On July 17, 2013, the CPUC will hold a workshop to present the DEER 2013 and DEER 2014 update process and present an initial draft of the DEER 2013 update. This initial workshop will focus on the latest research available and proposed methodologies to use for the DEER2013 and DEER2014 updates, specifically:

  • DEER2013 mid-cycle updates will incorporate the codes and standards, including the California Title 20 Appliance Efficiency Regulations, the California Title 24 Building Efficiency Standards, and the United States Code of Federal Regulations, that become effective in January 2014 and will be applied to the 2013-14 portfolio cycle. Changes to weather input assumptions for the simulation models will also be included in the mid-cycle updates.
  • DEER2014 updates will be apply to the post-2014 portfolio, beginning in 2015, and will tentatively include measure cost updates, saturation and baseline studies, measure use profile updates, and any Evaluation, Measurement, & Verification study results available within the schedule.
