Incentives Available in U.S. States & Territories

The DSIRE home page features a U.S. map for easy access to incentives and policies available in each state. Clicking a state or territory provides a list of available incentives and policies in that state, organized into two categories: (1) Financial Incentives and (2) Rules, Regulations & Policies.

  • The incentive or policy type (e.g., tax credit, rebate program, net metering)
  • The implementing sector (e.g., federal, state, utility)
  • Eligible sectors (e.g., residential, commercial, government)
  • Eligible technologies (e.g., solar water heating, wind energy, insulation)
  • Links to authorizing statutes, regulations and relevant legal documents
  • A summary of the incentive or policy
  • A link to the incentive or policy web site
  • Contact information

Established in 1995, the Database of State Incentives for Renewables & Efficiency (DSIRE) is an ongoing project of the North Carolina Solar Center and the Interstate Renewable Energy Council (IREC). It is funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), primarily through the Office of Planning, Budget and Analysis (PBA). The site is administered by the National Renewable Energy Laboratory (NREL), which is operated for DOE by the Alliance for Sustainable Energy, LLC.
