Seminole-Muskogee Transmission Line

Client: Oklahoma Gas & Electric
Location: Oklahoma


Oklahoma Gas & Electric (OG&E) retained Burns & McDonnell to conduct a routing review for the construction of approximately 125 miles of new transmission line from its existing Seminole Power Plant east of Konawa, Okla., in Seminole County to its existing Muskogee Power Plant in Fort Gibson, Okla., in Muskogee County. The study area for this project includes portions of Seminole, Hughes, Pittsburg, Latimer, Haskell, Muskogee, McIntosh, Okmulgee, Okfuskee and Pontotoc counties.

Burns & McDonnell assisted in the identification of a study area, development of alternative routes, and selection of a preferred route for the proposed project.

The project consists of more than 100 miles of 345-kV electric transmission line on a single 345-kV circuit on steel H-frame structures within a 150-foot-wide right-of-way. The selected route included using an existing line and the relocation and rebuilding of the existing line into the Muskogee Power Plant using new right-of-way.

The proposed transmission line would require approximately 85 miles of new construction as well as approximately 30 miles of existing line rebuild along OG&E's Pittsburg-Muskogee 345-kV line and relocation of the Pittsburg line within new right-of-way identified as part of the project. It would connect OG&E's Seminole Power Plant Substation with its Muskogee Power Plant Substation. Burns & McDonnell developed alternative routes for the proposed project and completed an environmental assessment (EA) of the route. Potential project impacts included wetlands, floodplains, threatened and endangered species (American burying beetle), migratory birds, and cultural resources. In addition, Burns & McDonnell conducted a cultural resources survey of the areas proposed for new construction. An EA was completed for the Bureau of Indian Affairs (BIA) to provide documentation for easement acquisition across properties of BIA interest.

Burns & McDonnell met with local officials, state and federal agencies and other key stakeholders during the routing process. Burns & McDonnell also assisted in conducting four public open houses. Burns & McDonnell is providing permitting services, cultural surveys, threatened and endangered species surveys, right-of-way acquisition management, and complete design services for the project from surveying through construction management.
