Comments due April 24 on TVA’s proposed 161-kV transmission system upgrades

The Tennessee Valley Authority (TVA) on March 13 said that it is seeking public input regarding its proposal to build two to three miles of transmission line in the Longino area of Philadelphia, Miss., and four to five miles of transmission line in the Sandtown area of Philadelphia, in order to serve new and expanded Central Electric Power Association (CEPA) substations.

The lines would be built on steel pole structures on a 100-foot-wide right of way (ROW), TVA said.

In total, the upgrades to TVA’s transmission system will have a cost of about $6m, TVA said.

According to TVA, in Longino, the proposed line would begin at TVA’s Noxapater SW-North Philadelphia 161-kV Transmission Line and run east to CEPA’s expanded Longino substation near the intersection of Country Road 608 and Highway 15.

“The Longino substation has been in service for many years operating at a delivery voltage from TVA at 46kV,” CEPA General Manager Paul Long said in a separate March 13 TVA posting. “TVA and CEPA have both agreed the need to upgrade the delivery voltage to 161kV. This upgrade will increase the reliability and service to all the customers in the Fork Road, River Road, Arlington, Burnside, Stallo, Longino, Hwy.21 N. and other areas.”

In Sandtown, the proposed line would begin at TVA’s Midway-Philadelphia Transmission Line and run northwest to CEPA’s new Sandtown substation near Country Road 753.

TVA said that the Sandtown substation – which will act as a backup to the Longino, Bloomo, and Philadelphia substations – will increase the reliability and service in the Sandtown and Bogue Chitto areas, as well as in the eastern area of Neshoba County.

TVA also noted that for Longino, there are three tap points and 14 alternative transmission line segments under consideration, while for Sandtown, there are three tap points and 13 alternative transmission line segments under consideration.

According to the project schedule, the preferred route for field surveys will be determined this spring, and surveys of the ROW are scheduled to begin in the fall. Easement purchases for the Longino project are scheduled to begin in spring 2018, and in summer 2018 for the Sandtown project, according to the schedule.

Construction is scheduled to begin in winter 2019/2020 for the Longino project, and in winter 2020/2021 for the Sandtown project, TVA said. The scheduled completion date for the Longino project is March 2020, and March 2021 for the Sandtown project, TVA said.

An open house will be held on March 23 in Philadelphia, and the public may also submit comments by phone at 800-362-4355; by email at newtransline@tva.gov; or by mail to Cherie Minghini or Todd Moore, Tennessee Valley Authority, 1101 Market St., MR 4G, Chattanooga, TN, 37402-2801. TVA added that the deadline to submit comments is April 24.
