If the affected retail electric suppliers, excluding municipal electric providers, are unable to agree to a division of the affected area within the applicable six-month period, either retail electric supplier shall have sixty (60) days in which to notify the Corporation Commission of the inability of the retail electric suppliers to negotiate a division of the affected area. Upon receipt of the notice, the Corporation Commission shall, within six (6) months, divide the affected area among the affected retail electric suppliers based upon projected sales and other criteria so that each affected retail electric supplier shall have, as nearly as is reasonable, an approximately equal share of the projected economic benefits associated with the extension of retail electric service to new electric-consuming facilities in the affected area. When dividing the affected area so as to achieve equal shares of the future growth in projected economic benefit of providing retail electric service in the affected area, the Corporation Commission shall not consider the economic benefits associated with serving retail electric customers existing prior to the order dividing the affected area between retail electric suppliers. The Corporation Commission shall consider economic projections provided by the affected retail electric suppliers. The Corporation Commission may choose to employ or contract with an independent consultant to provide economic projections, in which case the reasonable, ordinary and necessary costs of the consultant shall be borne equally by the affected retail electric suppliers. In all cases, criteria upon which the Corporation Commission makes its determination shall include public safety, current and projected population, existing electric service, current and anticipated municipal zoning, potential customer revenue, quality of electric service, cost to provide electric service, growth potential over a ten-year period, conservation of natural resources and materials and efficient use of public rights-of-way. After making its determination, the Corporation Commission shall issue an order dividing the territory among the affected retail electric suppliers. An order by the Commission, dividing the affected area between the affected retail electric suppliers, shall provide each retail electric supplier, as nearly as is reasonable, an equal share of the future growth in projected economic benefit of providing retail electric service in the affected area. In no event, however, shall the Corporation Commission issue an order that affects the right of a retail electric supplier to continue serving existing customers in the affected area that the retail electric supplier was serving prior to the effective date of the Commission order except as otherwise provided by law; and
