Mississippi hearing examiner recommends approval of line, switching station, substation

A Mississippi Public Service Commission hearing examiner, in a Feb. 20 order, recommended approval of an electric transmission line, switching station and substation.

As noted in the recommended order, Cooperative Energy and Southwest Mississippi Electric Power Association (SWEPA) – collectively referred to as the petitioners – last September filed with the commission a joint petition for a certificate of public convenience and necessity authorizing the petitioners to acquire the necessary sites and rights of way (ROWs) for Cooperative Energy to build, maintain, and operate a 115-kV electric transmission line and switching station in Adams County, Miss., and for SWEPA to build, maintain, and operate a 115:12.47-kV substation facility in Adams County, together with all necessary switches, buses, as well as related equipment and facilities.

No objections or protests to the granting of a certificate to the petitioners have been filed; no protestants appeared at the hearing on said cause; and no objections have been made to the granting and issuance of the order. As the matter is uncontested, a hearing is not required, the hearing examiner added.

In order for the petitioners to improve reliability and quality of power in certain areas, and to enable them to maintain adequate voltage levels as well as increased demand capabilities on SWEPA’s entire electric distribution system so that it may be able to render an adequate and reliable supply of energy to all of its members, it is necessary that the petitioners acquire the necessary sites and ROWs, through appropriate means, including, if necessary, eminent domain, and to build, own, operate, and maintain the electric transmission line, switching station, and substation facilities, the hearing examiner said.

The facilities for which the petitioners seek a certificate were described in the recommended order as such:

  • Cooperative Energy Cloverdale 115-kV switching station with four line terminations at an estimated cost of $500,000. The proposed switching station will be located at a point adjacent to EMI’s existing 115-kV transmission line west of Lower Woodville Road and north of St. Catherine’s Creek in Section 7, Township 6 North, Range 3 West, Adams County. The switching station would be a lattice steel structure and have three motor-operated, remotely controlled 115-kV switches
  • Cooperative Energy Cloverdale 115-kV Tap, which would entail about 0.4 miles of 115-kV transmission line that would be required between the proposed Cooperative Energy’s Cloverdale 115-kV switching station and SWEPA’s proposed Cloverdale substation. The estimated cost of the 115-kV transmission line is $300,000
  • SWEPA Cloverdale substation, which would be a 115:12.47-kV substation designed to utilize two power transformers; initially, one 15/20/25 MVA transformer would be installed. The proposed substation would be built on an approximately 2.9-acre site, which is located on the west side of Lower Woodville Road about 0.2 miles south of St. Catherine’s Creek in the east side of Section 10 and west side of Section 7, Township 6 North, Range 3 West, Adams County. The estimated cost of the Cloverdale substation is $1.75m

It is anticipated that construction would begin within four months from the date of granting a certificate by the commission, the hearing examiner added.

The purpose of the transmission line, switching station, and substation facilities is to provide sufficient capacity, as well as improve reliability and quality of service in the Cloverdale and Lower Woodville Road areas of Adams County, the hearing examiner said. That are, which includes the Natchez Adams County Port Industrial Park, is projected to see an increase in growth, the hearing examiner noted.

Petitioners aver that the line, switching station, and substation facilities are required in order for SWEPA to have the required supply of power to serve the present and immediately foreseeable requirements of its members within its certificated area in Adams County and for Cooperative Energy to provide a reliable source of power from its transmission system to the new SWEPA delivery point, the hearing examiner said.

The commission determines and finds that public convenience and necessity require and will require the awarding of the certificate and orders that a certificate be granted to the petitioners to acquire the necessary sites and ROWs; for Cooperative Energy to build, maintain, and operate the 115-kV line and switching station; and for SWEPA to build, maintain, and operate the 115:12.47-kV substation facility.

The hearing examiner also said that exceptions to the recommended order may be filed with the commission within a period of 15 days from the date of issuance of the recommended order. If exceptions are not timely filed, the recommended order is to then become the commission’s order, the hearing examiner said.
