Enbridge has plans to build a natural gas pipeline across Tennessee to get gas to one of Tennessee Valley Authority’s (TVA) planned gas-fired power plants (see Enbridge Gets Serious About New TN Pipe to Feed TVA Power Plant). Enbridge’s Ridgeline Expansion Project is an expansion of the company’s existing East Tennessee Natural Gas (ETNG) system. Ridgeline will feed 300 MMcf/d of natural gas to a TVA gas plant currently under consideration to replace the Kingston Fossil Plant (a coal-fired plant). Ridgeline includes the installation of approximately 110 miles of 30-inch pipeline looping, 4 miles of 30-inch-diameter header pipeline, an approximately 8-mile 24-inch lateral, and one electric-powered compressor station. Last week, the Federal Energy Regulatory Commission (FERC) announced it would prepare an environmental impact statement (EIS) for the Ridgeline project.
