An example of how
an Idaho Power substation appears in an urban setting. |
Project Need
According to U.S. Census
figures, Canyon County was one of the fastest growing areas in the nation
with a population jump of more than 15 percent between 2000 and 2003.
During that same period, Idaho Power connected on average more than
2,700 new customers per year in the Canyon County area. This growth has
substantially increased Idaho Power’s electrical
load and is straining existing electric facilities.
To meet the power needs of some of this growth, Idaho Power plans to construct the Cherry Substation and associated 138,000-volt (138-kV) sub-transmission line. These facilities, planned to be in service in September 2009, will allow Idaho Power to continue providing reliable electric service to meet both existing and future electrical capacity needs for northeast Nampa.
Cherry Substation Details
The proposed Cherry Substation will be located on the southeast
corner of Cherry Lane and Can-Ada Road. The substation will sit back off the
road surrounded by a slatted chain link fence and landscaping. Click for a printable map (PDF, 437KB).
The substation is used to transform electricity from 138kV to 12.5kV. Initially, three 12.5-kV distribution circuits will bring electricity from the substation to homes and businesses in the area. As the northeast Nampa area continues to grow, up to five additional 12.5-kV distribution circuits could be installed.
Sub-Transmission Line Details
The exisiting 69-kV sub-transmission line portion, which runs through the golf course and then along the north side of Franklin Road, will be converted to 138kV. We will tap this line at the corner of Franklin Road and Can-Ada Road and construct a new 138-kV line which will run north along Can-Ada about one mile to Cherry Substation.
Most of the poles will be designed with the 138-kV sub-transmission circuit in the top position, and a 12.5-kV distribution circuit in the lower position. Road right of way or private easements will be used for the line corridor.
