Notwithstanding any other provision of this Chapter or any other provision of law, any public utility, as defined by G.S. 62‑3, shall pay to its customers such rate of interest as may be required by order of the North Carolina Utilities Commission in transactions wherein the utility is refunding to its customers funds advanced by or overcollected from the customers.
