Energy Efficiency

California has led the nation in energy efficiency programs since the 1970s. Due to the state’s efficiency programs, per capita energy use has remained flat, while the rest of the US has increased by about 33 percent.

The CPUC regulates ratepayer-funded energy efficiency programs. The CPUC works with the investor-owned utilities, other program administrators, and vendors to develop programs and measures to transform technology markets within California using ratepayer funds.

2015 Potential Study Draft Results and Comments Webinar - April 21, 2015


Staff will be hosting a webinar on April 21, Tuesday to provide a venue to discuss comments to the 2015 Potential Study draft results. The goal of the webinar is to have a venue for stakeholders to see the comments from all stakeholders grouped by topic (e.g. Res/Com, AIMS, modeling, etc.). The webinar will also be a venue for stakeholders to elaborate on their comments if they feel necessary. In addition, the CPUC and Navigant will provide some initial responses to the comments. Please understand the scope of the discussion will focused on existing comments about the draft results and technical topics. Any big picture policy issues will be deferred to the formal proceeding and formal comment period. Staff and Navigant may not have responded to all the comments by the date of the webinar but will do the best to provide feedback.
