State Implementation Plans

State Implementation Plans are a policy vehicle that allow states and municipalities to receive emission reduction credit for wind power purchases. Under guidance issued by the U.S. Environmental Protection Agency in August 2004, States and municipalities can receive emission reduction credit in their State Implementation Plans for wind power purchases that reduce air emissions and help achieve attainment of the National Ambient Air Quality Standard for ozone. The National Renewable Energy Laboratory has developed model State Implementation Plan documentation to assist states in achieving this objective. For more information on State Implementation Plans, please see the following publications.
