Amend CSSB 7, Sec. 40.059, by adding a new subsection (g) to read as follows: (g) The municipal power agency, or its successor(s) in interest, may at its option, use the rate of return method for calculating its transmission cost of service. If the rate of return method is used, then, the return component for the transmission cost of service revenue requirement shall be sufficient to meet the transmission function's pro-rata share of levelized debt service, and debt service coverage (1.50) and other annual debt obligations; provided that, the total levelized debt service does not exceed the total debt service under the current payment schedule. Any additional revenue generated by the foregoing methodology shall be applied to reduce the agency's outstanding indebtedness.
