Entergy’s (NYSE:ETR) Entergy Arkansas, Inc., (EAI), on Feb. 21 told the Arkansas Public Service Commission that project construction and final testing of a new 115-kV switching station, which consists of two 115-kV transmission line segments and a 115-kV, 3-breaker ring bus arrangement and other associated facilities, have been completed, with substantially all final costs received as of January.
The transmission outage for the project, located in Arkansas County, Ark., has concluded and the transmission facilities were energized on Oct. 6, 2017. The company also said that the project’s total final cost was about $4.96m, and that all of the costs for the electrical facilities are the responsibility of Stuttgart Solar LLC.
As noted in a May 2016 order granting EAI a certificate of public convenience and necessity (CCN) to build and operate the switching station, EAI filed its application for a CCN in January 2016. The project was proposed to provide a generation access point to an 81-MW solar photovoltaic generation facility being built by Stuttgart Solar in Arkansas County.
The May 2016 order was signed by an administrative law judge (ALJ). The commission, in an August 2016 order, directed its secretary to close the docket as following the ALJ’s order, there was “no further action to be taken in this matter at” that time.
As noted in the May 2016 order, Stuttgart Solar was building its 81-MW facility adjacent to the Stuttgart Ricuskey to Gillett 115-kV Transmission Line on a 500-acre tract of land about seven miles southeast of Stuttgart. EAI and the Midcontinent ISO (MISO) negotiated a generator interconnection agreement (GIA) with Stuttgart Solar and EAI, which was filed with FERC in September 2015. The May 2016 order also noted that the switching station was included in the MISO Transmission Expansion Planning Process. Among other things, the order noted that in order to provide a connection for the solar facility to the transmission grid, it is necessary to build the switching station.
