Transmission Upgrades

161 kV Line Project

 

In 2020, the Liberty Electric Operations team rebuilt an aging transmission line stretching for 42-miles from Neosho, Missouri to Flint Creek Arkansas. 

Aged, wooden structures were replaced with new and improved steel structures and fiber was added to the line in order to provide real-time information to Liberty crews. The replacement of aging poles will help the transmission line better withstand storms and the addition of fiber will help Liberty crews locate potential faults more qucikly during an outage. 

Project Goals:

  • Reduce number of outages
  • Reduce outage duration
  • Improve overall service reliability for electric customers

161 kV Project Facts:

  • Replaced 280 wood structures with new, steel structures
  • New fiber OPGW was installed to help speed the outage restoration process
  • This transmission line feeds the southern part of Liberty's electric system
  • Began in summer 2020 and completed in winter 2021

4kV to 12kV Conversion Project 

 

Beginning in 2021, the Liberty Electric Operations team began the 4kV to 12kV conversion project in downtown Joplin, Missouri. This project started from 8th to 15th St. and continued about 16 blocks from Missouri St. to Porter St. During this project, hundreds of aged poles and transformers were replaced and two new substations were constructed. 

Aged, wooden structures from the 1940s - 1960s were replaced with new and improved steel structures and fiber was added to the line in order to provide real-time information to Liberty crews. The replacement of aging poles will help the transmission line better withstand storms and the addition of fiber will help Liberty crews locate potential faults more qucikly during an outage. 

Project Goals:

  • Reduce number of outages
  • Reduce outage duration
  • Improve overall service reliability for electric customers

4kV to 12kV Conversion Project Facts:

  • Replaced 139 wood poles with new, steel structures
  • Replaced 418 wooden crossarms
  • Replaced 562 transformers
  • Two new substations constructed 
  • Project is still currently ongoing (updated Jan 20, 2022)
