Ind. Code § 8-1-2.2-20
A municipality or joint agency may contract for the planning, acquisition, construction, reconstruction, operation, maintenance, repair, extension, and improvement of generation, distribution, or transmission facilities within or without its corporate limits or those of its members, or may contract with other public or private entities to perform these functions, without advertising for bids or securing performance and payment bonds, except to the extent that its governing body determines that these actions are desirable in furtherance of the purposes of this chapter. Except as otherwise provided by this section, no contract shall be invalid or unenforceable by reason of nonperformance of the conditions required by any other law relating to public contracts.
