Puget Sound Energy Petition for Accounting Order UE-260113

Puget Sound Energy filed a petition with the Washington UTC seeking an accounting order that would authorize the utility's proposed treatment of costs associated with transmission network upgrades. The petition was filed on February 24, 2026, and remains pending as of the current docket status. Affected utilities and energy companies operating in Washington should monitor this proceeding as the outcome may establish precedent for how transmission upgrade costs are accounted for in ratepayer rates. The UTC has assigned staff lead Chris McGuire to review the petition, and a decision has not yet been issued.
