Integrated resource plan

The Integrated Resource Plan (IRP) is a forecast of conservation resources and supply-side resource additions that appear to be cost effective to meet the growing needs of our customers over the next 20 years.

We know these forecasts will change as the future unfolds and conditions change. Every two years, utilities are required to update integrated resource plans to reflect changing needs and available information. The last IRP was completed in 2017.

2019 IRP meeting schedule and materials

The 2019 IRP will be filed with the Washington Utilities and Transportation Commission on or before January 15, 2020.

The IRP Advisory Group (IRPAG) and the Technical Advisory Group (TAG) are teams of external stakeholders and regulators who meet to provide input during the integrated resource planning process. View the complete schedule of all IRP and TAG meetings.
