Firms have to pay workers the prevailing wage for their area and abide by rules for the use of apprenticeship programs.
The prevailing wage and apprenticeship requirements are needed for companies to receive the Advanced Energy Project Credit, the Alternative Fuel Refueling Property Credit, the Credit for Carbon Oxide Sequestration, the Clean Fuel Production Credit, the Credit for Production of Clean Hydrogen, the Energy Efficient Commercial Buildings Deduction, the Renewable Energy Production Tax Credit and the Renewable Energy Property Investment Tax Credit.
The prevailing wage stipulation is also required for the New Energy Efficient Home Credit and the Zero-Emission Nuclear Power Production Credit.
