PENNSYLVANIA PUBLIC UTILITY COMMISSION Harrisburg, PA. Public Meeting held September 13, 2012 Commissioners Present: Robert F. Powelson, Chairman John F. Coleman, Jr., Vice Chairman Wayne E. Gardner, Commissioner James H. Cawley, Commissioner Pamela A. Witmer, Commissioner Implementation of the Alternative Energy Portfolio Standards Act of 2004: Standards for the Participation of Demand Side Management Resources – Technical Reference Manual 2013 Update Docket No. M-2012-2313373 M-00051865 2013 TRM ANNUAL UPDATE Tentative Order Table of Contents
limitations of studies were the duration of metering and number of loggers deployed, because shorter duration studies relied on extrapolation techniques and a smaller sample is considered less reliable. Based on the DOE and Wisconsin reports, it was determined that, in addition to geographical location, sample size and duration of metering were major criteria when reviewing CFL HOU studies. The SWE, PEG and Commission Staff reviewed metering studies from New England, California, Maine, Maryland, and North and South Carolina. The length of the study, number of homes, meters installed and geographical location of the study were all analyzed as part of the review. The California studies were included in the analysis because the sample sizes of these studies were much larger than all of the other studies. The 2010 California Study installed 7,299 light loggers. The next largest study reviewed was the 2005 California Study, which deployed 752 light loggers. The largest east coast study reviewed was the 2009 New England Study which collected data from 657 light loggers. The 2007 Maine and 2011 Maryland Studies were the only studies to report a higher HOU value than 2.8; however these two studies together deployed loggers in 84 homes compared to 1,780 homes collectively for the five other studies analyzed. In addition, the SWE, PEG and Commission Staff reviewed seven TRMs from other states and regions: Connecticut, Illinois, Maine, the Mid-Atlantic, New Jersey, New York and Ohio. Five of the seven states use a deemed HOU value for CFLs that is within 0.1 hours of 2.8. Based on this research and analysis, the Commission proposes revising the CFL HOU value to 2.8 for the 2013 TRM. The collective evidence supports an HOU value lower than 3.0. Specifically, five of the seven studies analyzed reported an HOU of 2.8 hours or less and five of the seven TRMs deemed an HOU value within 0.1 of 2.8. Furthermore, we find the 2.8 HOU from the 2009 New England Study significant, given
detailed above) into an average per-unit deemed savings value. The UEC itself is not equal to the deemed savings value, because the UEC model yields an estimate of annual consumption and not all recycled refrigerators would have operated year-round. In PY3, the Commission determined that the average removed refrigerator was plugged in and used 96.9% of the year. Thus, the deemed value the Commission proposes for the part-use factor is 96.9% based on PY3 data for all EDCs. The Commission proposes that the EDCs be allowed the option of calculating their own territory-specific part-use factor. In the event an EDC desires to calculate an part-use factor, the Commission proposes that, using participant surveys, EDC evaluators should determine the amount of time a removed refrigerator was plugged in. ii. Refrigerators Removed and Replaced If a refrigerator is removed and replaced with a new ENERGY STAR unit, the proposed annual savings are 533 kWh. If a refrigerator is removed and replaced with a new non-ENERGY STAR unit, the proposed annual savings are 417 kWh. The following methodology is used to calculate an energy savings value of 533 kWh for refrigerators that are removed and replaced with new ENERGY STAR refrigerators and an energy savings value of 417 kWh for refrigerators that are removed and replaced with new non-ENERGY STAR refrigerators: NET_kWhsaved Per Unit = DEEMED kWhsaved Per Unit – (REPLACEMENTUEC * PART_USE) Where: REPLACEMENTUEC = The annual unit energy consumption of the average replacement unit. This comes from the ENERGY STAR calculator and is equal to 416.600 kWh for a
