St. Joseph Transmission Line Upgrade
Transmission line upgrades enhance reliability and strengthen the power grid, allowing us to serve homes and businesses well into the future.
The St. Joseph Transmission Line project is a part of Missouri’s initiative to upgrade utility infrastructure. Find detailed timelines, project maps and design diagrams for the following projects below:
- Cook Road - St. Joseph
- Cook Road - Edmond Street
- Edmond Street - Lake Road - Alabama Street
- Industrial Park - Mochila - Lake Road
Timeline
Construction began October 2021 and is scheduled to be complete by Summer 2022. Property restoration will continue through Fall 2022.
Project Map
Design
Steel poles are utilized for reliability and resiliency with the harsh weather conditions our communities can face. Existing wood or steel single pole structures will likely be replaced with new steel single pole structures. Where possible, existing structures that utilize guy-wires for support will be replaced with steel self-supporting structures.

Overview
- We will build a new 3.3-mile 161 kV electrical transmission line to connect the existing Edmond Street substation, located at the southwest corner of Felix and Second streets, to the existing Lake Road substation, located southwest of Lower Lake Road and Highway 759.
- We will also build a new 1.3-mile 161 kV electrical transmission line to connect the existing Lake Road substation to the existing Alabama Street substation, located south of State Highway U.
Timeline
Construction is set to begin 2027 and be completed in Fall of 2028.
Route Selection
Evergy has contracted with a consultant to perform an evaluation of the area between the three substations to determine potential routes for the new transmission line. Potential routes were developed with the intent to minimize adverse impacts to residents, their land and the natural environment, while providing a technically viable and cost-effective route. Input received from residents in the area will help us determine which route should be selected for construction.
Design
The route for the new transmission line must be determined before engineers can determine structure types and heights, but the structures will be steel. Steel poles are utilized for reliability and resiliency with the harsh weather conditions our communities can face.

Real Estate
We are committed to transparent and timely communications with landowners. We will contact landowners who have property on the transmission line route and purchased the easements necessary to build the line. We will also discuss what to expect from our construction efforts and restoration practices. Our intent is to leave property in a state comparable to pre-construction.

Health and Environment
Evergy believes the environment is an important factor when planning and designing transmission line projects. We work closely with the appropriate organizations from the beginning of projects to make sure any direct environmental impact is appropriately identified and addressed.
Landowners
We are committed to transparent and timely communications with landowners. We contacted landowners who have property along the line route to share project information and purchase easements to rebuild the line, if necessary. We also discussed what to expect from our construction efforts and restoration practices. Our intent is to leave property in a state comparable to pre-construction.
What is an easement?
An easement is an interest in land that permits the use of land for a specific purpose. 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 electrical lines.
If an easement is granted, will there be any restrictions on the use of my property?
The existence of a transmission line easement restricts some possible uses for property. Acceptable uses include planting crops, pasture and roadways. The three most common restrictions include 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 lines.
How long will the easement exist?
Transmission line easements are permanent and recorded at county’s Register of Deeds Office.
Will access to my property be required prior to construction?
Access to the easement corridor may be required prior to construction for the purposes of tests, surveys and studies to determine environmental and soil conditions.
Will my property be restored?
Property restoration will take place after construction is complete. Duration of restoration is weather dependent and varies by project, but properties will be restored to, near as reasonable, pre-construction condition. An Evergy project representative will communicate with property owners individually to discuss expected timeline and damage, if any, caused by construction.
Will my trees be trimmed or removed?
Any tree located within the right-of-way limits that will interfere with construction or operations will need to be removed. Any trees with branches overhanging the right-of-way limits will need to be side trimmed. All work performed will be overseen by a trained tree professional.
