Ind. Code § 8-1-2.2-22
That part of a project owned by a municipality or municipalities or joint agency shall be exempt from property taxes. However, each municipality participating in a project or joint agency owning all or any part of a project shall, in lieu of property taxes, pay to any governmental unit authorized to levy property taxes the amount which would be assessed as taxes on real and personal property of a project if such project were otherwise subject to valuation and assessment. Such payments in lieu of taxes shall be due and shall bear interest if unpaid, as in the cases of taxes on other property. Payments in lieu of taxes made under this section shall be treated in the same manner as taxes for purposes of all procedural and substantive provisions of law.
Except as expressly provided in this section with respect to jointly owned projects, no other property of a municipality used or useful in the generation, transmission and distribution of electric power and energy shall be subject to payments in lieu of taxes.
