SECOND ATOMIC AGE

Zero Emission Credit

ZEC

State-issued credit for zero-emission nuclear generation, compensating plants for environmental value. Example: Illinois ZECs paid $16.50/MWh through 2032.

ZECs subsidize nuclear to prevent retirements, with auctions setting prices. Illinois program preserved 2.2 GW capacity; similar in New York. They stack with RECs and PTCs for total revenue.

Why it matters now

ZECs stabilize nuclear fleets in 2025-2026, enabling restarts for hyperscaler deals. They bridge to federal PTC amid SMR licensing and HALEU constraints.
