Introduction

The focus of this inventory, some of which has been placed into a searchable spreadsheet, is to support the National Energy Modeling System (NEMS) and to research cost information in state-mandated energy efficiency program evaluations – e.g., for use in updating analytic and modeling assumptions used by the U.S. Energy Information Administration (EIA). At EIA, NEMS is used in developing the Annual Energy Outlook (AEO) projections. NEMS is also used to prepare analytical studies for the U.S. Congress, the Executive Office of the President, other offices within the U.S. Department of Energy, and other Federal agencies. Outside EIA, NEMS is used by other nongovernment groups, such as the Electric Power Research Institute, Duke University, and Georgia Institute of Technology. In addition, the AEO projections are used by analysts and planners in other government agencies and nongovernment organizations.

These data, which have been used as a sampling source for EIA's purposes, support the EIA goal of quality improvement to maintain relevancy and consistency with changing energy markets and represent a limited sample of recent utility energy efficiency program evaluation, measurement and verification (EM&V) reports pertaining to residential, commercial, and industrial energy efficiency programs and measures. The intent of making this information available is to facilitate further research by enabling the rapid location and comparison of EM&V reports in terms of geography, scope, and other relevant characteristics. This inventory is national in scope with the exception of California, for which the CALMAC system provides a ready source for EM&V information. EIA does not plan to maintain this spreadsheet over time, so interested parties will need to verify any changes to EM&V documents or records status made after the spring of 2013.

Summary details

EIA reviewed and catalogued 329 data sources containing program evaluation results. These primarily were presented in 108 "Annual Reports" to commissions. An additional 115 reports were designated as "Impact" and/or "Process Evaluation" Reports. Thirteen documents reviewed were either applications for bill riders containing past evaluation results to support a utility's petition for billing rates, or program filings containing evaluation results to support the next program cycle. Two program websites are included (Louisiana Department of Natural Resources and Alabama Power) because they contained program results. The remainder of the documents is more generally designated as evaluation reports, EM&V reports, program results, or savings reports.

There is substantial research interest among the government and trade organization communities in state energy efficiency initiatives. The American Council for an Energy-Efficient Economy, the Consortium for Energy Efficiency, the Northeast Energy Efficiency Partnerships, and the Database of State Incentives for Renewables & Efficiency (DSIRE) website are just a few that monitor and actively contribute to the energy efficiency program arena.

Data collection approach

Electric and natural gas utilities, or sometimes government agencies or third-party entities, offer incentives and assistance through energy programs to eligible customers or constituents considering equipment installations or activities to reduce consumption of energy resources in their homes, buildings, and other facilities. These programs may be required by state regulation and enforced by a public commission, or they may be voluntary. EIA, through a contract with Science Applications International Corporation (SAIC), aggregated this EM&V information from primarily public sources.

To research U.S. efficiency program evaluation reports and related documents, this effort relied primarily on state regulatory authority websites and professional contacts with utilities around the country. In addition, EIA checked some utility websites for evaluation reports. Many public service commission websites also store all public records in docket databases. Recorded and associated State-level data EIA's data file contains recorded data fields most relevant to analyses on program information:

  1. Program Agency: Utility, government or third party agency undertaking the program and/or evaluation. Note that the agency delivering the efficiency program is not always the agency undertaking the evaluation.

  6. Report Date: Year of report issue.
  7. Report Contractor: Firm/agency contracted to deliver report. Note that not all reports could be linked to a contractor -- e.g., annual reports to commissions in PA are compiled from the EM&V contractor by the utility.
  8. Report Type: General type of document, e.g., Annual Report, EM&V Report, Impact Evaluation, Process Evaluation, Evaluation Results. Note that document types and purpose may overlap.
