Production Tax Credit (PTC)

Definition: Provides the owner of a qualifying facility with an annual tax credit based on the amount of electricity that is generated. By focusing on the energy produced instead of capital invested, this type of tax incentive encourages projects that perform adequately. In 2007, the rate for the PTC was 1.9ยข/kWh. The PTC increases from year to year based on the consumer price index.
