Retail Plug Load Portfolio (RPP) Concept
What is the Retail Plug Load Portfolio?
• RPP is a portfolio approach to addressing plug load and
appliances program design with the ultimate goal of reducing
unit energy consumption of products sold through retail.
Short term trial objective
• Motivate participating retailer to promote and sell more
efficient models.
Longer term objective
• Motivate retailers to regularly demand, stock, and promote the
most efficient models available from their manufacturer
partners.

Long-Term Vision: Nationwide ENERGY STAR®
Retail Products Platform
Vision: Transform the way energy efficient products and energy efficiency
messages are delivered to residential customers using an omni-channel retail
approach.
Concept: Leading Program Sponsors and Retailers negotiate a mutuallyacceptable suite of ENERGY STAR products in exchange for incentives, then
work together to increase the market penetration of high efficiency products.

How Savings Will Be Measured
•
Historic sales
used to project
sales-weighted
unit energy
consumption
(“SWUEC”)
baseline moving
forward
(“forecasted
SWUEC”) for
each product
category.
•
Future sales
used to create
“recorded
SWUEC.”
•
Program effects
(“net effects”) is
the difference
between the two.

The Challenge with the Ex Ante Review Process
• DEER isn’t populated with values for key
parameters for many products in the RPP product
suite such as hours of use, IMC, and EUL.
• DEER is updated once every three years, too
infrequently to accommodate the fast evolution of
many of the products in the RPP product suite.
• The work paper approval process does not balance
the cost effectiveness of research to verify energy
savings estimates and other key parameters with
resulting value of energy savings. This is uniquely
problematic for products with very low per-unit
energy savings and rapidly-evolving product
cycles.

Our Requests to Cal TF
1. Review Cal TF Workpaper ABSTRACT_Retail Plug
Load Portfolio Program.
2. Critique the methodology to estimate unit energy
consumption (UEC) in Calculation Methodology
for Sales-Weighted Unit Energy Consumption
Estimates in the Retail Plug-Load Portfolio (RPP)
Program.
