Arkansas Transmission Improvement and Expansion

As of 2/3/17. Subject to change. Maps are for illustrative purposes only.

Southeast Arkansas Reliability Projects

Description: Three projects located in southeast Arkansas are involved in the construction of a new 230 kV transmission line (initially to be operated at 115 kV). Included in these projects are the construction of a new line approximately of 26 miles from Lake Village Bagby to Reed, and the construction of a new line approximately of 22 miles from Reed to Monticello East. The projects also include the construction of a new breaker switching substation at Reed.

Cost: Approximately $78 million.

Status: These projects are expected to be in service as follows: Lake Village Bagby to Macon Lake went into service in May 2014. Macon Lake to Reed (summer 2017) and Reed to Monticello East (summer 2018).

Benefits: This project addresses future load growth and reliability needs in the southeastern portion of Arkansas.

White Bluff Area Improvements

Description: These projects in the Pine Bluff area of central Arkansas include the reconfiguration of the White Bluff 500 kV substation, the addition of a new 500-230 kV autotransformer, and the construction of a new 23 mile-230 kV transmission line from Entergy Arkansasí White Bluff generating facility to Woodward Substation.

Cost: Approximately $69 million.

Status: The project was placed into service in July 2016.

Benefits: This portfolio of projects addresses future load growth and reliability needs in the White Bluff/Woodward areas of central Arkansas.

COMPLETED


Osceola Area: Construct New 500/230 kV Substation

Description: This project, located in northeast Arkansas, involves cutting in a new Driver 500 kV substation on the existing San Souci - Shelby 500 kV line.  Driver substation will be constructed with two 500/230 kV autotransformers serving the new Driver 230 kV station.

Cost: Approximately $67 million.

Status: This project was placed into service in April 2016.

Benefits: This project addresses future load growth and reliability needs in northeast Arkansas.

Pine South to Hot Springs Milton by completing an additional loop in the Hot Springs area.

Cost: Approximately $35 million.

Status: Project placed into service in April 2016.

Benefits: This project addresses future load growth and reliability needs in the southwest Hot Springs area.

COMPLETED


Jim Hill Area Upgrades

Description: This project is located in northeast Arkansas and will consist of rebuilding the existing 39.3 mile Jim Hill to Datto 115 kV line and converting the line and all stations to 161 kV operation.

Cost: Approximately $64 million.

Status: Scoping and Design Phase.  This project is expected to be placed in service by spring of 2019.

Benefits: This project addresses future load growth and reliability needs in the northeastern portion of Arkansas.


AECC Hydro Station #2 to Gillett: Construct New 115 kV Line

Description: This project, located in east-central Arkansas, involves the construction of a new 15.6mi 115 kV transmission line connecting Entergy Arkansas' Gillett 115 kV Substation with AECC's Hydro Station #2.

Cost: Approximately $24 million.

Status: The project was placed into service in July 2016.  

Benefits: This project addresses future load growth and reliability needs in the east-central area of Arkansas.
