EPACT  - ENERGY INDEPENDENCE AND SECURITY ACT 2007

The Energy Policy and Conservation Act (EPACT) which among other things, established energy efficiency levels for general purpose electric motors, has been amended by the Energy Independence and Security Act of 2007, which was signed by George W. Bush on December 19, 2007.

In part, this amendment establishes new, still higher, efficiency levels for electric motors effective December 19, 2010

As of that date, the energy efficiency levels known as EPACT levels will be raised to NEMA premium efficiencies.  These new efficiencies will apply to all general purpose 3-phase motors between 1 and 200 HP.  These are the motors that currently must meet EPACT efficiencies.

In addition after December 19, 2010, the following motors will have to meet the current EPACT efficiency levels.

This change involves general-purpose motors between 1 and 200 HP configured as follows:

U-Frame Motor.
Design C Motor.
Close-coupled pump motor.
Footless motor.
Vertical solid shaft normal thrust motor (as tested in a horizontal configuration).
8-pole motor
A poly-phase motor with voltage of not more than 600 volts (other than 230 or 460 volts.)
NEMA Design B motors between 200 and 500 HP.

OVERVIEW

SEC. 313. ELECTRIC MOTOR EFFICIENCY STANDARDS.

(a) DEFINITIONS.—Section 340(13) of the Energy Policy and Conservation Act (42 U.S.C. 6311(13)) is amended—

(1) by redesignating subparagraphs (B) through (H) as subparagraphs (C) through (I), respectively;
(2 ) and by striking (13)(A) and all that follows through the end of subparagraph (A) and inserting the following:

(13) ELECTRIC MOTOR.

(A) GENERAL PURPOSE ELECTRIC MOTOR  (SUBTYPE I)

The term ‘general purpose electric motor (subtype I)’ means any motor that meets the definition of ‘General Purpose’ as established in the final rule issued by the Department of Energy entitled ‘Energy Efficiency Program for
Certain Commercial and Industrial Equipment: Test Procedures, Labeling, and Certification Requirements for Electric Motors’ (10 C.F.R. 431), as in effect on the date of enactment of the Energy Independence and Security Act of 2007.

(B) GENERAL PURPOSE ELECTRIC MOTOR (SUBTYPE II)

The term ‘general purpose electric motor (subtype II)’ means motors incorp-porating the design elements of a general purpose electric motor (subtype I) that are configured as one of the following:

(i) A U-Frame Motor.
(ii) A Design C Motor.
(iii) A close-coupled pump motor.
(iv) A footless motor.
(v) A vertical solid shaft normal thrust motor (as tested in a horizontal configuration).
(vi) An 8-pole motor (900 rpm).
(vii) A poly-phase motor with voltage of not more than 600 volts (other than 230 or 460 volts.)

(b) STANDARDS.

(1) AMENDMENT. Section 342(b) of the Energy Policy and Conservation Act (42 U.S.C. 6313(b)) is amended

(A) by redesignating paragraphs (2) and (3) as paragraphs (3) and (4), respectively; and
(B) by inserting after paragraph (1) the following:
(2) ELECTRIC MOTORS.

(A) GENERAL PURPOSE ELECTRIC MOTORS (SUBTYPE I) .

Except as provided in subparagraph (B), each general purpose electric motor (subtype I) with a power rating of 1 horsepower or greater, but not greater than 200 horsepower, manufactured (alone or as a component of another piece of equipment) after the 3-year period beginning on the date of enactment of the Energy Independence and Security Act of 2007, shall have a nominal full load efficiency that is not less than as defined in NEMA MG–1 (2006) Table 12–12.

(delcted section on Fire Pump Motors)

(C) GENERAL PURPOSE ELECTRIC MOTORS (SUBTYPE II)

Each general purpose electric motor (subtype II) with a power rating of 1
horsepower or greater, but not greater than 200 horsepower, manufactured (alone or as a component of another piece of equipment) after the 3-year period beginning on the date of enactment of the Energy Independence and Security Act of 2007, shall have a nominal full load efficiency that is not less than as defined in NEMA MG–1 (2006) Table 12–11.

(D) NEMA DESIGN B, GENERAL PURPOSE ELECTRIC MOTORS.

Each NEMA Design B, general purpose electric motor with a power rating of more than 200 horsepower, but not greater than 500 horsepower, manufactured (alone or as a component of another piece of equipment) after
the 3-year period beginning on the date of enactment of the Energy Independence and Security Act of 2007, shall have a nominal full load
efficiency that is not less than as defined in NEMA MG–1 (2006) Table 12–11.

(2) EFFECTIVE DATE.—The amendments made by paragraph (1) take effect on the date that is 3 years after the date of enactment of this Act.
