On March 1, 2005, the Anchorage Assembly adopted certain revisions to Section 21.07.050, Utility Distribution Facilities, of the Anchorage Municipal Code. These revisions require an electric utility to “include as part of its annual capital improvement plan, a five-year undergrounding program” (21.07.050F1). In each of the years of this program the electric utility shall plan on expending “at least two percent of a three-year average of its annual gross retail revenues derived from utility service connections within the municipality” (21.07.050G1a). In accordance with this requirement, Chugach Electric Association (Chugach) targets approximately $6.6 million annually to underground existing overhead facilities. Over-expenditures or under expenditures may be carried over as an adjustment to the following year’s obligation.
When developing the five-year undergrounding program, the electric utility can choose which existing lines to underground. Specifically, priorities of the program “shall be based on undergrounding in conjunction with the electric utility’s essential system improvements and then by target area” (21.07.050F1).
This document contains Chugach’s anticipated five-year undergrounding plan, comprising 34 projects with a total estimated capital cost of $54,495,000 to be expended on undergrounding of non-conforming overhead lines between 2021 to 2025. The inclusion of a project within this plan does not guarantee that the project will be constructed in the designated year. Every effort is made to complete the projects according to the schedule in Part IV, but circumstances may cause a project to be completed earlier or later than planned.
The projects were chosen to best serve Chugach's overall system needs and with consideration of the designated target areas.
