Carroll Electric Cooperative Corporation (CECC), in a recently filed application with the Arkansas Public Service Commission, requested that the commission issue a certificate of public convenience and necessity allowing CECC to build, operate, and maintain certain transmission and substation facilities in Benton County, Ark.
One of the new transmission lines would begin at a point on the Centerton-Highfill transmission line in Section 28, Township 19 North, Range 31 West, Benton County, and end at the proposed Morning Star substation in Section 35, Township 19 North, Range 31 West, Benton County. CECC added that the other new line would begin at the proposed Morning Star substation and end at the NACA substation in Section 16, Township 18 North, Range 31 West, Benton County.
Noting that its loads and service reliability requirements continue to grow rapidly in the I 49 corridor area of Benton County, CECC said that to provide for those needs, CECC needs to build to build the two new transmission lines and the new substation. While the new lines would initially be operated at 69 kV, they would be built for future operation at 161 kV, CECC said, adding that the higher operating voltage is anticipated to be required in the future as electric loads continue to grow.
The Morning Star Line would be about 2.9 miles long, while the NACA Line would be about 5.2 miles long. CECC also said that the portion of the Morning Star Line from Mill Dam Road to the Morning Star substation would be built with a distribution underbuild. The portion of the NACA Line from the Morning Star substation to about Philpott Road would be built with double circuit distribution underbuild. Both lines would require new easements 100’ in width, CECC added, noting that it already owns the property on which the Morning Star substation would be built.
The total estimated cost of the project is about $6.5m – that is, about $1.8m for the Morning Star Line, about $2.8m for the NACA Line, and about $1.9m for the Morning Star substation, CECC said.
