2010-11 Motor Coalition Strategy
Determine and document a plan to improve the
efficiency of the greatest number of units providing the
greatest savings impact while reducing potential
enforcement issues while maintaining full product utility
for American industry
Deliver a plan to DOE as a platform for a consensus
recommendation that can be acted upon within the
least amount of time delivering large net benefits.
Move to a final rule with the least delay to deliver results
that save greatest energy as quickly as possible

Premise of the Extended Motor Product
Label Initiative (EMPLI)
An Extended Product Label provides a bridge
between component prescriptive incentives and
custom incentives for system improvements.
• Labeled product can be attributed deemed
savings—reduces evaluation costs
Therefore:
• Labeled product can receive prescriptive
incentives—reduces administrative costs

Current types of utility incentives
Prescriptive
 Utilizes product description and performance to prequalify items
to be incentivized
 Used to reach the most products and applications with the least
resource administration required
Quasi prescriptive
 Utilizes a deemed savings measure to evaluate a category of
product used in an more specific applications
 Requires a higher level of administration resource to evaluate
and qualify product based on performance label
Custom
 Requires before and post installation measurement to verify
savings
 Applicants may invest resources prior to confirmation of energy
savings to meet program requirements

Goals
Establish efficiency performance identification scheme
that meets power utilities requirements for incentive
programs
Define necessary measurement and verification
protocols
Describe products in a manner that can be readily
understood in their respective markets
Use trade association existing and proposed product

Share of 1-500HP
50 Million connected HP sold per year
All three of the driven loads [pumps, compressors and fans] are
currently going through DOE rule making process
Opportunity exceeds 10 million connected horse
power / year
Motor Summit 2014
The Association of Electrical and
Medical Imaging Equipment Manufacturers
Basics
Significant power utility funding is already available
[$7Billion]
Utilities need to find demand side programs that reach large
numbers of connected horse power without huge resource
needs and administrative costs to implement
Measurement & Verification steps will be addressed by each
product section [fans/pumps/compressors]
The coalition expects the results of this project to be usable
and accepted by a large number of potential utilities not
directly involved with the project
Each trade association expects to own and manage their
respective energy performance label
Motor Summit 2014
The Association of Electrical and
Medical Imaging Equipment Manufacturers
How does the coalition work?
Pick a representative team for each product that includes
representation from each perspective
Select a representative product from each group to be
developed in label
Elements of cost benefit analysis/work paper template
 Product label
• Test methods
• Metrics
• MEPS
Based on DOE rule
 Kwh saved by segment or product bin
 Site specific field testing [measurement and verification]
 Estimated administrative costs
Utilities will use results to build unique incentive programs for
respective service areas
Motor Summit 2014
The Association of Electrical and
Medical Imaging Equipment Manufacturers
What we expect to be accomplished
Trade associations will create the labels or marks identifying
their respective highly efficient products
Trade association may elect to include an MOU and license
agreement for their respective labels
Trade association will be responsible for any registration or
trade mark of their label
Co-branding with NEMA Premium may be an option
Labeled efficiency performance products will be marketed to
utilities/OEM’s/states/other trade associations and End
Users
Product labels provide a performance identifier to support
utility incentive programs requiring manageable
administrative costs
Motor Summit 2014
The Association of Electrical and
Medical Imaging Equipment Manufacturers
Conclusions
Working together using DOE rules
[test/metrics/MEPS] labels will accelerate
adoption rate of highly efficient extended
products
The results of this project can affect nearly
25% of the annual electric motor load in the
USA [10 million connected HP]
Wholesale promotion and funding by power
utilities of extend products can make this
program’s energy savings second to none
We can make a difference
