This report presents the results of an impact evaluation of Efficiency Maine Trust’s (EMT’s) Commercial Projects Grant Program for the 2010-2011 time period. The program provides competitive matching grants for custom electric and fossil fuel energy efficiency and renewable energy projects. The program was implemented in response to the funding opportunities made available from the American Recovery and Reinvestment Act of 2009, State Energy Program (ARRA-SEP). Funding of up to $50,000 per project was awarded through a competitive review and selection process conducted by EMT. The program disbursed $1.6 million through December 31, 2011 and is scheduled to be discontinued effective April 30, 2012.

Navigant Consulting, Inc. (Navigant) and Turner Building Science were selected by EMT to conduct an impact evaluation of the program results to date. Navigant’s scope of work focused on quantifying and verifying the energy savings and greenhouse gas reductions achieved by the program. This work explicitly did not include any process evaluation objectives. Specific research objectives included:

Measure and verify energy savings, including:

Site and source1 energy savings and greenhouse gas reductions for all projects
Fossil fuel savings, including fuel oil savings
Electric demand savings
Renewable capacity generation for renewable projects
Analyzing the attribution of impacts to the SEP/ARRA-funded grants to Commercial Projects and impacts on job creation
Analyzing the cost effectiveness of the individual projects and program overall according to the Maine TRC test and the U.S. Department of Energy (DOE) SEP Recovery Act benefit/cost test.
