Heimdall Power and Puget Sound Energy Launch Landmark DLR Project

‍Heimdall Power is proud to announce a groundbreaking project with Puget Sound Energy (PSE), the largest energy utility in Washington state. In what marks the largest deployment of dynamic line rating (DLR) sensors in the United States, Heimdall Power is installing 75 Neurons across 100 miles of transmission lines in five counties in western Washington.

Installed largely by Heimdall Power’s proprietary autonomous drone system, real-time data from the Neurons will empower PSE to dynamically rate its transmission lines, maximize existing infrastructure, and enable more efficient, reliable power delivery to its more than 1.2 million electric customers.

“This technology gives us much more insight into all the factors that influence how much power can flow on our lines,” said Michelle Vargo, PSE’s Senior Vice President of Energy Operations. “It provides more flexibility in how we manage system load and more strategically select future investments.”

Over the coming weeks, Heimdall Power will complete installations across Washington’s Pierce, Kitsap, King, Island, and Whatcom Counties. Puget Sound Energy will evaluate the system through summer 2026, using the insights from the pilot to guide future grid planning and the wider implementation of DLR technology across its network.

“The energy challenges we face demand solutions that can deliver impact today while building the foundation for tomorrow,” said Jørgen Festervoll, CEO of Heimdall Power. “PSE is meeting those challenges head-on by unlocking new capacity, strengthening communities, and pioneering a smarter, more resilient grid that puts PSE’s customers first.”
