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

NESP’s publications include:

  • May 2017 – National Standard Practice Manual for Assessing Cost-Effectiveness of Energy Efficiency Resources. This document 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.

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, and manages its publications. State implementation and use of the NSPM in jurisdictions is undertaken directly by interested stakeholders. You may contact with questions.
