REPiS is a database developed and recently updated by the National Renewable Energy Laboratory (NREL) with funding from the U.S. Department of Energy. REPiS provides information on renewable energy plants and installed capacity for energy planners, policy makers, and others interested in renewable energy. Originally created in 1984 and now updated through 2002, REPiS contains information on operating as well as planned renewable energy units. It covers the following types of renewable energy technologies: biomass, geothermal, hydroelectric, photovoltaics, solar thermal, and wind.

The data in REPiS comes from publicly available sources, such as federal and state government publications and reports; trade association data sources; trade press literature such as weekly newsletters; and personal communications with industry and government officials. No surveys are conducted to collect data. Information in the database is collected through an extensive literature search. The data represent our "best efforts" at compiling and verifying an inventory of all known U.S. grid-connected renewable electric facilities.

NEW: REPiS Maps and Charts

These downloadable files, which offer a visual representation of capacity numbers from the REPiS database, are offered in two formats below:

Capacity Maps (as of August 2003)
  • Slides (MS Powerpoint 1.6 MB)
    Slides of shaded U.S. maps representing renewable capacity by technology (installed and planned)

  • Spreadsheets (MS Excel 807 KB)
    Source data for slideshow map images, includes the maps of U.S. renewable capacity by technology (installed and planned)
Capacity Charts (as of August 2003)
  • Slides (MS Powerpoint 471 KB)
    Slides of charts representing the cumulative renewable capacity by technology (installed and total planned)

  • Spreadsheets (MS Excel 285 KB)
    Source data for slideshow chart images, includes the charts of cumulative renewable capacity by technology (installed and planned)

UPDATED: REPiS 7.0 (Interim Update) is Now Available for Download

This download of REPiS includes significant update of all renewable technologies through year 2002. For this update process, information has been collected from various sources, such as energy newsletters, other databases, utilities, websites of energy companies, and personal contacts. State energy agencies have been contacted to verify the new data, and they are providing feedback to the best of their knowledge.

The database contains information on nearly over 115,000 MW of renewable energy generation capacity connected to the utility grid. This includes 2,725 MW that went on-line during 2000 through 2002. In addition, this update includes just over 7,500 MW of capacity additions being planned for 2003 and beyond. Please note that there are 7 states we have not yet received feedback from. These states are: Alaska, Delaware, Illinois, Maine, Maryland, New Jersey, and South Dakota,. The data for these seven states are not included in this update. The REPiS website will be further updated to reflect the feedback received from these states as they become available.

REPiS: Renewable Electric Plant Information System,
1999 Edition

This technical report presents some of the results from the REPiS database, and offers a perspective on how electric restructuring may affect electric power data collection, and therefore how future editions of REPiS could be conducted.

Section II summarizes, in aggregate, data on the operational status by renewable energy technology.

Section III breaks out the REPiS data by technology and discusses market trends over time for each technology, and some of the contributing policy and market factors.

Section IV provides data on planned renewable energy units.

Section V highlights the 10 states with the most renewable energy capacity and non-hydro renewable energy capacity, respectively.

Section VI compares the data in this edition of REPiS with the 1994 edition of REPiS and with data on renewable electric technologies maintained by the U.S. Energy Information Administration.

Section VII discusses how changes in data collection and availability, in response to electric industry restructuring, may affect future editions of REPiS.
The report ends with a summary.
