As PSE works to meet statutory clean energy obligations outlined in Washington’s Clean Energy Transformation Act and aspires to be a Beyond Net Zero carbon company by 2045, Montana can continue to play a strategic role by providing a diverse supply of clean, reliable and renewable energy. To meet the anticipated energy needs of the region in the coming years, PSE will continue to acquire new sources of energy.


As part of this clean energy transition, PSE has invested funds to partner with Montana energy producers and continues to seek additional opportunities to acquire clean energy resources to supply demand.


In December 2021, we submitted our first Clean Energy Implementation Plan (CEIP) that seeks to move PSE to 63 percent clean electricity by end of 2025 (up from 34 percent in 2020). To deliver this increase over the next four years, our CEIP must be approved by our regulator, the Washington Utilities and Transportation Commission (UTC).

“This is an important step forward in diversifying our regional economy, creating new jobs and bolstering local tax revenues for our schools, roads and county services. This is a Made in Montana solution.”

-Bob Lee, Rosebud County Commissioner

In 2021, PSE signed a 20-year power purchase agreement to add 350 MW of wind energy from the Clearwater Wind Project, based in Rosebud, Custer, and Garfield Counties. 

From the middle of November 2022 through the end of March 2023 the Clearwater Wind project operated at an average capacity factor of over 50%, delivering valuable energy to PSE’s system and customers. This production coincided with a period of cold winter temperatures, increased electricity demand, relatively low production from PSE’s wind facilities in Washington, and extraordinarily high market power prices. Energy delivered from Clearwater Wind during this period reduced PSE’s power supply costs for our customers by approximately $51 million dollars.

This power purchase agreement is one example of PSE’s ability to provide a long-term commitment and investment into Montana’s innovative energy economy. As PSE works to meet our aspirational goals of being a Beyond Net Zero Carbon company and the requirements of Washington State’s Clean Energy Transformation Act, Montana can continue to play a strategic role in supplying a diverse supply of clean, reliable, and renewable energy.

About Clearwater Wind Project:

  • Phase 1, which is operational now, consists of 365 MW of renewable energy. The entire wind project will be capable of generating up to 750 MW of clean energy  – enough to power approximately 140,000 households a year.

  • The wind project spans three counties: Rosebud, Garfield and Custer.

  • Clearwater Wind is creating local employment opportunities – including up to 350 construction jobs and approximately 20 full-time operational jobs. 

  • The full project is also expected to deliver substantial economic benefits to the region, providing more than $400 million in support through jobs, additional tax revenue and landowner payments.

In 2020, Puget Sound Energy signed a hydroelectric PPA with Energy Keepers, Inc. the tribally owned corporation of the Confederated Salish and Kootenai Tribes in Montana. The Selis Ksanka Qlispe hydroelectric project, located at Flathead Lake in Montana, is the first tribally owned hydroelectric dam in the U.S. Through this agreement, PSE is set to purchase 40 megawatts of zero carbon energy produced by the Selis Ksanka Qlispe hydroelectric project. 

This historic agreement runs through 2035, significantly supporting Montana's workforce and energy economy while fostering new partnerships and resource innovations.


PSE’s mission is deep decarbonization, reducing greenhouse gas emissions and transforming its business to deliver on the objectives of Washington’s Clean Energy Transformation Act and its Beyond Net Zero Carbon aspirations. PSE will be coal free by 2025 and its electric system will be carbon neutral by 2030. Learn more here >>>
