Avista has filed its 2014 Natural Gas Integrated Resource Plan (IRP) with state regulators in Washington, Idaho and Oregon. The plan forecasts sufficient natural gas resources well into the future, indicating that access to natural gas supply through the acquisition of additional pipeline resources will not be needed until 2034 or later.

The IRP is submitted to the public utility commissions every two years as part of Avista's regulatory commitment. Each IRP is a thoroughly researched, data-driven document that looks into the projected future energy needs of customers and determines the most effective plan of action for reliably meeting those energy needs. In addition to Avista's professional energy analysts, a Technical Advisory Committee that includes public utility commission staff, peer natural gas utilities, customers, and other stakeholders participated in the development of the IRP.
