De Soto Transmission & Substation Upgrades

Evergy is preparing to complete infrastructure upgrades in De Soto, Kansas, to enhance electric reliability, strengthen the regional power grid and support growth in the area.

Clearview substation new build

  • Evergy built a new substation near 95th Street and Sunflower Road.
  • The construction of the new substation will allow for the removal of an aging substation on the north side of De Soto in 2026.

95th and Waverly-Clearview transmission line rebuild

  • Evergy will rebuild the existing 3.4-mile transmission line between the 95th and Waverly (95th Street and Waverly Road) substation to Clearview (95th Street and Sunflower Road) substation.
  • All existing poles on the south side of 95th Street between Lexington Ave and the 95th and Waverly substation will be shortened to remove the transmission line wires at the top. The shortened poles will remain to support distribution line equipment.
  • The existing transmission line has been in place since the 1970s. Upgrading the transmission line ensures the equipment meets modern standards for reliability and safety.
  • Existing wood single poles will likely be replaced with steel single poles. Existing structures that require guywires for support will likely be replaced with self-supporting steel structures. Steel poles are utilized for reliability and resiliency with the harsh weather conditions our communities can face.
    • Poles will likely be 80 to 100 feet tall. Existing structures are 60 to 90 feet tall.
    • The space between each pole will likely be between 300 to 400 feet. Existing structures are about 250 to 400 feet apart.
    • The base of each pole will likely be 3 to 7 feet in diameter. Existing structures have a 2.5 feet diameter base.
  • Construction is scheduled to begin in January 2024 and be completed in June 2024.
  • Vegetation trimming and removal will be required for the safe construction of operation of the transmission line. This will begin in Fall 2023.

345 kV transmission line new build

Evergy will build a 5-mile section of new transmission line to connect into the existing transmission line in the area.

  • Two separate transmission lines will run parallel to each other, likely utilizing steel single poles. Steel poles are utilized for reliability and resiliency with the harsh weather conditions our communities can face.
    • Poles will likely be 80 to 135 feet tall.
    • The space between each pole will likely be between 600 to 1,000 feet.
    • The base of each pole will likely be between 4 to 8 feet in diameter.
  • Construction is scheduled to begin in July 2024 and be completed in May 2025.

In addition to transmission and substation projects, Evergy will upgrade distribution infrastructure to serve homes and businesses in the community.

How will my property be restored after construction?
Property restoration will begin after construction is complete. Duration of restoration is weather dependent, but properties will be restored to, near as reasonable, pre-construction condition. An Evergy project representative will communicate with you to discuss damage, if any, caused by construction.

How was property acquired for the project?
We are committed to transparent and timely communications with landowners. We contacted landowners who have property on the transmission line route to discuss the project and are purchasing the easements necessary to build the line. One-time payments are provided based on the determination of market property values in the local area. We also discussed what to expect from our construction efforts and restoration practices.

What if Evergy can't come to an agreement with property owners?
Fortunately, that is a rare occurrence. Evergy will make every effort to reach negotiated agreements. Evergy may exercise the right of eminent domain to obtain an easement after exhausting attempts through negotiations with a landowner.

Will there be any restrictions on the use of my property?
Our easements allow property owners to continue most uses of their property, including planting crops, pasture and roadways. The existence of a transmission line easement does restrict some possible uses for property, including limiting the amount of allowed grade change, restricting buildings or structures within the easement area and restrictions on planting trees that may grow into the power lines.

What are the existing easement rights?
For Evergy’s projects, the easement permits surveys, construction, operation and maintenance of distribution and transmission lines and other equipment. The easement also permits ingress and egress to the easement and permits the trimming and removal of trees, on or adjoining the easement, that may interfere with the safe and reliable operation of the power lines.

Why are the new easements larger than existing easements?
To meet modern standards for reliability and safety, a wider easement is required to accommodate the area in which the line will blow or sway between poles.

Why do the easement sizes vary?
The easements vary from property to property, but the overall easement width throughout the corridor is 100 feet wide for each 115 kV line and 150 feet wide for each 345 kV line. However, the centerline of the corridor is not the property line. As such, the easement may be wider on one property as opposed to another property.

Why are access rights needed on all properties?
This is a continuation of our existing rights. Once the line is constructed, our use of the provision will look like our past practices. We need access rights for equipment repairs, maintenance or to restore power during an outage. Since the new line will be built to modern standards, our need to access it may be less frequent. An Evergy project representative will communicate with property owners to discuss and compensate for any damage caused by maintenance.

Are the easements maintained by Evergy?
We strive to be good neighbors and stewards of the communities we serve. We repair and maintain the power equipment within the easement. We also keep vegetation trimmed away from the power equipment within the easement. If there is an issue, please contact us and we will do our best to resolve it. While we will trim and/or remove vegetation to ensure the safety and reliability of our transmission line, it is the responsibility of the landowners to maintain their property.

How will you communicate with property owners affected by the project?
We are hosting an informational open house before construction begins. Property owners along the line route received meeting information, but anyone could attend. Justin Rexwinkle, project representative, will be available for the duration of the project to provide information, answer questions or address property owners’ concerns. Justin can be reached at 620-252-5452 or Justin.Rexwinkle@evergy.com.

Who will benefit from the project?
This project will benefit residents and businesses in De Soto, eastern Kansas and beyond by strengthening the regional power grid and enhancing reliability. It also will provide tax revenue, construction jobs, local expenditures and will expand capabilities for future investment in area business and industry.

Who is responsible for this project?
Evergy will construct and own the new substation and transmission lines. The Southwest Power Pool (SPP) operates the transmission system in the region for this transmission line. SPP will direct Evergy to operate the new transmission line.

Who will build the lines and manage the construction?
Evergy will design and construct the transmission line using both Evergy resources and subcontractors depending on the task. Evergy will provide project management services and coordination during construction of the project.

What environmental impacts will be considered with the siting of the project?
Evergy believes the environment is an important factor when planning and designing transmission line projects. We work closely with appropriate organizations, including the Kansas Department of Wildlife, Parks and Tourism, Kansas Historical Society, the U.S. Fish and Wildlife Service and the Nature Conservancy from the beginning of projects to make sure any direct environmental impact is appropriately identified and addressed. We believe this kind of collaboration leads to developing a transmission line route that aligns with federal and state energy and environmental policy objectives. We adhere to all state and federal regulations to protect native plants, threatened or endangered species, wetlands and water and air quality.
