Nuclear Production Tax Credit (PTC)

Definition. A federal tax credit for existing US nuclear generators introduced in the Inflation Reduction Act of 2022. The credit is paid per MWh produced and scales inversely with wholesale power prices — generators get more credit when prices are low, less when prices are high. Effectively a floor on cash flow.

Mechanics

Base credit: $15/MWh, indexed for inflation.
Phase-down: starts ramping down when "gross receipts" per MWh exceed $25, fully phases out around $43.75/MWh in real terms.
Bonus credit: +5× if prevailing-wage and apprenticeship requirements met (largely applicable to refurbishment, less to existing operations).
Available 2024-2032 under original IRA framework.

Why it matters

The PTC effectively underwrites the existing US nuclear fleet through a decade in which: - Solar/wind continue depressing wholesale prices in many ISOs. - Some nuclear plants might otherwise face uneconomic operation despite their capacity value.

For CEG specifically, the PTC means that if the AI-power-demand thesis is wrong and wholesale prices fall, downside is cushioned. If the thesis is right and prices rise, the PTC fades but is replaced by higher market revenue. Asymmetric for the generator.

2025 update — OBBBA preserves the PTC

The "One Big Beautiful Bill Act" (OBBBA, 2025) rolled back many IRA energy provisions but preserved the nuclear PTC. This is bipartisan: nuclear is one of the few energy technologies with consistent support across both parties (Democrats for emissions, Republicans for industrial base + grid reliability).

How CEG benefits

CEG's 10-K (FY2025) cites the PTC as a contributor to "stable, predictable cash flows that support our business strategy." The exact PTC contribution to EPS is not separately disclosed but is estimated in the low single-digit dollars per share — meaningful relative to ~$10-12 normalized EPS.

Falsification

Repeal or material narrowing would be a thesis-level event: - Would compress nuclear-generator margins by 5-15% depending on power-price environment. - Falsifier T001-F5 ("Repeal of nuclear PTC") tracks this. - Watch federal tax legislation, FERC dockets, and political shifts that could threaten the consensus.
