Welcome to the Energy Efficiency Data Portal

This is the official public site for California investor owned utility energy efficiency program data. IOU-reported measure-level program tracking data are updated quarterly. The raw program tracking data is processed using the CET to calculate gross and net energy savings, demand reduction, emissions reductions, and cost effectiveness. Unscheduled updates may occur if merited upon data quality review. Reasons for potential updates include data true-up, new information, or user feedback. Evaluation updates are available upon completion of relevant studies and added to the public data sets (click here for data appendices from the 2010-2012 program evaluations.)

Program accomplishments are reported monthly, quarterly (fund shifting and other quarterly reports), and annually from 2006-present by program administrators.

Data are presented in graphical views in the Data Viewer and as downloadable Data Sets in spreadsheet formats described below.


The Data Viewer provides a platform to see savings for electricity and natural gas, demand reduction, emissions reductions, program expenditures and cost effectiveness. Users can filter by the total statewide portfolio or by IOU territory, as well as by program, market sector, measures, end use, and building type. All views are available as charts, time series, or geographically. Users may also filter for gross/net values, reported or evaluated (when available) and other factors. Data are categorized by program cycle, from 2010-2015.


These downloadable files contain various energy efficiency program data, including summaries of the quarterly energy efficiency program tracking claims and, when available, evaluation updates. All data have had personally-identifiable customer information removed. Each file contains a data dictionary and description of the level(s) at which data have been aggregated. Updated data sets are identified by date.
