In a significant move towards a sustainable energy future, Puget Sound Energy has announced a $10 million investment in Energy Northwest’s endeavors to develop new nuclear energy solutions. The collaboration, unveiled on Wednesday, aims to leverage advanced small nuclear reactors, specifically the X-energy Reactor Co.’s Xe-100, with the goal of producing electricity in Benton County, Eastern Washington, by the end of 2030. This strategic investment signifies a bold step towards meeting Washington state’s Clean Energy Transformation Act commitments, addressing the growing demand for reliable, carbon-free electricity while complementing renewable energy sources.

Context and Significance:
Puget Sound Energy, serving 1.2 million customers across Western Washington, is championing the cause of a clean energy future. Mary Kipp, the president of Puget Sound Energy, emphasized the need for reliable resources that produce energy without emitting greenhouse gases. The collaboration with Energy Northwest aligns with this vision, as the project aims to integrate advanced small nuclear reactors with renewables like solar and wind, ensuring a continuous and emissions-free power supply.

Energy Northwest’s Ambitious Goal:
Energy Northwest, operating the Columbia Generating Station since 1984, envisions adding up to 12 Xe-100 reactors, capable of generating 960 megawatts of electricity. The proposed site for these reactors, adjacent to the existing nuclear reactor in Eastern Washington, symbolizes a strategic expansion of clean energy infrastructure. Energy Northwest’s ongoing analysis of the viability of the X-energy project will guide future investments and lead to a final investment decision, emphasizing a measured and data-driven approach to the project’s development.

Advanced Nuclear Technologies:
The Xe-100 reactors represent a new era of nuclear energy, designed with simplified, standardized, and scalable features. Their integration with renewable sources offers a flexible solution, providing around-the-clock electricity without greenhouse gas emissions. This approach aligns with the broader goals of reducing reliance on traditional fossil fuels and transitioning to a more sustainable energy mix.

Meeting Clean Energy Targets:
Washington state’s commitment to transitioning its electric utilities to clean, renewable, and non-emitting resources by 2045 necessitates innovative solutions. Puget Sound Energy’s investment in next-generation nuclear technology underscores the recognition that, as the grid is decarbonized, new sources of carbon-free, reliable, and affordable electricity must be deployed. Energy Northwest CEO Bob Schuetz highlighted the vital role advanced nuclear energy can play in achieving these ambitious clean energy goals.

Accelerating Feasibility Studies:
Puget Sound Energy’s $10 million investment is intended to accelerate Energy Northwest’s examination of the feasibility of developing and deploying a next-generation nuclear energy facility. While the collaboration does not bind Puget Sound Energy to future financial commitments or signify ownership in a new nuclear project, it marks a critical milestone in advancing the dialogue around the integration of nuclear energy into the Pacific Northwest’s energy landscape.


Puget Sound Energy’s strategic investment in Energy Northwest’s pursuit of next-generation nuclear power represents a significant leap towards a sustainable and diversified energy portfolio in the Pacific Northwest. As the energy landscape evolves, this collaboration stands as a beacon of innovation, demonstrating that advanced nuclear technologies can be part of the solution in achieving clean energy objectives. The outcome of this venture could not only reshape the energy sector in the region but also serve as a model for other areas grappling with the complex challenge of balancing reliability, affordability, and environmental sustainability in their power grids.
