Pinehurst Underground Cable Replacement

City Light Undergrounding Project

Project Description

We began planning a series of replacement projects for the Pinehurst area in 2024 starting with the need to test primary cables to determine overall system health. The testing project will help us anticipate the overall replacement needs of the Pinehurst area.

Location

Construction will occur in the Pinehurst neighborhood.

What's Happening Now?

Project Update (November 2025): We are testing our underground equipment soon. This will help us identify future replacement needs. Please view the schedule below for more information.

Community Benefits

This work will result in enhanced electrical reliability and reduce the likelihood of unplanned power outages in the Pinehurst area.

Anticpated Testing Impacts

  • Crews will briefly open electrical vaults to test underground cables.
  • They’re testing equipment in approximately 55 vaults on five different streets.
  • Planned power outages are not needed for this work.

During testing, you can expect:

  • Limited parking and sidewalk access within the work zone.
  • Construction signs and flaggers redirecting pedestrian and vehicle traffic where needed to maintain safety.
  • Some equipment noise.

Testing Schedule

December 2 - 10, 2025
Work hours: Monday - Friday,
9 a.m. - 3 p.m.

The schedule for future replacements will be determined by the results of the testing. We currently anticipate the following replacement timelines:

  • Testing Cables - December 2025
  • Receive Report, Determine Replacements, Request Permits - January - March 2026
  • Planned Outage Coordination - March - May 2026
  • Equipment and Cable Replacement - May - July 2026
  • Project Closeout - August 2026

If testing reveals unanticipated results, we may need to expand the scope of the necessary work which could lengthen the schedule.
