C&L Electric Cooperative Corporation on Sept. 7 filed an application with the Arkansas Public Service Commission (APSC), requesting a certificate of public convenience and necessity to build, operate, and maintain a 115-kV transmission line in support of the new Hermitage substation, to be located adjacent to the existing Hermitage meter point.
C&L said that the purpose of the transmission line and substation is to eliminate the need for the Hermitage meter point and to improve system reliability in the area.
The proposed approximately two-mile line would be built with 477 MCM 26/7 ACSR conductor with an overhead optical ground wire, C&L said, adding that a 220-foot right of way (ROW) easement is required from the Hermitage South switching station extending east about 0.25 miles to accommodate two 115-kV lines operated by Entergy (NYSE:ETR), as well as the 115-kV line to be operated by C&L. A 100-foot ROW easement is required for the remainder of the line, C&L said, noting that the typical pole would be an 80-foot steel pole.
According to the Sept. 7 testimony on behalf of C&L of Adam Toth, vice president of Toth & Associates, Inc., the designed route for the 115-kV line would originate in the Hermitage South switching station, owned by AECC, and then travel southeast along Arkansas 160 and Bradley Road 54 to the new Hermitage substation. No significant technical or engineering issues are expected other than the typical engineering requirements of designing substation and transmission lines to meet safety standards, Toth said.
Construction is anticipated to begin in October 2018, with project completion expected by Dec. 31, 2018, Toth noted.
The estimated cost of the 115-kV line is $1m, while the estimated cost of the Hermitage substation is $2m, C&L said in its application.
C&L noted that it would finance the construction from its general fund, and would apply for a loan from the Rural Utilities Service – which initially approved the projects as part of C&L’s 2014-2017 Construction Work Plan – in a sum equal to the costs of the construction. C&L said that its general fund would then be reimbursed by the loan proceeds.
The construction, C&L said, “is in the public interest, convenience and necessity in that it is required to provide adequate service for area consumers.”
