Energy efficiency is widely recognized as a low-cost, readily available resource that offers a variety of benefits to utility customers and to society as a whole. There is a great amount of variation across the states in the ways that energy efficiency programs are screened for cost-effectiveness. As part of a webinar entitled “Strategies for Effective Regulatory Advocacy” hosted by Ceres on January 21, Tim Woolf spoke about the importance of properly implementing tests that capture the full value of efficiency resources. He highlighted best practices that enable states to address consumers concerns, properly valuate energy efficiency benefits, fully account for Other Program Impacts (OPIs) and environmental compliance costs, and ensure the economic effectiveness of key programs.
