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 253 pertains to Integrated Resource Planning. It states: "Any utility serving in Wyoming and required to file an integrated resource plan (IRP) in any jurisdiction, shall file that IRP with the Wyoming Public Service Commission. The Commission may require any utility serving in Wyoming to prepare and file an IRP when the Commission determines it is in the public interest. Commission advisory staff shall review the IRP as directed by the Commission and report its findings to the Commission in open meeting. The review may be conducted in accordance with guidelines set from time to time as conditions warrant."
