sale in the United States. The U.S. Department of Energy (DOE) is responsible for establishing the rules to implement and enforce EPAct.

When is the effective date for EISA?

EISA applies to motors manufactured after Dec. 19, 2010. The Canadian version begins Jan. 1, 2011.

What are the efficiency standards under EISA?

For each general-purpose rating (Subtype I) from 1 to 200 horsepower that was previously covered by EPAct, the law specifies a nominal full-load efficiency level based on NEMA Premium® efficiency as shown in NEMA MG 1, Table 12-12. All 230 or 460 volt (and 575 volts for Canada) motors currently under EPAct, manufactured after December 19, 2010, must meet or exceed this efficiency level.

General Purpose Electric Motors (Subtype II) not previously covered by EPAct will be required to comply with Energy Efficient efficiencies as defined by NEMA MG 1, Table 12-11. The term "general purpose electric motor (subtype II)" means motors incorporating the design elements of a general purpose electric motor (subtype I) that are configured as one of the following:

  • U-Frame motor.
  • Design C motor.
  • Close-coupled pump motor.
  • Footless motor
  • Vertical solid shaft normal thrust motor (as tested in a horizontal configuration)
  • An 8-pole motor (900 rpm)
  • A poly-phase motor with voltage of not more than 600 volts (other than 230 or 460 volts)
  • Fire pump motors 1-200 HP
  • 201 - 500 horsepower motors not previously covered by EPAct will be required to comply with Energy Efficient efficiencies as defined by NEMA MG 1, Table 12-11

Are fractional HP and 48 or 56 frame motors included in EISA?

Only 1 - 500 HP motors with 3-digit frame NEMA numbers (143T-up) included in EISA. This also includes equivalent IEC frame designations (IEC 90 frame-up excluding 100 frame).

What Motors are not covered by EISA?

  • Design D with high slip
  • Adjustable speed with optimized windings
  • Customized OEM mounting
  • Intermittent duty
  • Integral with gearing or brake where motor cannot be used separately
  • Submersible motors
  • Single Phase motors
  • DC motors
  • Two-digit frames (48-56)
  • Multi-speed motors
  • Medium voltage motors
  • TENV and TEAO enclosures

Does EISA apply to every three-phase electric motor from 1 to 500 horsepower?

Not every configuration, but almost all motors except some special OEM designs with proprietary mounting configurations. The following motor configurations are exempt from EISA compliance:

  • Integral gearmotors
  • Integral brake motors
  • Inverter duty motors with windings optimized for ASD use that cannot be line-started
  • Design D high-slip motors

How do the efficiency levels of EISA compare to the efficiencies of Baldor's standard motors and Super-E® motors? 

Generally, the mandated efficiency levels of EISA for Subtype I motors fall at the present efficiencies of Baldor's Super-E® NEMA Premium® efficient motors for general-purpose 1 - 200 HP motors.

The Subtype II 1 - 200 HP and general purpose 201 - 500 HP motors may require Baldor to raise efficiency of some designs to comply with MG 1, Table 12-11; however, many Standard-E® designs presently comply. Super-E® motors will meet or exceed the EISA requirements for either of these motor types.

Does EISA apply to motors manufactured outside of the United States and imported for use?

Yes. The requirements of EISA include imported electric motors. This also includes the electric motors "as a component of another piece of equipment".

How about electric motors for export outside of the United States?

EISA does not apply to motors exported outside the United States, including motors mounted on equipment. The DOE will require these motors or their boxes to be specifically marked "Intended for Export". Countries outside of the United States are enacting their own Minimum Efficiency Performance Requirements (MEPS) that may require compliance.

Distributors or OEM's who sell these "intended for export" motors in the US will be subject to enforcement and penalties/fines from the U.S. Department of Energy.

Does EISA require any motors in use to be replaced?

No, EISA does not contain any requirement to replace electric motors in use.

How about electric motors in inventory?

EISA does not affect any inventories of electric motors. The law only applies to motors manufactured after December 19, 2010. Motors in inventory on that date can be sold or used as before the law.

Does EISA apply to rebuilt, repaired or rewound motors?

No, EISA only applies to new motors manufactured after the effective date.

Does EISA apply to both stock and custom motors?

Yes. EISA makes no distinction between stock or custom motors. The determining factor under EISA is whether a particular motor meets the law's definition of "electric motor". Stock and custom motors should be treated the same and follow EISA guidelines.
