Puget Sound Energy, Inc. (PSE) is a privately held energy utility based in Bellevue, Washington, serving more than 1.24 million electricity customers and approximately 881,000 natural gas clients throughout several counties in the Puget Sound area. Its service territory spans roughly 6,000 square miles.
Facilities
By the end of 2024, PSE's overall electric generation capacity reached nearly 6,524 megawatts (MW), with around 3,339 MW generated from assets owned directly by the company.
In 2023, the composition of PSE’s electricity generation included 30% hydroelectric power, 30% natural gas, 22% wind energy, and 18% coal. In alignment with the Washington Clean Energy Transformation Act, the company has been actively decreasing its reliance on coal. It discontinued purchasing coal-generated electricity from the Colstrip Generating Station—where it holds an approximate 25% ownership interest equating to about 700 MW. Attempts to divest this stake have been unsuccessful on multiple occasions.
PSE manages three hydroelectric facilities that collectively produce 236 MW: Baker River (170 MW), Snoqualmie Falls (44 MW), and Electron (22 MW). Its portfolio also includes significant natural gas-fired plants with a combined capacity exceeding 1,900 MW distributed across Whatcom, Klickitat, Cowlitz, Skagit, and Pierce counties. Notable stations in this category comprise Ferndale (270 MW), Mint Farm (310 MW), Fredonia (316 MW), and Frederickson combined-cycle plants.
The company’s wind power assets consist of Hopkins Ridge (157 MW), Wild Horse (273 MW), and Lower Snake River Phase 1 (343 MW), which together contribute a substantial portion of renewable energy capacity.
Additionally, PSE provides a net metering program that allows customers to supply surplus solar-generated electricity back into the grid. State-mandated energy efficiency initiatives are estimated to add roughly 1% annually to generation capacity by reducing demand.
Natural gas procurement primarily originates from suppliers located in western Canada and the Rocky Mountain region of the United States, ensuring consistent fuel availability for PSE’s customer base.
History
Formed in 1997 through the consolidation of Puget Sound Power & Light Company and Washington Energy Company, PSE’s heritage includes Puget Sound Power & Light’s origins dating back to the 1870s and its establishment of the first hydroelectric facility at Snoqualmie Falls in 1898. A prior merger attempt with Washington Water Power in 1952 was prevented by judicial intervention.
In 2007, PSE announced its acquisition by foreign investors led by Macquarie Group—an Australian asset manager—along with three Canadian pension funds. This prompted ballot initiatives in Island, Jefferson, and Skagit counties during 2008 to establish public utility districts (PUDs). Jefferson County voters approved their measure, resulting in a PUD formation in 2013 that compensated PSE $103 million for local utility assets.
The leveraged buyout by Macquarie and pension fund investors was completed in 2009. Puget Holdings, representing these stakeholders, merged with Puget Energy—the parent company of PSE—to create the existing corporate structure. Puget Energy is a holding company incorporated in Washington that operates through its regulated utility subsidiary, PSE.
Macquarie exited its ownership position in 2018. Present-day investors include Alberta Investment Management Corporation, British Columbia Investment Management Corporation, OMERS, and PGGM.
In 2020, PSE initiated construction on the Energize Eastside transmission line project, which has been subject to public controversy.
Clean Energy Transformation Act
In 2019, Governor Jay Inslee signed into law the Clean Energy Transformation Act, which requires utilities to eliminate coal usage by 2025, reach carbon neutrality by 2030, and operate with zero carbon emissions by 2045. Investor-owned utilities such as PSE are obligated to file a Clean Energy Implementation Plan (CEIP) every four years beginning in 2022. PSE’s first CEIP aims to achieve 63% renewable energy generation by the year 2025.
Rates and emissions
The average monthly residential electric bill for Puget Sound Energy customers consuming 1,000 kWh is $102.56, while the typical gas bill for 68 therms amounts to $86. In 2018, PSE disclosed carbon dioxide equivalent emissions totaling 10.5 million metric tons from its electricity services and an additional 5 million metric tons from natural gas operations, which corresponds to approximately 9 and 6 metric tons per customer respectively. According to EPA GHG MRR Subpart DD data, emissions per individual user stand at 0.169 metric tons.
