Arkansas Transmission Improvement and Expansion

As of 8/29/18. Subject to change. Maps are for illustrative purposes only.

Happy Valley to Hot Springs EHV Transmission Project

Entergy Arkansas continually evaluates its resource needs to ensure it can provide reliable and reasonably priced electric service to electricity consumers in Arkansas and that includes the evaluation of the needs and drivers of the Happy Valley Transmission Project. Entergy Arkansas, by using its most recent reliability evaluation, factoring in the latest forecast of electrical consumption and other factors, has determined that the transmission project is no longer required at this time to address North American Electric Corporation Reliability Transmission Planning Performance Requirements. Consequently, Entergy Arkansas is discontinuing its efforts to identify potential routes for this project.

Entergy Arkansas will continue to monitor and evaluate its network and will determine projects that will be required in the future to ensure that it is able to continue to provide reliable and reasonably priced electric service to its customers, while also complying with the NERC Transmission Planning Performance Requirements.

If you have any questions about the project, please feel free to contact Bill Newton at bnewton@pinnacleenergyservicesinc.com or (479) 719-4346.


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 approximately 26 mile line from Lake Village Bagby to Reed, and the construction of a new approximately22 mile line from Reed to Monticello East. The projects also include the construction of a new breaker switching substation at Reed.

Cost: Approximately $81 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 went into service in February 2017. Reed to Monticello East  is expected to be placed in service by fall of 2018.

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


Jonesboro EHV

Description: This project is located in northeast Arkansas and will consist of tapping the existing Independence to Dell 500 kV line near the existing Hergett 161 kV station and building a new Power Line Road switching station, including a 500/161 kV autotransformer. Power Line Road to Trumann (4.9 miles), Trumann - Trumann West (6.5 miles), and Jonesboro to Jonesboro SPA (0.9 miles) 161 kV lines will all be upgraded.

Cost: Approximately $79 million.

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

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 summer 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.

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

COMPLETED


Mabelvale: Replace 500-115 kV Autotransformers

Description: This project is located in central Arkansas and will consist of replacing the existing 500-115 kV autotransformers at Mabelvale with larger capacity autotransformers.

Cost: Approximately $21 million.

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

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

 

Independence: Replace 500-161 kV Autotransformers

Description: This project is located in northeast Arkansas and will consist of replacing the existing 500-161 kV autotransformers at Independence with larger capacity autotransformers.

Cost: Approximately $23 million.

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

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