Residential Appliance Saturation Survey

The California Energy Commission administered the 2003 Residential Appliance Saturation Survey (RASS), which was sponsored by five participating utilities: Pacific Gas and Electric (PG&E), Southern California Edison (SCE), Southern California Gas Company (SoCalGas), Los Angeles Department of Water and Power (LADWP), and San Diego Gas & Electric (SDG&E).

The RASS was performed with the objective of collecting four main categories of data:

• Saturation of residential appliances
• Characteristics of residential population
• Characteristics of dwelling units
• Patterns of electricity and natural gas consumption

This information is publicly available through Energy Commission publications below. Additionally, the results and reports can be downloaded from the KEMA website. The KEMA website also offers a way of interactively accessing the RASS database (21,920 customer responses) using standard queries. The link at the bottom of this page provides a link. Once you register you can produce two-dimensional reports using a variety of data sub-setting options.
