TX HB3157

Electric utilities operating solely inside ERCOT may implement interim rates on the 90th day after filing a statement of intent when the regulatory authority orders a rate suspension

Interim rates must be calculated using the utility's proposed test year cost of debt, rate base, and expenses, combined with the return on equity or debt service coverage from the utility's most recent base rate proceeding

Utilities must provide at least 45 days' notice to each retail electric provider in their service area before the interim rate takes effect

Utilities must refund any money collected under interim rates that exceeds the final ordered rate, plus interest at the utility's last approved rate of return

The commission may modify or deny interim rates upon finding exigent circumstances, and the changes apply only to rate proceedings initiated on or after the act's effective date
