Arizona Replaces Net Metering with Lower Export Rates in Landmark Decision

The Arizona Corporation Commission has approved a decision to replace retail-rate net metering with lower export rates that will be determined individually in each utility rate case based on short-term valuation methods. The decision, which concludes a three-year investigation into the value and cost of solar, grandfathers existing customers into current net metering plans for 20 years, while new customers are locked in for a shorter 10-year period, creating uncertainty over future rates.
