Project Need

According to U.S. Census figures, Canyon County was one of the fastest growing areas in the nation. In order to serve the growing electrical needs of this area, Idaho Power is projecting that a new electrical distribution substation will be required in the southwest Nampa area by 2016. The proposed substation would be served by a new 138,000-volt (138-kV) sub-transmission line.

Substation Details

The proposed substation site is between Lewis Lane and Lake Shore Drive, approximately 1,500 feet west of 12th Avenue Road. The 1.5 acre site is approximately 260 feet’ by 250 feet. The station will be gravel surfaced and enclosed by a seven-foot-tall chain link fence with privacy slats. Landscaping will be installed around the station perimeter.

Upon obtaining a Conditional Use Permit from Canyon County, Idaho Power will erect a sign indicating that the property is a permitted electrical substation site with an anticipated construction date in 2016.

Sub-Transmission Line Details

The proposed substation would be served by a new 138,000-volt (138-kV) sub-transmission line to be constructed from an existing sub-transmission 1,500 feet west of the proposed project. The line serving the new Lake Shore Substation will use single pole construction averaging 80 feet in height with spans averaging 300 feet. The construction date of this line will coincide with the need date for a substation, currently planned for the year 2016.
