CO HB1080

Requires the Colorado Energy Office director to conduct a feasibility study on using small modular nuclear reactors (rated capacity of 300 megawatts or less) as a carbon-free energy source in the state, with findings due to legislative energy committees by July 1, 2025.

Study must evaluate existing state laws that would need amendment, economic feasibility compared to retiring coal plants, safety and waste concerns, property tax benefits, job creation potential, and reliability/cost comparison with natural gas, wind, and solar energy.

Appropriates $250,000 from the General Fund to the Colorado Energy Office for fiscal year 2023-24 to implement the feasibility study.

Amends renewable energy standards law to increase the maximum nameplate capacity for pumped hydroelectricity qualifying as "recycled energy" from 15 megawatts to 400 megawatts, while keeping the 15-megawatt limit for other recycled energy sources.

Section requiring the feasibility study repeals effective September 1, 2026; the act takes effect 90 days after final adjournment unless subject to referendum petition and rejected at the November 2024 general election.
