ReliabiliTree Overview

ReliabiliTree is Westar's revitalized Vegetation Management Program that is beginning as a pilot program in the Wichita metro area.

Overview

• The pilot program will take about four years to complete. If successful, the project will be expanded to the entire Westar service territory.


• Intent will be to clear (remove) or prune trees first through the entire division and then maintain the vegetation by returning about every four to five years.


• Westar will periodically report the progress and results of the program to the Kansas Corporation Commission. Progress reports will be shared on this website soon.

Vegetation Management

• Vegetation management - clearing and pruning of trees - will be performed on a standard time cycle rather than selected based on reliability of service.


• Westar is increasing its education regarding the importance of keeping lines clear of trees and other vegetation.


• Westar will work to educate customers and communities regarding landscaping and tree planting with consideration to power line reliability and safety.


• The expected outcome is more reliable service and more efficient operations.

Outage Causes

In areas where we've cleared circuits of vegetation, we have seen a 50 percent to 70 percent reduction in tree-related power outages and 30 percent reduction overall.


As you can see from the graph above, vegetation is a significant cause of power outages. Trimmed back powerlines also decrease other outage causes, for example:

• It is more difficult for wildlife to come in contact with our equipment.


• Overhanging tree limbs often fall on powerlines during thunderstorms and ice storms.


• Will reduce "flickering lights" that can occur from vegetation momentarily touching power lines.
