The primary objective of these studies was to produce estimates of remaining potential energy savings for the near (2006-2008) and foreseeable (2009-2016) future through publicly funded energy efficiency programs in the existing and new residential, industrial, and commercial sectors.
These studies assess the remaining electric and natural gas savings potential in existing and new buildings in California until 2016 for the four California IOUs. In 2003, the CPUC set aggressive new energy and demand savings goals for the four IOUs based largely on the savings estimates from the 2002 and 2003 KEMA-Xenergy Potential Studies. These studies were designed to build on the previous studies, assessing the remaining potential using newly available input data on measure saturations, costs, and impacts; new building and appliance standards; and increased geographical disaggregation.
The findings will be used by the four California IOUs to focus utility program offerings by technology, sector, and climate zone. The results will help determine where potential savings remain and which technologies offer the most efficient opportunities for energy savings. The results will also help the utilities assess and meet the energy saving goals set by the CPUC.
This study incorporates the results of two other studies: an analysis of gross energy efficiency potential in existing industrial buildings conducted by KEMA, Inc., and a study of gross potential in residential, commercial, and industrial new construction conducted by Itron, Inc. under a separate contract.
