RLBA assessed alternatives to existing coal movements between Appalachian coal origins and GRU’s generating station in Hague, Florida. Transportation supply alternatives were sought to possibly negate sole-source railroad service to GRU’s plant. RLBA conducted a detailed economics analysis of various coal transportation supply options including the construction of a new rail line along various routes, each of which would connect the plant with an existing line of a railroad competitor, promising substantial savings compared with the existing carrier. GRU saved over $500 million as a result of such efforts.
