Energy Efficiency Cost-Effectiveness Testing

Gregory EhrendreichThe Midwest has a long and successful history of energy efficiency policies and programs. However, outdated cost-effectiveness testing approaches leave a lot of opportunities at the margins out of program portfolios. State regulators only approve efficiency programs that pass the state’s required cost-effectiveness test or tests, which measure the ratio of benefits to costs associated with an energy efficiency program.

Standardizing the methods and inputs for cost-effectiveness testing in a state helps to level the playing field among utilities, requiring them to count the same variables in the same way. The National Standards Practice Manual provides a framework for developing a primary test for a state or other jurisdiction from the regulator’s perspective that accounts for the energy policies and goals of that jurisdiction. This presentation will provide an analysis of existing Midwest cost-effectiveness tests, lost opportunities, the NSPM’s approach and case studies.
