S. 448

Credit Incentives for Resilient Critical Utility Infrastructure and Transformers Act or the CIRCUIT Act This bill expands the advanced manufacturing production tax credit to include up to 10% of the cost to produce transformers that have an input voltage of 34.5 kilovolts or less, have an output voltage of 600 volts or less, and are rated for operation at a frequency of 60 hertz (i.e., distribution transformers). As background, the advanced manufacturing production tax credit (part of the general business tax credit) allows a tax credit for certain component parts (e.g., battery cells, solar modules, and inverters) and critical minerals (e.g., aluminum, lithium, and nickel) that are produced in the United States or a U.S. possession and sold generally to an unrelated third party for use in clean energy equipment. (Some exceptions apply.)
