The federal renewable electricity production tax credit (PTC) is a per-kilowatt-hour (kWh) tax credit for electricity generated by qualified energy resources and sold by the taxpayer to an unrelated person during the taxable year. Originally enacted in 1992, the PTC has been renewed and expanded numerous times, most recently by the American Recovery and Reinvestment Act of 2009 (H.R. 1 Div. B, Section 1101 & 1102) in February 2009 (often referred to as "ARRA") and the American Taxpayer Relief Act of 2012 (H.R. 6, Sec. 407) in January 2013.

The January 2013 legislation revised the credit by: (1) removing "placed in service" deadlines and replacing them with deadlines that use the beginning of construction as a basis for determining facility eligibility; (2) extending the deadline for wind energy facilities by one year, from December 31, 2012, to December 31, 2013; (3) extending the permission for PTC-eligible facilities to claim the Investment Tax Credit (ITC) through 2013 (also using the start of construction rather than placed-in-service date as a reference); and (4) revising the definition of the term "municipal solid waste" to exclude "paper that is commonly recycled and which has been segregated from other solid waste.” The definitional change for municipal solid waste applies to electricity produced and sold after the enactment date of the legislation (January 2, 2013) in taxable years ending after that date.

Credit Amount

The tax credit amount is $0.015 per kWh in 1993 dollars for some technologies and half of that amount for others. The amount is adjusted for inflation by multiplying the tax credit amount by the inflation adjustment factor for the calendar year in which the sale occurs, rounded to the nearest 0.1 cents. (For 2014, the inflation adjustment factor used by the Internal Revenue Service (IRS) is 1.5088.)

The table below outlines the credit amount as it applies to different resource types. The table includes changes made by H.R. 8 in January 2013, and the inflation-adjusted credit amounts are current for the 2014 calendar year, as published in the IRS Notice 2014-36.
