4. Residential PLA Program 4 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. *The notes section contains a more detailed program description.

5. Residential PLA Program 5 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 mutually- acceptable suite of ENERGY STAR products in exchange for incentives, then work together to increase the market penetration of high efficiency products. Aggregation Negotiation Transformation Evaluation Ties program impact to changes in product assortments and marketing tactics Promotes retailer and manufacturer behavior change towards EE. May eliminate or reduce work papers with availability of category sales data Collaboration Platform Advantages Leading EEPS and retailers build national scale and address local market needs Reduces adminis- trative costs while significantly improving effectiveness Long-Term Vision: Nationwide ENERGY STAR ® Retail Products Platform

7. Residential PLA Program 7 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.

8. Residential PLA Program 8 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.
