Applying motors as a means to reduce electrical energy demand

Motor Facts Industrial motors can have a 20 to 30 year service life The average IHP motor is repaired 3 or more times in it’s life [ source EASA ] The average IHP motor uses 4 to 6 times it’s original cost in electricity per year Current Epact regulations covers less than 75% of motors sold today Environmental groups estimate over 5 million units are repaired each year

EISA Basics EISA is the acronym for the Energy Independence & Securities Act This law was signed on December 19, 2007 and will be enforced beginning on December 19, 2010 On December 19, 2010, motor manufacturers may not build motors that have a lower nameplate efficiency than the rules allow. Motors that are considered “finished goods” or are shipped from the factory before December 19, 2010 can be sold after December 19, 2010 because they were built before the deadline.

General Overview of EISA Levels General Purpose motors that today need to meet EPACT, will need to meet the NEMA Premium efficiency levels in 2010 General Purpose motors that were exempt from EPACT because of voltage, mounting, etc will need to meet EPACT in 2010 Motors that cannot be used in most applications, such as special shafts, blowers or nonstandard frequencies, are exempt from any regulations for efficiency.

Specific EISA Rules Exempt / Not Covered Single phase Special shaft extensions TEBC, TEAO, DPFV, TENV Special V/Hz inverter motors Non-continuous duty Design D Phase converters Multi-speed 50Hz Two-digit frames (48, 56) Must meet EPACT (Table 12-11) Close Coupled Pump Vertical Solid Shaft Round body Nonstandard Voltages, 60Hz 200-500hp Firepump motors U-frame Must meet NEMA Premium (Table 12-12) 1-200hp Design A & B C-face, D-flange Footed Voltages covered by EPACT (60Hz) Note: Frame size is not an exemption. If a motor is an IEC frame, follow the rules just as if it was a NEMA Frame. If a motor is above a NEMA frame (680), follow the rules just as if it was a 440 frame.

What is pending? ….“Crush for Credit”

Crush for Credit Rebate Proposal APPLICATION—To be eligible as required one must have demonstrated evidence that the entity purchased an electric motor to replace an installed motor removed the installed motor the entity from service; and properly disposed the installed motor of the entity; and the physical nameplate of the installed motor of the entity. AUTHORIZED AMOUNT OF REBATE—The Secretary may provide to an entity that meets each requirement under paragraph (1) a rebate the amount of which shall be equal to the product obtained by multiplying the nameplate horsepower of the electric motor purchased by $25.00. PAYMENTS TO DISTRIBUTORS OF QUALIFYING ELECTRIC MOTORS—To assist in the payment for expenses relating to processing and motor core disposal costs, the Secretary shall provide to the distributor of an electric motor described in sub section 1 (1), the purchaser of which received a rebate under this section, an amount equal to the product obtained by multiplying the nameplate horsepower of the electric motor and $5.00. AUTHORIZATION OF APPROPRIATIONS—There are authorized to be appropriated to carry out this section, to remain available until expended— (1) $80,000,000 for fiscal year 2010; (2) $75,000,000 for fiscal year 2011; (3) $70,000,000 for fiscal year 2012; (4) $65,000,000 for fiscal year 2013; (5) $60,000,000 for fiscal year 2014.’’.

Federal Rebate for NEMA Premium® Motors Included in Senate Energy Bill Crush for Credit Federal Rebate for NEMA Premium® Motors Included in Senate Energy Bill Released from NEMA March 31, 2009 By unanimous support, Senator Blanche Lincoln (D-AR) successfully offered the amendment to the Senate's draft comprehensive energy bill. This legislation creates a new energy-efficient motor rebate program for the purchase of NEMA Premium® efficiency electrical motors. Specifically, this program provides a $25 per horse-power rebate for the purchase of NEMA Premium motors, as well as a $5 per horse-power rebate for the disposal of the old inefficient motor. This program is needed to offset the cost difference between new, more expensive, efficient motors and the lesser cost to repair the older, more inefficient motors. Once signed into law, this program allows the federal government to spend $350 million to incentivize the wide-spread adoption of NEMA Premium motors. (1) for the purchase and installation of a new electric motor that meets the applicable standard described in section 342(b); and (2) to replace an installed motor of the entity that does not meet the applicable standard described in section 342(b)
