Beacon Light Substation

Project Need

In order to site future facilities ahead of growth in the Eagle area, Idaho Power has determined at least one new substation will be required west of Eagle.

To continue to provide reliable electric service and to meet both existing and future electrical capacity needs for the area, Idaho Power constructed a new substation on the southeast corner of Beacon Light and Linder roads. The project also will require a sub-transmission line along Beacon Light Road in the future.

Substation Details

When energized, Beacon Light Substation will serve the surrounding area north and west of Eagle. The substation will transform electricity from 138,000 volts (138 kV) to 12,470 volts (12.47 kV), and will be designed to ultimately serve up to eight 12.47-kV distribution circuits to bring electricity from the substation to homes and businesses in the area.

Sub-Transmission Line Details

The sub-transmission line will be designed for two 138-kV sub-transmission circuits at the top and two 12.47-kV distribution circuits built underneath. The line will use steel poles and is proposed to run north along the east side of Idaho 44-16 from State Street (Idaho 44) to Beacon Light Road. A printable map is available. Road right of way or private easements will be used for the line corridor.

  • Structure type: Tubular steel poles
  • Structure heights: 75 feet to 85 feet
  • Structure spacing: 300 foot average
