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!

QUESTIONS (click to collapse section)

What does DSIRE offer?

The DSIRE web site provides summaries of renewable energy and energy efficiency incentives and policies established by the federal government, state governments and U.S. territories, local governments, and larger electric and gas utilities in the United States. DSIRE also offers summary maps and summary tables, and a search tool to help users determine which incentives and policies apply (or might apply) to a specific project. The search tool allows users to search for relevant incentives and policies by state, incentive type, technology type, implementing sector and eligible sector.
What types of renewable energy incentives and policies are included in DSIRE?

DSIRE provides summaries of incentives and policies established by the federal government, state governments and U.S. territories, local governments, and larger electric and gas utilities in the United States. Incentives and policies that support renewables are divided into two groups: 

  • Financial Incentives include a variety of tax incentives, grants, loans, rebates, industry recruitment/support, performance-based incentives, green building incentives, and certain other types.
     
  • Rules, Regulations & Policies include public benefits funds, renewable portfolio standards, net metering, interconnection standards, solar/wind access policies, contractor licensing, equipment certification, solar/wind permitting standards, building energy codes, energy standards for public buildings, and certain other types.

The DSIRE Glossary provides a description of the types of incentives and regulatory policies included.

The DSIRE Glossary provides a description of the types of incentives and regulatory policies included.

What types of federal incentives are included in DSIRE?

Federal incentives included in DSIRE are generally limited to those available on an ongoing basis to consumers, businesses and other end-users. DSIRE does not include federal funding opportunities for research & development, demonstration projects, outreach, or inter-governmental programs.
Does DSIRE distribute news?

Yes! The DSIRE staff publishes a free monthly newsletter that summarizes new incentives and policies, and changes to existing incentives and policies. Subscribe to this newsletter here.

We also distribute news via Twitter and Facebook. (Look for the small logos near the top of this page.)

Does DSIRE track incentives and policies for all utilities?

DSIRE tracks relevant incentives and policies for all investor-owned utilities (both electric and natural gas) in the United States. Because there are thousands of electric cooperatives and municipal utilities in the United States, DSIRE's scope is generally limited to those with more than 30,000 customers. (If your utility is relatively small, contact your utility directly to find out if any incentives are available.)
Does DSIRE track incentives and policies for all cities and counties?

No. DSIRE provides information on approximately 250 incentives and policies established by local governments (excluding municipal utility incentives and policies). Because there are tens of thousands of local governments in the United States, DSIRE's scope is generally limited to local incentives and policies that are especially innovative, and to municipalities and counties with the largest populations.
How can I use DSIRE to search for incentives for a specific type of project, such as solar water heating or insulation?

Use the Search DSIRE tool on the DSIRE home page. This tool allows users to search for relevant incentives and policies by state, incentive type, technology type, implementing sector and eligible sector.
How can I find out which states have established a certain type of incentive or policy, such as a tax credit or a renewable portfolio standard (RPS)?

For a quick overview of the availability of a specific type of incentive or policy in the United States, see DSIRE’s Summary Tables and Summary Maps. Or, use the Search DSIRE tool on the DSIRE home page. This tool allows users to search for relevant incentives and policies by state, incentive type, technology type, implementing sector and eligible sector.
How often is DSIRE updated?

DSIRE is currently undergoing a transition and operating with a significantly smaller staff. During this time, we are unable to provide the same level of content review our users have come to expect over the 17-year history of DSIRE. We will continue updating the incentives and policies in DSIRE on a daily basis, but certain incentives may not be reviewed within the 12-month time frame that had become our standard. In the meantime, if you find that a policy or incentive summary in DSIRE has inaccurate information, please refer to the question below, and let us know.
Is there an international version of DSIRE?

In collaboration with the U.S. Department of Energy, India’s Ministry of New and Renewable Energy, and the U.S. National Renewable Energy Laboratory, staff from DSIRE and North Carolina State University supported the development of an Indian version of DSIRE. The beta version of the Indian Renewable Energy and Energy Efficiency Policy Database (IREEED) can be found at http://www.ireeed.gov.in/. For information about policies and incentives in other countries, these sites could be useful:
