About the Project

The Midwest Transmission Project is one of several ‘Priority’ projects determined by the Southwest Power Pool’s (SPP) Board of Directors and Members Committee in April of 2010. The Midwest Transmission Project will better integrate SPP’s east and west regions, improve SPP members’ ability to deliver power to customers, and facilitate the addition of new renewable and non-renewable generation to the electric grid. SPP is a Regional Transmission Organization with members in Arkansas, Kansas, Louisiana, Mississippi, Missouri, Nebraska, New Mexico, Oklahoma, and Texas that serve more than five million customers.

The Midwest Transmission Project will provide an alternate route for electricity during emergencies and greater service reliability for all electric utility customers across northwest Missouri, eastern Nebraska and throughout the surrounding region.
   
The Midwest Transmission Project will reduce congestion on the region’s transmission system and provide additional transmission capacity needed for long-term efficient delivery of energy to our customers and our region.
   
The Midwest Transmission Project will provide future access to affordable renewable power for all electric utility customers across northwest Missouri, eastern Nebraska and throughout the surrounding region.
   

The Midwest Transmission Project is a partnership project being accomplished by KCP&L and OPPD. The Project includes planning, routing, and construction of a new 345-kV transmission line from KCP&L’s existing Sibley Substation located near Sibley, Missouri to the new Mullin Creek Substation south of Maryville, Missouri and on to OPPD’s existing Substation 3458 located at their Nebraska City Power Station south of Nebraska City, Nebraska.

The Midwest Transmission Project team, after receiving input from area residents, community leaders, landowners and other stakeholders, has determined a final route for construction of the new transmission line. The final route selection is a culmination of an extensive year-long information gathering process by the Midwest Transmission Project.

In order to select a route that maximizes benefits and minimizes impacts to the community, the team hosted 20 public meetings throughout the project area, which were attended by more than 2,000 residents. In addition, we met with local officials and various government agencies, and sought and received significant feedback throughout the year. The combination of this feedback has been a crucial component in the route selection process. In addition to input from stakeholders, we identified and evaluated all potential routes using physical and social criteria including proximity to residences and businesses, land use, wetlands, and other natural resources.

We thank all of the thousands of people who have provided valuable input throughout the entire process.

The Mullin Creek Substation
The Mullin Creek Substation will be located south of Maryville, Missouri. The substation location was selected due to its proximity to existing lines and necessary resources, the size and geography of the property available, and the natural screening and landscape development abilities to minimize visual and environmental impact. The Project team is working with neighbors to provide information about the substation development process, the overall Project, and the team’s commitment to creating adequate buffering and landscaping. The Mullin Creek Substation will support energy reliability for the region as well as provide opportunities for additional resources in the future.
