Ridgeline Expansion Project Opportunity

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.

We are 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.

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 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.

Project overview:

• Type: Natural gas pipeline
• Status: Under review
• Expected to transport: Natural gas
• In-service target date: Fall 2026
• Ownership: Enbridge Inc. (100%)
