Bill would require rate reviews for very large electric customers

The Public Service Commission would define a very large customer class or subclass for each electric utility. The commission would set the definition and characteristics for each utility. The commission would have to issue its order by December 15, 2027. It could act in a utility rate case or another proceeding.

An electric utility offering a tariff or contract rate to a very large customer would file a rate case application with the commission. The customer must belong to a very large customer class or subclass defined by the commission. The commission chair could waive the deadline if the utility showed exceptional circumstances requiring a waiver. The application would be due by April 1 every other year.

In a rate case, the utility would provide service-cost information, and the commission would review the rate and adjust rates or service terms if required. The review would cover service to a very large customer under a tariff or contract rate. The commission would set rules for the information utilities must provide about how current or proposed rates cover service costs. If the commission found rates unreasonable, preferential, or unjustly discriminatory, it would adjust rates or service terms to bring them into compliance. The provisions would first apply to a tariff or agreement submitted for commission review on the subsection’s effective date; the text does not state that date.
