Integrated Resource Plan

Mossyrock – One of Seven of Our Dams

The Integrated Resource Plan (IRP) is a tool to help Tacoma Power plan for an uncertain future so we can continue to meet our customers’ needs for decades to come. Approximately every four years, we complete a full refresh of the IRP. We also revisit and make small updates to the plan between the larger refresh years.

Public Input Process

We welcome input from our community and hold a public input process as part of the development of each IRP. Our 2020 IRP process centered around a series of four half-day workshops with a stakeholder working group between late February and late June. Workshops are now complete. Workshop materials and records are available below.
