Integrated Resource Planning
Planning is integral to everything we do at Avista, and it is especially important in determining how to meet the future energy needs of our customers. Central to this effort is a process called the Integrated Resource Plan, or IRP. You can think of the IRP as a roadmap for how we will meet the energy needs of our customers 20 years into the future using a diverse energy mix.
Having a diverse energy mix is the foundation of Avista's ability to provide our customers with clean, reliable power at fair, reasonable rates. Our diversified energy portfolio ensures we have a stable supply of power around the clock, every day of the year, today and into the future.
As a regulated electric and natural gas utility, Avista files IRPs every two years with the public utility commissions in Washington, Idaho and Oregon where we serve customers.
An important part of the IRP process is public involvement. Two key opportunities for public involvement are through the Technical Advisory Committee, or TAC, and the public comment period.
The TAC is committee of stakeholders who meet to review specific issues and aspects of the IRP. During this approximately 18-month IRP process, the TAC will meet six times, with each meeting being an intensive, full-day session. The TAC is a diverse group of representatives.
When the IRP has been drafted, the Washington Utilities and Transportation Commission and the Idaho Public Utilities Commission will each hold open comment periods when the public is invited to review the plan and provide comments to the respective agencies.
Avista submitted the 2017 Electric IRP to the Idaho and Washington Commissions on August 31, 2017. If you are interested in joining the TAC and participating in the development of the 2019 IRP, please email John Lyons or contact him at (509) 495-8515. You can also contact him with questions about previous IRPs.
