Entergy’s (NYSE:ETR) Entergy Arkansas Inc., (EAI) on Nov. 22 filed an application with the Arkansas Public Service Commission (APSC) for a certificate of public convenience and necessity (CCN) in relation to its proposal to build and operate a new four-breaker ring bus designed switching station in Jackson County, Ark., to be built near the existing EAI Newport Industrial 161-kV substation (the Mallory switching station).
As part of the effort, EAI is also proposing to terminate the existing EAI Newport to Walnut Ridge 161-kV and the EAI Newport to Jonesboro 161-kV transmission lines into the Mallory switching station. Terminating the existing EIA Newport to Walnut Ridge line into the switching station would require the construction of two new, approximately 1.2-mile, 161-kV transmission lines, EAI added.
In addition, but not part of this request for a CCN, the company said that it would rebuild the first approximately four miles of the existing EAI Newport to Walnut Ridge line for reliability and load flow purposes.
The proposed electrical facilities are needed to eliminate potential voltage flicker issues around the Newport area, which has an industrial load, Arkansas Steel Associates, with an alternating current arc furnace, the company said.
Construction, if the project is approved, is scheduled to begin in 3Q17, the company said, adding that completion of the proposed electrical facilities is projected for 4Q18.
The total estimated cost of the proposed electrical facilities is $15.2m, the company said.
