Avista Corp.
Under the transaction, Avista transferred certain equipment to BPA as consideration for the purchase of 15 miles of 115-kV transmission assets in the Airway Heights, Wash.
The assets provide transmission interconnection and load service to two BPA wholesale utility customers. However, the assets are physically and electrically separate from BPA's main transmission network and are entirely surrounded by Avista's transmission system.
"The Transaction is necessary to enable both parties to better comply with mandatory reliability standards governing maintenance of bulk electric system equipment," Avista noted in its Aug. 31 application. (FERC docket EC18-147)
