Enbridge is proud to be working with the Tennessee Valley Authority (TVA) on a project that would provide affordable and cleaner energy for the utility’s customers.
Enbridge is proposing to design, construct and operate the Ridgeline Expansion Project (Ridgeline), an expansion of Enbridge’s existing East Tennessee Natural Gas (ETNG) system.
The purpose of this proposed project is to provide natural gas to serve one of the power generation options that TVA is currently considering to replace the Kingston Fossil Plant. Replacing coal-fired generation at the Kingston Fossil Plant with natural gas would provide Tennesseans with a lower-carbon, cleaner-burning energy source as we transition toward the future.
The proposed scope includes the installation of approximately 117 miles of 30-inch pipeline looping, an approximately 8-mile 24-inch lateral, and one electric-powered compressor station.
The majority of the route for the proposed pipeline would be located within the existing system’s right-of-way where possible to minimize impacts to landowners and the environment.
Ridgeline is in the preliminary phase of project development. Should both Enbridge and TVA reach a positive final investment decision to move forward with the project, there will be many opportunities for public review and input during the multi-year regulatory review processes. Our focus is to engage with local stakeholders to discuss the details of the proposed project and work with landowners to identify the best route prior to engaging regulatory agencies.
All necessary regulatory authorizations from the Federal Energy Regulatory Commission (FERC) and other federal and state agencies are required before the construction of the project can commence. Pending a positive final investment decision and the approval and receipt of all necessary permits, construction would begin in 2025 with a target in-service date of fall 2026.
