Entergy Arkansas seeks approval for pair of 115-kV transmission lines

Entergy Arkansas Inc. (EAI) applied Sept. 19 at the Arkansas Public Service Commission for a Certificate of Public Convenience and Necessity allowing it to construct, operate, and maintain two new 115-kV transmission line segments and related transmission facilities located in Saline County, Arkansas.

The proposed facilities consist of two slack-span line segments approximately 150 feet each (0.06 miles total) of a new single circuit transmission line to provide a 115-kV connection to a new distribution substation being constructed by Benton Utilities for the City of Benton, Arkansas.

These facilities will be constructed on property owned by the City of Benton, including the majority of the right-of-way (ROW) for the transmission cut-in to the Hurricane Lake Substation, and on EAI existing transmission line ROW. The City of Benton owns the approximate four-acre site and will provide EAI ROW on which the facilities would be constructed except for a small property gap located between the Hurricane Lake Substation site and the existing 115 kV transmission ROW (0.02 acres). EAI has secured an easement for this small parcel from the landowner, which landowner was one of the initial landowners that sold the property to the City of Benton for the Hurricane Lake Substation. This site is adjacent to the EAI Mabelvale EHV Substation to EAI River Ridge Switching Station 115 kV Transmission Line and includes the Hurricane Lake Substation footprint.

The route for the proposed facilities was based on the location selected for the Hurricane Lake Substation site. The ROW easement needed for the new facilities will be furnished by EAI and the City of Benton, whose Hurricane Lake Substation site consists of approximately four acres located in Saline County, Arkansas, along the north side of the existing EAI Mabelvale EHV Substation to EAI River Ridge Switching Station 115 kV Transmission Line. The site is also located on property between Severn Landing Road and Wedgewood Drive, north of US Interstate 30 and northeast of the City of Benton.

The proposed route is a direct route from the EAI Mabelvale EHV Substation to EAI River Ridge Switching Station 115 kV Transmission Line.

Benton Utilities requested EAI provide a new 115 kV source connection to its new proposed 115/13.8 kV distribution substation, the Hurricane Lake Substation. The tap lines to connect the Hurricane Lake Substation would be these new facilities, which include an in-and-out transmission service installation from the existing EAI Mabelvale EHV Substation to EAI River Ridge Switching Station 115 kV Transmission Line, EAI Line No. 966.

EAI is providing the 115 kV connection to the City of Benton consistent with the company’s wholesale service standard with municipalities subject to the EAI Local Balancing Authority Agreement (LBA) dated Dec. 8, 2014.

The in-service date for the Hurricane Lake Substation is projected to be May 30, 2017, and construction of these proposed facilities by EAI would commence as soon as possible following commission approval.
