Cost Effectiveness Testing
Improving Efficiency Screening Practices throughout the United States
The National Efficiency Screening Project (NESP) is a group of organizations and individuals that are working together to improve the way that utility customer-funded electricity and natural gas energy efficiency resources are screened for cost-effectiveness.
The purpose of this project is to improve efficiency screening practices throughout the United States, and to help inform decision-makers regarding which efficiency resources are in the public interest and what level of investment is appropriate.
In 2014, NESP released The Resource Value Framework, a document that outlined a set of principles and best practices for screening energy efficiency. During the past two years, recommendations from the Resource Value Framework (RVF) have been used in a number of states to significantly improve cost-effectiveness testing methods.
NESP is currently working to create a National Standard Practice Manual for Energy Efficiency (NSPM) that will provide the principles, concepts, and techniques for sound, unbiased evaluation of energy efficiency and other demand side resources. The NSPM will update and expand upon the California Standard Practice Manual.
NESP currently has more than fifty organizations as members. It is coordinated by the Home Performance Coalition (HPC).
