APPENDIX 12C. NATIONAL SHIPMENTS ESTIMATES FOR SMALL ELECTRIC

MOTORS

March 24, 2008

12C.1 INTRODUCTION

Context:

The Department of Energy (DOE) is conducting an energy­efficiency standards

rulemaking for small electric motors. The purpose of this rulemaking is to evaluate energyefficiency standards for small electric motors. To complete this standard, DOE must estimate

potential energy savings from new standard levels imposed. To do this accurately, DOE usually

bases any energy savings on national shipment estimates provided by manufacturers. A request

was submitted by a DOE contractor to NEMA on December 7, 2007 to request shipment data for

this purpose. However, NEMA has not received adequate data from its membership and thus

DOE must pursue an alternate approach.

12C.2 METHODOLOGY

New Method Proposed:

For the Small Motors Determination Analysis published on July 10, 2006 (71 FR 38799),

NEMA provided shipment data on small electric motors to DOE. This data is now being used to

project an estimate of national shipments for 2007, instead of obtaining shipment specific data

from manufacturers. The result of this projection is shown on the attached pages. DOE invites

NEMA and/or its members to review and provide comment on this shipment estimate. Any and

all comment must be received by March 31, 2008, upon which time, the shipments estimate for

the ANOPR must be locked down. NEMA and its members will have an opportunity to

comment on the shipments estimate again once it is published by DOE later this year, however

for the purposes of completing the ANOPR analysis on schedule, DOE’s contractors must

prepare this estimate and finalize it by the 31st of March.

12C.3 REQUESTED ACTION

Action Required:

Please review the attached tables for reasonableness and comment by March 31, 2008.

12C.7 CSCR SHIPMENT FIGURES

Due to reporting policy guidelines, NEMA was unable to provide detailed shipment data on

Capacitor Start Capacitor Run (CSCR) shipments; however the Determination Analysis

published by DOE in 2006 indicates that approximately 5% of capacitor­start motor sales are

CSCR motors. Therefore, the estimate below simply uses a 19 to 1 ratio to scale CSIR units sold

to CSCR units sold.
