This report, conducted for the Northeast Energy Efficiency Partnerships, Inc. (NEEP) and its Evaluation, Measurement, and Verification (EM&V) Forum (hereafter EMV Forum or the Forum), summarizes the results of research on net and gross savings definitions, and the treatment of energy savings estimates in the policies of various entities in the Northeast. The research is intended to help NEEP and the Forum make progress toward the goal of improving and ensuring the understanding, transparency, and credibility of electric and gas energy efficiency resources implemented in the Northeast and mid-Atlantic region by addressing the following objectives:
- To increase clarity and regional consistency in the nomenclature used in describing and reporting modifications to estimates of gross savings from efficiency resources, specifically adjusted gross savings and net savings.
- To catalog and characterize policies in the region with respect to how net savings, adjusted gross savings, gross savings, and possibly other measures of efficiency impacts are used to develop and measure progress toward policy goals in order to help inform discussions about whether and how policy goals are aligned with policy metrics.
