Transmission Lines

Evergy Presents Design Options to Rebuild Transmission Line

Evergy to rebuild transmission line along Mossman and Green streets using smaller wood or steel poles, move the poles closer to the street wherever possible.

Evergy Kansas Central Inc. (formerly Westar Energy) will be rebuilding the transmission line along Mossman and Green streets, using smaller wood or steel poles. The utility will also be also moving the poles closer to the street wherever possible.

On Dec. 3, Evergy hosted an open house to present design options that meet these goals to residents in the area for feedback. The feedback received will be incorporated and reviewed to finalize the design. Construction is tentatively scheduled to be completed by the end of 2020.

Option A

  • Wood poles, where possible, with an average height of 79 ft versus the existing height of 90 ft.
  • Wood poles, where possible, to be on average 10 to 15 ft closer to the roadway.
  • Steel turning structures will remain in place. Top sections of the structures will be replaced with shorter sections, reducing the overall height by 10 to 12 ft.

Option B

  • Wood poles, where possible, with an average height of 79 ft versus the existing height of 90 ft.
  • Wood poles, where possible, to be on average 10 to 15 ft closer to the roadway.
  • Steel turning structures on street corners will be removed and replaced with wood poles. In two of four locations, these poles will need to be supported by overhead cables connected to additional wood poles, which will be supported by guy-wires. Guy-wires are needed to ensure the poles stand upright.

Option C

  • Line and structures will remain as is. No further work will be completed.

Option C illustrates the existing structures located in between street corners. Option A and B would replace in-line structures with wood, reducing their height to 79 ft. This change would occur if Option A or B is selected based on feedback from attendees of the open house and from area residents.

Option C illustrates the existing structures located on street corners. In Option A, steel turning structures would remain but would be reduced in height by 10 to 12 ft. Option B would replace corner steel structures with wood. The wood poles will require additional poles and guy-wires to anchor them. This change would occur if Option A or B is selected based on feedback from attendees of the open house and from area residents.

The illustration below shows that transmission poles along Mossman and Green streets will be replaced with poles that are closer to the roadway. This change would occur if Option A or B is selected based on feedback from attendees of the open house and from area residents. Option C illustrates the existing structures.

The illustration below shows the diameter of the existing steel poles versus the diameter of the wood poles to be installed if Option A or B is selected, based on feedback from attendees of the open house and from area residents.

Mossman and Green

This is the existing structure at the southeast corner of Mossman and Green streets. Option A would reduce the height of this structure by approximately 10 ft. The shorter corner structures would occur if Option A is selected based on feedback from attendees of the open house and from area residents.

The mocked-up images below show an anchored wood pole replacing the steel pole at the southeast corner of Mossman and Green. The wood pole requires additional poles and guy-wires to anchor it. This approach would be used if Option B is selected based on feedback from attendees of the open house and area residents.

11th and Green

This is the existing structure at the intersection of 11th and Green streets.

The mocked-up images below show a new wood pole with secondary wood poles and anchoring wires that could be placed at 11th and Green if Option B is selected based on feedback from attendees of the open house and area residents.
