PSO to rebuild about 23 miles of 69-kV line

Public Service Company of Oklahoma (PSO), a unit of American Electric Power (NYSE:AEP), on Sept. 26 said that it plans this fall to rebuild about 23 miles of 69-kV transmission line between Hugo and Valliant.

The need to upgrade the line was determined by the Southwest Power Pool, PSO said, adding that the upgrades will strengthen the local electric transmission system, as well as provide support for future growth and economic development.

The company said that the components of the Hugo-Fort Towson-Valliant Transmission Line Rebuild Project include:

  • Replacing wood poles with steel, single-pole structures and new wires
  • Upgrading equipment at three substations
  • Work that will take place within company owned easements

According to a project fact sheet, the estimated investment on the project is $27m.

The line rebuild begins at the Hugo substation, located near North A Street in Hugo, to the Fort Towson substation, located northeast of Fort Towson, then continues east to the existing Valliant substation, the fact sheet noted.

An approximately six-mile section of the line around Hugo Lake is already equipped with updated transmission facilities and will not need to be rebuilt as part of the project, according to the fact sheet.

The typical height of the structures will be about 70 feet, and the typical right of way width will be about 100 feet, the fact sheet noted.

PSO said in its statement that construction at the Valliant substation is expected to begin this fall, while construction at the Fort Towson and Hugo substations will begin in early 2018, along with the construction to rebuild the transmission line. The line will be built in phases and is expected to be complete by late 2018, the company said.
