Recommended order calls for approval of line, switching station, substation in Mississippi

A June 22 recommended order signed by a Mississippi Public Service Commission hearing examiner calls for the approval of a 115-kV electric transmission line and switching station, as well as of a 115:13.2-kV substation facility, all in Pike County, Miss.

As noted in the recommended order, Cooperative Energy and Magnolia Electric Power Association (MEP) in late January filed a joint petition for a certificate of public convenience and necessity authorizing Cooperative Energy to build, maintain, and operate the 115-kV line and switching station, and for MEP to build, maintain, and operate the 115:13.2-kV substation.

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

The hearing examiner said that in order for Cooperative Energy and MEP to improve reliability and quality of power, as well as to enable them to maintain adequate voltage levels and increased demand capabilities on MEP’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 Cooperative Energy and MEP acquire the necessary sites and rights of way (ROWs), through appropriate means, including, if necessary, eminent domain, and to build, own, operate, and maintain the line, switching station, and substation facilities.

Discussing the facilities, the hearing examiner said:

  • Cooperative Energy line (Holmesville 115-kV Tap) – About 1.9 miles of 115-kV transmission line would be required between Cooperative Energy’s proposed 115-kV Holmesville switching station and MEP’s proposed 115:13.2-kv Holmesville substation. The proposed line begins in the Northeast 1/4 of the Southeast 1/4 of Section 14, Township 3 North, Range 9 East in Pike County at Cooperative Energy’s proposed Holmesville switching station, then runs generally southeast about 1.9 miles to MEP’s proposed Holmesville substation in the Southwest 1/4 of the Southeast 1/4, the Southeast 1/4 of the Southeast 1/4, and the Northeast 1/4 of the Southeast 1/4 of Section 22, Township 3 North, Range 9 East in Pike County. The estimated cost of the line is $845,000
  • Cooperative Energy Holmesville switching station – To accommodate MEP’s proposed 115:13.2-kV Holmesville substation, it is necessary for Cooperative Energy to build the 115-kV switching station with four line terminations. The station would be built using a lattice steel structure and have three motor-operated, remotely controlled 115-kV switches. The proposed switching station would be located at a point on the west side of Matthews Road and adjacent to EMI’s existing 115-kV transmission line in the Northeast 1/4 of the Southeast 1/4 of Section 14, Township 3 North, Range 9 East in Pike County. The estimated cost of the switching station is about $500,000
  • MEP Holmesville 115:13.2-kV substation – The substation, which would be designed to utilize two 12/16/20 MVA transformers, would be a lattice steel structure with aluminum tube bus on the high-side and aluminum angle bus on the low-side. The proposed substation would be built on an approximately nine-acre site, which is located on the west side of Matthews Road in the Southwest 1/4 of the Southeast 1/4, the Southeast 1/4 of the Southeast 1/4, and the Northeast 1/4 of the Southeast 1/4 of Section 22, Township 3 North, Range 9 East, in Pike County. The estimated cost of the substation is $1.9m

Among other things, the hearing examiner said that exceptions to the recommended order may be filed with the commission within 15 days from the date that the order is issued. If exceptions are not timely filed, then the recommended order is to become the commission’s order, the hearing examiner said.
