Southwestern Electric Power Company (SWEPCO), in a Sept. 19 application filed with the Arkansas Public Service Commission (APSC), said that it proposes to build a new switching station to be located adjacent to Arkansas Electric Cooperative Corporation’s (AECC) existing East Fayetteville station.
The new facilities will include a three-breaker switching station configuration with two station box bays to serve AECC with two 161-kV transmission feeds, the company said. Additionally, there will be minor adjustments to SWEPCO’s existing 161-kV transmission lines to interconnect them to the proposed East Fayetteville switching station, the company said, noting that all adjustments will take place within either existing right of way (ROW) or on property that SWEPCO is presently negotiating to purchase from AECC.
All of the proposed facilities are located in Washington County, Ark., the company said.
Discussing the need for the proposed facilities, SWEPCO said that its existing Dyess to Hyland 161-kV transmission line serves AECC’s East Fayetteville station. AECC has approached SWEPCO’s parent company, American Electric Power (NYSE:AEP), and has indicated that AECC needs to expand its existing East Fayetteville station to facilitate conversion of a portion of AECC and Ozark Electric Cooperative Corporation’s 69-kV system to a 161-kV system. SWEPCO added that its existing interconnection facilities must be relocated and modified slightly to allow AECC’s expansion.
The proposed facilities will allow the operation and ownership to remain clear between the two utilities while still providing the necessary interconnection, SWEPCO said.
The total estimated cost to build the proposed East Fayetteville switching station and associated facilities is about $7.2m, SWEPCO said. The cost of the facilities will be paid with internally generated cash and then on a long-term basis will be included in SWEPCO’s overall financing plans, the company said.
