Tex. Utilities Code § 66.012

(a) The holder of a state-issued certificate of franchise authority shall indemnify and hold a municipality and its officers and employees harmless against any and all claims, lawsuits, judgments, costs, liens, losses, expenses, fees (including reasonable attorney's fees and costs of defense), proceedings, actions, demands, causes of action, liability, and suits of any kind and nature, including personal or bodily injury (including death), property damage, or other harm for which recovery of damages is sought, that is found by a court of competent jurisdiction to be caused solely by the negligent act, error, or omission of the holder of a state-issued certificate of franchise authority or any agent, officer, director, representative, employee, affiliate, or subcontractor of the holder of a state-issued certificate of franchise authority or their respective officers, agents, employees, directors, or representatives, while installing, repairing, or maintaining facilities in a public right-of-way. The indemnity provided by this subsection does not apply to any liability resulting from the negligence of the municipality or its officers, employees, contractors, or subcontractors. If the holder of a state-issued certificate of franchise authority and the municipality are found jointly liable by a court of competent jurisdiction, liability shall be apportioned comparatively in accordance with the laws of this state without, however, waiving any governmental immunity available to the municipality under state law and without waiving any defenses of the parties under state law. This subsection is solely for the benefit of the municipality and the holder of a state-issued certificate of franchise authority and does not create or grant any rights, contractual or otherwise, for or to any other person or entity.

(b) The holder of a state-issued certificate of franchise authority and a municipality shall promptly advise the other in writing of any known claim or demand against the holder of a state-issued certificate of franchise authority or the municipality related to or arising out of the holder of a state-issued certificate of franchise authority's activities in a public right-of-way.

(c) The commission shall have no jurisdiction to review such police power-based regulations and ordinances adopted by a municipality to manage the public rights-of-way.
