The National Efficiency Screening Project (NESP) mission is to improve cost-effectiveness screening practices for distributed energy resources (DERs). NESP joins organizations and individuals with a common interest in improving the way that utility customer-funded energy efficiency and other DERs are assessed for cost-effectiveness and compared to other resource investments.

NESP is a stakeholder organization and is open to all organizations and individuals with an interest in working collaboratively to improve cost-effectiveness screening practices. To find out more about membership, and to join, see About NESP Membership.

E4TheFuture currently serves as coordinator of the National Efficiency Screening Project under the guidance of the Advisory Committee, and manages its publications. State implementation and use of the NSPM in jurisdictions is undertaken directly by interested stakeholders. E4TheFuture and foundation funding also provides technical support to states. Contact NSPM@nationalefficiencyscreening.org with any questions.

NESP’s publications include:

  • The Database of State Efficiency Screening Practices (DSESP)
  • May 2017 – National Standard Practice Manual for Assessing Cost-Effectiveness of Energy Efficiency Resources. This document (NSPM for EE) provides comprehensive guidance on developing a jurisdiction’s primary cost-effectiveness test using the Resource Value Framework and a set of universal principles, as well as other foundational guidance. Download the NSPM and supporting materials.
  • August 2014 – Prior to launching the NSPM project, NESP worked with stakeholders to develop the first version of the Resource Value Framework and supporting principles to guide cost-effectiveness testing. NESP’s work on the 2014 Resource Value Framework informs the NSPM guidance. For more information see Background.
