Renewable Energy Tax Credits

Iowa Code Chapter 476B establishes a state production tax credit of 1.0¢ per kilowatt-hour (kWh) for energy generated by qualified wind energy facilities and sold or consumed on-site. The total nameplate generating capacity of all facilities qualified for the tax credits is 50 megawatts (MW). The program capacity limit has been reached. The tax credit certificates are transferrable and may be applied toward the state's individual income, corporation income, franchise, insurance program, sales and use, or replacement tax.

Iowa Code Chapter 476C establishes a state production tax credit of 1.5¢ per kWh for energy sold by eligible wind energy facilities and certain non-wind renewable energy facilities. For eligibility applications filed after July 1, 2011, tax credits are also available for on-site consumption of renewable energy from facilities with a nameplate capacity of not less than 750 kW.

The total nameplate generating capacity of all facilities eligible for the 476C wind tax credits cannot exceed 363 MW. The total nameplate generating capacity of all facilities eligible for the 476C non-wind tax credits cannot exceed 63 MW.  Of the 63 MW total, 10 MW are reserved for solar facilities with a generating capacity of one and on-half MW or less that are owned or contracted for by a municipal utility, a rural electric cooperative, or an investor-owned utility. For non-wind facilities seeking eligibility on or after July 1, 2011, applications are limited to facilities with a nameplate capacity of 60 MW or less, and total eligibility for each non-wind facility is limited to 10 MW. The tax credit certificates are transferrable and may be applied toward the state's individual income, corporate income, franchise, insurance premium, sales and use, or replacement tax.

To qualify for the tax credits, wind and other renewable energy facilities must first receive a preliminary eligibility determination from the Iowa Utilities Board.
