This report presents the Massachusetts Cross-Cutting Evaluation Team’s analysis of Non- Energy Impacts (NEI) attributable to 2010 commercial and industrial (C&I) retrofit programs administered by the Massachusetts Program Administrators (PA). Non-Energy Impacts include positive or negative effects attributable to energy efficiency programs apart from energy savings.

DNV KEMA embarked on this study to fulfill the directive set forth by the State’s Department of Public Utilities to update and improve non-energy impact estimates for use in the PA’s 2013 to 2015 energy efficiency three-year plan and future annual plans. In addition, the PAs will use this study to assist in program marketing, as NEIs increase the value proposition of Energy Efficiency programs for participants. The goal of this study was to provide a comprehensive set of statistically reliable NEI estimates across the range of C&I retrofit programs offered by the Massachusetts electric and gas PAs.

DNV KEMA identified the following objectives for this study:

  1. Quantify participant NEIs by gross NEIs per unit of energy savings separately for prescriptive and custom electric and gas measures;
  2. Examine the attribution rates of individuals who did and did not realize NEIs to inform the appropriate free-ridership rate for computing net NEIs; and
  3. Identify incidence of spillover, or energy savings resulting from program-influenced installation of energy efficiency measures that did not receive program incentives, by providing separate estimates for the incidence of “like” and “unlike” spillover.
