Costs and Benefits of Electric Utility Energy Efficiency in Massachusetts

Project completed August 2008.

Synapse assessed the benefits and costs of electric utility efficiency programs in Massachusetts. The types of benefits identified and assessed include, but are not limited to, avoided energy supply costs, demand-reduced-induced price effect, avoided CO2 costs, job creation, and risk reduction. As part of the analysis of utility program costs, the concept of conservation supply curve was explored and the costs of saved energy by Massachusetts utilities and several other utilities in other jurisdictions over many years were examined in detail. The study identified economies of scale in the cost of saved energy in every utility efficiency program, which is that efficiency program costs decreased when program scales expanded.
