Arizona Rate Case Decision Delays Solar Tariff Revisions

In approving new rates for UNS Electric, the Arizona Corporation Commission has delayed a decision on net energy metering (NEM) tariff and demand charges for residential solar until the completion of its Value of Solar (VOS) study. The decision reflects the importance of data-driven decisions to prevent adverse impacts to the growing solar industry as utilities continue to seek rate structures that meet customers’ evolving usage patterns, reduce cross-subsidies, and enhance recovery of fixed costs.
