Low-carbon reliable energy standards-amendments.

Wyoming's SF 42 establishes new standards requiring utilities serving over 10,000 customers to generate a growing percentage of electricity from "dispatchable and reliable low-carbon sources" by 2038. It defines "low-carbon" as electricity meeting strict emissions limits (under 650 pounds of CO2 per megawatt-hour) and requiring 75% carbon capture from existing coal units or equivalent new sources. The bill allows utilities to recover compliance costs through a capped 2% surcharge on customer bills and mandates annual progress reports to the Public Service Commission. These changes directly affect Wyoming's major electric utilities and aim to balance emissions reductions with grid reliability.
