(a) Notwithstanding the requirements of Subchapter F, the utility commission may authorize an emergency rate increase for a utility for which a person has been appointed under § 13.4132 or for which a receiver has been appointed under § 13.412 if the increase is necessary to ensure the provision of continuous and adequate services to the utility’s customers. The commission and utility commission shall coordinate as needed to carry out this section.
(b) A utility that receives an emergency rate increase under this section shall provide to each ratepayer notice of the increase as soon as possible, but not later than the first utility bill issued at the new rate.

(c) An emergency order may be issued under this section for a term not to exceed 15 months. The utility commission shall schedule a hearing to establish a final rate within 15 months after the date on which an emergency rate increase takes effect. The utility commission shall require the utility to provide notice of the hearing to each customer. The additional revenues collected under an emergency rate increase are subject to refund if the utility commission finds that the rate increase was larger than necessary to ensure continuous and adequate service.
