Michigan Compiled Laws, Chapter 460. Public Utilities § 460.1329

(a) Defend, indemnify, and hold harmless the authority or the governing body of a municipally owned electric utility and its officers, agents, and employees against any claims, demands, damages, lawsuits, judgments, costs, liens, losses, expenses, and attorney fees resulting from the installation, construction, repair, replacement, operation, or maintenance of any wireless facilities, wireless support structures, or utility poles to the extent caused by the applicant, its contractors, its subcontractors, and the officers, employees, or agents of any of these. A wireless provider has no obligation to defend, indemnify, or hold harmless an authority or the governing body of a municipally owned electric utility, or the officers, agents, or employees of the authority or governing body against any liabilities or losses due to or caused by the sole negligence of the authority or the governing body of a municipally owned electric utility or its officers, agents, or employees.

(b) Obtain insurance naming the authority or the governing body of a municipally owned electric utility and its officers, agents, and employees as additional insureds against any claims, demands, damages, lawsuits, judgments, costs, liens, losses, expenses, and attorney fees. A wireless provider may meet all or a portion of the authority's insurance coverage and limit requirements by self-insurance. To the extent it self-insures, a wireless provider is not required to name additional insureds under this section. To the extent a wireless provider elects to self-insure, the wireless provider shall provide to the authority evidence demonstrating, to the authority's satisfaction, the wireless provider's financial ability to meet the authority's insurance coverage and limit requirements.
