On August 16, 2022, President Joseph Biden signed into law the Inflation Reduction Act of 2022 in what many have called the largest investment in climate change countermeasures in U.S. history.
The Inflation Reduction Act of 2022 is probably the most consequential climate change legislation ever enacted by the U.S. government—it certainly will be the most expensive—and accordingly, it will have a major impact on the renewable energy industry, mostly in the form of incentives and credits. Our team has reviewed the IRA’s 700-plus pages and brought together in this convenient guide all of the provisions relevant to the renewable energy industry.
IRA Renewable Energy Provisions
I. Clean Electricity and Reducing Carbon Emissions
Production Tax Credit (PTC) Extension/Modification (§13101)
- Extends the beginning of construction deadline for wind, biomass, geothermal, solar, landfill gas, trash, qualified hydropower and marine and hydrokinetic technologies from before January 1, 2022 to before January 1, 2025. Projects that were placed in service prior to January 1, 2022 remain subject to the existing PTC phaseout.
- Base credit for most technologies is set at 0.3 cents per kWh. Facilities that pay prevailing wages during the construction phase and the first 10 years of operation and meet apprenticeship requirements (the “Wage and Workforce Requirements”) are eligible for a PTC that is five times the base credit. There is an opportunity to cure Wage and Workforce Requirement deficiencies.
- Facilities with a maximum net output of less than one megawatt are also eligible for the five times base credit amount, as are facilities that began construction within 60 days after the Secretary of the Treasury publishes guidance on the Wage and Workforce Requirements.
- An additional bonus credit is provided for projects that meet a domestic content requirement that requires a certification that certain steel, iron and manufactured products used in the facility were domestically produced. This bonus credit is 10% of the credit amount.
- The credit amount is increased by 10% for facilities located in an energy community. An energy community is defined as being a brownfield site, an area which has or had significant employment related to oil, gas or coal activities, or a census tract or any adjoining tract in which a coal mine closed after December 31, 1999 or in which a coal-fired power plant was retired after December 31, 2009.
- Facilities financed by tax-exempt bonds will receive a reduction in the amount of credit.
- Extends the option to claim the ITC in lieu of the PTC.
Investment Tax Credit (“ITC”) Extension / Modification (§13102)
- Extends the beginning of construction deadline from before 2024 to before 2025.
- Sets a base credit rate at 6% for solar, fuel cells, waste energy recovery, combined heat and power and small wind property and 2% for microturbine property. These amounts are increased five times to 30% and 10%, respectively, if the Wage and Workforce Requirements are met. There is an opportunity to cure Wage and Workforce Requirement deficiencies.
- Extends credit for geothermal to construction beginning before 2035 (with phaseout beginning 2032).

The bonus credit amount is 2 percentage points, or 10 percentage points for projects that meet Wage and Workforce Requirements.
- Facilities financed by tax-exempt bonds will receive a reduction in the amount of credit.
- An additional credit is available to projects in an energy community. The additional credit is 10 percentage points for projects meeting Wage and Workforce Requirements or 2 percentage points otherwise. An energy community is defined as being a brownfield site, an area which has or had significant employment related to oil, gas or coal activities, or a census tract or any adjoining tract in which a coal mine closed after December 31, 1999 or in which a coal fired power plant was retired after December 31, 2009.
Bonus Credit Related to Low Income Communities (§13103)

- The provision extends the start of construction deadline to December 31, 2032.
- This provision modifies the amount of carbon oxide that must be captured to (i) 1,000 metric tons annually for direct air capture, (ii) 18,750 metric tons annually for electricity generating facilities (with the facility designed to capture not less than 75% of the baseline carbon oxide production or 60% in the event of an electricity generating facility not yet or only recently placed in service) and (iii) 12,500 metric tons annually for any other facility.
- The provision sets the base credit amount at $17 per metric ton for geological sequestration and $12 per metric ton for carbon oxide that is reused. These amounts are increased five times to $85 and $60 per metric ton if the facility meets the Wage and Workforce Requirements for the first 12 years of operation.
- The base credit rate for qualified direct air capture carbon oxide that is geologically sequestered is $36 per metric ton and $26 if the direct air captured carbon oxide is used in a qualified manner. These amounts increase five times to $180 and $130 if the project meets the Wage and Workforce Requirements.
- Facilities financed by tax-exempt bonds will receive a reduction in the amount of credit.
