Massachusetts Program Administrators: Final Report - C&I Non-Energy Benefits

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.

Understanding Cost-effectiveness of Energy Efficiency Programs

This paper, Understanding Cost-effectiveness of Energy Efficiency Programs, is provided to assist utility regulators, gas and electric utilities, and others in meeting the 10 implementation goals of the National Action Plan for Energy Efficiency’s Vision to achieve all cost-effective energy efficiency by 2025.

This paper reviews the issues and approaches involved in considering and adopting cost-effectiveness tests for energy efficiency, including discussing each perspective represented by the five standard cost-effectiveness tests and clarifying key terms.

The intended audience for the paper is any stakeholder interested in learning more about how to evaluate energy efficiency through the use of cost-effectiveness tests. All stakeholders, including public utility commissions, city councils, and utilities, can use this paper to understand the key issues and terminology, as well as the various perspectives each cost-effectiveness test provides, and how the cost-effectiveness tests can be implemented to capture additional energy efficiency.
