The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

DSIRE' s Quantitative RPS Data Project provides quantitative information about state renewables portfolio standards (RPS). In the DSIRE RPS Data Spreadsheet, state requirements are defined by year and by resource class and include other key data elements such as monetary penalties or alternative compliance payments, eligibility of new and/or existing facilities, the percentage of the state's electric load covered by the policy, comments to clarify data entries or assumptions, and an update memo to describe recent changes to the data. The DSIRE RPS Field Definitions document contains detailed descriptions of the data fields in the DSIRE RPS Data Spreadsheet and how they are organized. The most current versions are located directly below while past versions are available in the Archive section. This project began in 2008 to support analysis efforts at the National Renewable Energy Laboratory (NREL).

Separately, Lawrence Berkeley National Lab (LBNL) has allowed DSIRE to publicly post the data that it has assembled on state level compliance with RPS mandates. The LBNL RPS Compliance Data Spreadsheet details annual state RPS obligations (MWh) and RPS achievement (% of obligation) for both overall state standards and solar or distributed generation set asides. It also includes notes describing the sources of the data and how the calculations were made for each state.
