Bill summary
The bill allows utilities to construct small modular reactors (SMRs) with a capacity up to 300 MW without a certificate of environmental compatibility from the state siting committee, provided they are colocated with an 'extra high load factor customer' in counties with fewer than 500,000 residents.
Utilities, large industrial electricity users, and residents in rural Arizona counties.
Utilities must provide 30 days' notice to the Corporation Commission and must ensure the reactor design is federally certified.
Cost impacts include potential savings for industry and utilities from streamlined permitting, but state agencies lose fee revenue associated with the certificate process.
Applicable upon enactment; however, the bill was vetoed.
Streamlined permitting for advanced nuclear energy, industrial power stability, and lower carbon baseload potential.
Significant loss of public input, reduced transparency in site selection, and weakened state-level environmental review.
The specific definition of 'extra high load factor customer' as determined by the commission and the total number of projects that might qualify under these exemptions.
