Puget Sound Energy said on October 7, 2026 that it has been awarded approximately $40.2 million from the U.S. Department of Energy for Project PULSE, a plan to raise the carrying capacity of transmission lines it already owns in King and Kitsap counties, Washington. PSE matches the grant with $40.2 million of its own, putting the total at about $80.4 million. The utility expects more than 153,000 customers to benefit, including Naval Base Kitsap and Seattle-Tacoma International Airport.
The money comes from a DOE Office of Electricity program called SPARK, short for Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades. DOE named 31 projects across 26 states on September 24, 2026. Those projects will receive $5.25 billion in total, $1.9 billion in federal funding from DOE and $3.35 billion in recipient cost-share funding. DOE expects the group to reconductor or rebuild more than 1,500 miles of line. It also expects grid-enhancing technologies across nearly 21,000 miles, which would free up over 23 gigawatts of capacity.
What the Money Buys
Project PULSE upgrades four existing 115-kV transmission line segments, about 23 miles, through advanced reconductoring. Two of those segments sit on the Kitsap Peninsula. The South Bremerton to Long Lake #1 line adds transmission capacity for South Kitsap. The second is the Kitsap to South Bremerton #1 line. PSE also plans 178 Dynamic Line Rating sensors along 323 miles of line across six Western Washington counties. Those sensors report real-time conditions. Operators can then rate a line by the weather it actually sees instead of a fixed seasonal assumption. PSE estimates more than $21 million of the investment goes to work in Kitsap County.
“This project will help us deliver more reliable power while moving more electricity across the transmission lines we already have,” said Mary Kipp, president and CEO of Puget Sound Energy. “We’re adding more capacity and flexibility to the grid while avoiding costly infrastructure upgrades.”
Why It Matters
SPARK is buying capacity by the mile of existing conductor rather than by the new corridor. PSE’s award shows what that looks like on one system: 23 miles of higher-capacity line and 178 sensors. It is aimed at a peninsula whose critical loads include a Navy base and a major airport. mgrid covered a comparable named SPARK award for the Kit Carson cooperative last month. The reliability case in both is concrete. The schedule is not. Nothing in either the PSE or the DOE announcement commits to an in-service date before 2027, and DOE has so far announced only an intention to fund.
Two dates in this announcement do more work than the dollar figure. DOE’s September 24 notice announced its “intention to help fund” the 31 projects. That is a selection, not an executed grant. PSE says Project PULSE is expected to be completed between 2027 and 2031, “pending finalization of the federal grant agreement.” So this buys a four-year build that has not formally started. PSE already describes load growth as constraining parts of its system.
The approach is the cheaper half of a familiar tradeoff. Reconductoring and dynamic line ratings extract more from existing rights of way. That is why DOE frames the program as a way to avoid greenfield construction and the multi-decade timelines new corridors carry. What it does not do is add a path. The constraint on the Kitsap Peninsula may be the number of lines into it rather than the rating of those lines. In that case a higher-capacity conductor moves the limit without removing it.
Critical Perspective
Neither PSE nor DOE has said how many megawatts Project PULSE actually adds. DOE’s program-level claim is over 23 gigawatts across all 31 selections, and PSE describes capacity constraints without quantifying the relief. The most important number in a transmission upgrade is therefore the one number missing from both announcements, which means the project cannot be checked against the national figure. The structure of the award invites the same question. PSE matches the $40.2 million federal grant with $40.2 million of its own, a regulated utility’s capital is normally recovered through rates, and neither announcement states a rate impact. Dynamic line ratings also deliver headroom conditionally. A line rated on real-time weather gains the most in cool or windy conditions and little on the hot, still days when the system is tightest.
