Planned construction to improve reliability in Cooper Landing

Cooper Landing residents can expect to see significant construction activity soon as Chugach is rebuilding part of the distribution line that feeds into the community. The Daves Creek Feeder 352 originates out of the Daves Creek Substation, between milepost markers 40 and 41 of the Sterling Highway, terminating at the Russian River ferry crossing.

This project will reconstruct approximately four miles of the line from the substation to Kenai Lake. It will increase capacity and reliability by adding poles and replacing conductors and cross arms on the feeder. The construction has been awarded to Alaska Line Builders and will begin after freeze-up. The construction will be done with the line energized, minimizing disruptions to members. Construction is scheduled to be complete by the end of the year.

Chugach has other projects scheduled for the Cooper Landing/Moose Pass area. A public meeting discussing the details of these projects is scheduled for the Cooper Landing Community Club on Nov. 4, from 6 to 7:30 p.m.

Busy schedule for Chugach construction projects

Chugach has several projects scheduled to improve reliability for our members. Below is a short list of projects underway or coming up:

Old Seward Hwy. undergrounding

Work is underway undergrounding overhead conductors between Huffman and O’Malley. Construction is expected to be complete in the fall.

Arctic Road undergrounding

This project will underground the distribution lines along Arctic Road between Raspberry and Dimond. This Title 21undergrounding project is scheduled for construction in the fall.

Substation 3 – Downtown

Substation 3 is a new distribution substation located in Downtown Anchorage. This new substation will allow Substation 9/9a, adjacent to the Coastal Trail off 2nd Avenue, to be retired. Commercial operation is expected later in 2021.

Cooper Landing feeder reconstruction

This project will reconstruct approximately four miles of line between the Daves Creek and Kenai Lake substations. Designed to improve reliability to members in Cooper Landing, construction is scheduled for later in 2021.

Quartz Creek transmission line

There are two sections of line Chugach is working to rebuild for this project. The Summit Lake to Daves Creek section is tentatively scheduled to begin in Jan. 2023. The Indian to Girdwood section is tentatively scheduled for 2023/2024 construction.

Old Seward Hwy - O’Malley to Huffman overhead to underground conversion

A project undergrounding about one mile of distribution and sub-transmission lines along the Old Seward Highway is underway this summer. The project, from O’Malley to Huffman, is part of the undergrounding requirements of Anchorage’s Title 21. Mobilization started in April, and the project is expected to be completed in the fall. Crews will come back in the spring of 2022 for landscaping.

Muldoon overhead to underground conversion

This project will underground approximately one mile of primary overhead distribution line on the West side of Muldoon from Island Drive to Northern Lights Blvd.  It is an overhead to underground conversion and will be funded through collection of Title 21 undergrounding fees.

The design has been completed and permits have been received.  NPC was provided a notice to proceed and started construction in July.  Staking has been completed; trenching and conduit installation has started.  The project will be substantially completed by the end of the year and landscaping will be finished in 2021.
