Seven thousand dollars per pole mile of transmission line owned or leased by the taxpayer greater than three hundred kilovolts. b. The replacement transmission tax shall be calculated on the basis of pole miles of transmission line owned or leased by the taxpayer on the last day of the tax year. 2. In lieu of the replacement transmission tax imposed in subsection 1, a municipal utility whose replacement transmission tax liability for the tax year 1999 was limited to the tax imposed by this section and whose anticipated tax revenues from a taxpayer, as defined in section 437A.15, subsection 4, for the tax year 1999, exceeded its replacement transmission tax by more than one hundred thousand dollars shall be subject to replacement transmission tax on all transmission lines owned by or leased to the municipal utility as of the last day of the tax year 2000 as follows: a. Three thousand twenty-five dollars per pole mile of transmission line owned or leased by the taxpayer not exceeding one hundred kilovolts. b. Seven thousand dollars per pole mile of transmission line owned or leased by the taxpayer greater than one hundred fifty kilovolts but not exceeding three hundred kilovolts. 3. The following shall not be subject to the replacement transmission tax: a. Transmission lines owned by or leased to a municipal utility when devoted to public use and not for pecuniary profit, except transmission lines of a municipally owned electric utility held under joint ownership and transmission lines of an electric power facility financed under chapter 28F or 476A. b. Transmission lines owned by or leased to a lessor when the transmission lines are subject to the replacement transmission tax payable by the lessee or sublessee. c. Any electric cooperative which owns, leases, or owns and leases in total less than seven hundred fifty pole miles of transmission lines in this state. Chapter 437 shall apply to such electric cooperatives. d. Transmission lines owned by or leased to a state university or university of science and technology, provided such transmission lines are used exclusively for the transmission of electricity consumed by such state university or university of science and technology. e. Transmission lines owned by or leased to a person, other than a public utility, for which a franchise is not required under chapter 478. 4. For purposes of this section, if a transmission line is jointly owned or leased, the taxpayer shall compute the number of pole miles subject to the replacement transmission tax by multiplying the taxpayer’s percentage interest in the jointly held transmission lines by the number of pole miles of such lines.
