KIUC asserted that it would present issues and develop facts related to electric rates and service that will assist the Commission in fully considering the matter without unduly complicating or disrupting the proceedings. KIUC stated that its member Catlettsburg Refining LLC, is a subsidiary of Marathon, which is the largest customer on the Kentucky Power system, purchasing approximately 15 percent of all energy sold at KRS 164.2807.
