The Commission regulates four investor owned electric utilities that operate in Wyoming. In addition, the Commission also has regulatory authority over eighteen retail rural electric cooperatives that provide electric service within the state.
The PSC has the following primary duties regarding the regulation of electric utilities:
Integrated Resource Plan (IRP) Filings
An Integrated Resource Plan (IRP) is a recurring planning process undertaken by a public utility to identify the preferred mix of supply and demand side resources that will meet projected customer demand, provide service reliability and resource diversity at the least possible cost.
Commission Rule Chapter 3, Section 33 - Integrated Resource Plan (IRP) pertains to Integrated Resource Planning. It states: "Each utility serving in Wyoming that files an IRP in another jurisdiction shall file that IRP with the Commission. The Commission may require any utility to file an IRP."
