Winter Impacts of Energy Efficiency in New England

These savings provide significant benefit during periods of peak demand, such as the winter of 2014. In this analysis the effects of electric efficiency are estimated by comparing actual demand and prices during January-March 2014 (defined as winter 2014 in this report) with a scenario where demonstrated savings from electric efficiency programs are assumed not to exist. The resulting higher level of demand is then used to project what wholesale electricity prices and costs would be without energy efficiency.
