NESP was formed in 2014 to bring organizations and individuals together with a common interest in improving cost-effectiveness assessment of publicly-funded energy efficiency and other DER investments. NESP’s publications and other resources include:

2014: The Resource Value Framework: Reforming Energy Efficiency Cost-Effectiveness Screening. NESP launched with the development of the first version of the Resource Value Framework (RVF) and supporting principles to guide cost-effectiveness testing for energy efficiency. The 2014 publication was developed through a two-year stakeholder process (prior to the formation of E4TheFuture) and was managed by Home Performance Coalition. The RVF authors included: Tim Woolf (Synapse Energy Economics), Chris Neme (Energy Futures Group), Pat Stanton and Steve Cowell (CSG), and Robin LeBaron and Kara Saul-Rinaldi (Home Performance Coalition). A panel of expert advisors reviewed multiple drafts and provided extensive commentary.

2017: The National Standard Practice Manual for Assessing the Cost Effectiveness of Energy Efficiency Resources (NSPM for EE) expanded upon the 2014 RVF by embodying the framework and principles and expanding the scope to include comprehensive guidance on BCA for efficiency resources. The NSPM for EE was developed, managed and funded by E4TheFuture, with support from the Energy Foundation. The authors included: Tim Woolf (Synapse Energy Economics), Chris Neme (Energy Futures Group), Marty Kushler (ACEEE), Tom Eckman (Northwest Power and Conservation Council), and Steve Schiller (Schiller Consulting), with input from an advisory group.

In 2020, the NSPM for EE was revised and updated to become the National Standard Practice Manual for Benefit-Cost Analysis of Distributed Energy Resources (NSPM for DERs). This new manual supplants the previous NSPM for EE, and contains new guidance for assessing other DERs including demand response (DR), distributed generation (DG), distributed storage (DS), electrification of buildings and vehicles, multi-DER projects such as grid-integrated efficient buildings (GEBs), and non-wires solutions (NWS).
