Seattle City Light Requests Additional Time Extension for Boundary Hydroelectric Project

Strategic Insights -

Seattle City Light, a Washington-based energy utility company, has submitted a request to the Federal Energy Regulatory Commission (FERC) for an additional time extension to complete revised exhibits for the Boundary Hydroelectric Project. The request is primarily driven by the need to correct modifications made to Spillway No. 1, which were part of efforts to reduce total dissolved gas levels. The company initially determined that these changes did not warrant updating Exhibit F, but more recent assessments revealed the importance of revisions to accurately reflect the project's modifications.

Key Takeaways:

  • Seattle City Light submitted a request to FERC for a time extension until December 1, 2025, to complete revised exhibits for the Boundary Hydroelectric Project.
  • The requested time extension is aimed at allowing sufficient time for a full review of the project's modifications, including corrections to Spillway No. 1 and minor updates to Exhibit F.
  • The company initially determined that Exhibit F did not require updating for minor recreation amenities changes, but later realized that the exhibit included drawings showing modifications that have since been removed.
  • City Light plans to make small updates to Exhibit F simultaneously with the corrections to Spillway No. 1.
  • The Boundary Hydroelectric Project is subject to the terms and conditions outlined in the License Order, issued on March 20, 2013.
  • The project has undergone several time extensions, including a previous extension granted by FERC on March 15, 2024.

Statistics:

  • The Boundary Hydroelectric Project has undergone multiple time extensions, with the initial extension granted in March 2024 and the second extension requested in February 2025.
  • The project's construction includes the development of a fish hatchery, recreation facilities, and wildlife habitat lands, as required by Forest Service Conditions in Appendix A.
  • Article 303 of the License requires the submission of revised Exhibits A, F, and G within 90 days of project completion.
  • The requested time extension will allow City Light to complete the revisions to Exhibit F by December 1, 2025.
