- Hearing rate cases and approving rates and tariffs for the companies

- Reviewing, analyzing and hearing gas utility applications to pass-on wholesale cost increases in the cost of natural gas

- Reviewing integrated resource plans for large gas 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."
