N.C. Gen. Stat. § 62-133.12A: Customer usage tracking rate adjustment mechanisms for water and wastewater rates.

In setting rates for a water and wastewater utility in a general rate proceeding under G.S. 62-133, the Commission may adopt, implement, modify, or eliminate a rate adjustment mechanism for one or more of the company's rate schedules to track and true-up variations in average per customer usage from levels approved in the general rate case proceeding. The Commission may adopt a rate adjustment mechanism only upon a finding by the Commission that the mechanism is appropriate to track and true-up variations in average per customer usage by rate schedule from levels adopted in the general rate case proceeding and the mechanism is in the public interest.
