Database of Screening Practices

The DSP provides information regarding state cost-effectiveness screening practices for ratepayer funded electric and natural gas energy efficiency programs. States can use the DSP to learn about other states’ practices, and to readily access and better understand policies, processes, and studies that support assumptions (and underlying methodologies) used by states in their benefit-cost analyses (BCA). The DSP can also help to identify where and how states are using the National Standard Practice Manual to guide their BCA practices.

About the Database

  • The DSP (v1) launched in October 2018 as an Excel-based database. In August 2020, the database (DSP v2) migrated to Tableau for an improved user interface.
  • The DSP is a living document, containing information from 52 jurisdictions (50 United States, Washington D.C., and Puerto Rico), that is updated regularly. The database was last updated April 1, 2021.
  • DSP content is based on the best available information at the time of research, including on-line research and interviews with state regulatory staff and others.
  • If you have questions, or identify data or links that may be incorrect or require modifications/updates, please contact:

DSP (v1) was created and populated by Synapse Energy Economics, with input from ACEEE and several NESP Advisory Group members. 

DSP updates and v2 migration were managed by Alaina Boyle, E4TheFuture project manager, with support from Devin Hubbard and Aisha Tipnis, E4TheFuture interns. E4TheFuture appreciates the interns’ excellent work managing/developing the Tableau version. Many thanks also to v2 reviewers for helpful feedback: Tanuj Deora, Uplight; Greg Ehrendreich, MEEA; and Grace Relf, ACEEE.

Users interested in learning more about benefit-cost analysis can view the National Standard Practice Manual for Benefit-Cost Analysis of Distributed Energy Resources. Appendices include detailed guidance on valuation of relevant impacts (Appendix C), presenting test results (Appendix D), traditional cost-effectiveness tests (Appendix E), discount rates (Appendix G), and other efficiency-specific information (Appendix H).
