Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter A — Determination of Tax Liability › PART IV — CREDITS AGAINST TAX › Subpart D — Business Related Credits › § 45J
Pays a tax credit of 1.8 cents for every kilowatt-hour of electricity a company makes at an eligible advanced nuclear power plant during the first 8 years after the plant first starts operating, as long as the power is sold to someone not related to the seller. The credit for any one plant is limited by a national cap of 6,000 megawatts that the Treasury Secretary must allocate. The yearly credit for a plant also can’t exceed a share of $125,000,000 based on that plant’s allocated megawatts out of 1,000. The credit is cut back if the reference market price (defined elsewhere in the tax code) for the year is more than 8 cents per kWh; the cutback scales up to when that price is 11 cents, and the 8-cent threshold is adjusted for inflation and rounded to 0.1 cent. The Secretary must write rules, including a certification process, within 6 months after this law or any change to it. Any unused portion of the 6,000 megawatt cap after December 31, 2020 must be reallocated quickly first to plants placed in service on or before that date that didn’t get full allocations, then to later plants in the order they come in. One-line definitions: Advanced nuclear power facility — a plant owned by the taxpayer that uses nuclear power and was placed in service after the law took effect and before January 1, 2021. Advanced nuclear facility — a reactor design approved after December 31, 1993. Qualified public entity — a federal, state, or local government unit, certain co-ops, or certain nonprofit rural utilities. Eligible project partner — a designer, builder, supplier, financier, or owner that worked on the plant. Qualified public entities may elect to let an eligible project partner claim the credit instead, with special partnership and timing rules that follow the tax code. Some other technical rules like those in section 45(e) also apply.
