This article by Navigant's Frank Stern, published by Association of Energy Services Professionals, considers whether utility program evaluation skills are applicable to evaluating the impacts of renewable energy programs. They may apply in the case of distributed renewables, but utility-scale renewables are less likely to require similar types of program evaluation. One issue related to utility-scale renewables that has required program evaluation skills is attribution, but obtaining necessary information through interviews with developers may require different skill sets. The author concludes that program evaluators must understand how the markets for renewable energy and energy efficiency differ.
