Energy Efficiency Resources
The Database for Energy Efficient Resources (DEER) contains information on selected energy-efficient technologies and measures. The DEER provides estimates of the energy-savings potential for these technologies in residential and nonresidential applications. The database contains information on typical measures -- those commonly installed in the marketplace -- and data on the costs and benefits of more energy-efficient measures. Energy-efficient measures provide the same energy services using less energy, but they usually cost slightly more.
Updates to the Database for Energy Efficiency Resources (DEER) have been developed by the California Public Utilities Commission (CPUC) with funding provided by California ratepayers.
The LED WRR disposition is added to the Non-DEER Work Papers page.
DEER2017 and DEER2018 values have been added to the ex ante database. See the update descriptions under the DEER Versions menu for more information.
Pursuant to Decision (D.) 13-09-023, Commission staff scored the utilities on their annual ex ante review performance as part of the Efficiency Savings and Performance Incentive. The final 2015 ESPI memos are published under the Energy Savings and Performance Incentive section under the main menu. Commission staff will be holding meetings with each utility to discuss the final scores.
