Eastern Transmission Line Project
Eastern Transmission Line Background
Since 2005, Your Own Utilities has been working on the approved City Commission route for the Eastern Transmission Line. This line is important to our community in order to increase electric reliability in the eastern part of Tallahassee, where development has outpaced construction of electric transmission lines and substations.
The approved route, referred to as the "Welaunee route" in the Commission Agenda Item, was recommended by staff as the most viable of three alternatives based on the following criteria: public input, reliability, economics, impact on community and environmental concerns.
A contractor (MasTec) was hired to install the underground portions of the project. MasTec has completed the work on Dempsey Mayo road and through the Miccosukee Greenway. The remainder of this portion of the project is currently in the permitting process.
The overhead portions were bid this past summer and the same contractor has been approved by the City Commission to construct these portions. Your Own Utilities is currently working to get contracts in place and receive materials so that this part of the project can be started by November 2008. The first open house event for the construction south of Mahan Drive was held October 23 and the second open house was held November 6.
The Welaunee route runs overhead along Mahan Drive to Buck Lake Road, then underground north along Dempsey Mayo Road; then, using both overhead and underground installations through Welaunee property. At I-10 the route travels north to a new substation 14 to be built near Centerville and Shamrock Roads. Where the route intersects I-10, it will also run east down I-10 (pending approvals) to a new substation 17 to be built near Mahan Drive/US 90 just past its intersection with I-10.
