Ridgeline Nears Startup; Court Shreds Ruling Against TVA Gas Plant
Enbridge's 122-mile Ridgeline Expansion Project in Tennessee is nearing completion, with service potentially starting Nov. 1, delivering 300 MMcf/d to TVA's Kingston site. A federal appeals court allowed construction to continue on the $2.5B gas plant the pipeline feeds, overturning a previous ruling.
