Arizona has issued new net metering rules which apply to all investor-owned and cooperative utilities within Arizona. Under these new rules, net metering becomes available to all customers who generate their own electricity through solar power , wind power, hydroelectric, geothermal, biomass, biogas, combined heat and power (CHP), or fuel cell technologies.
No firm kilowatt limit on system size capacity has been set. Instead, a system must be sized to meet all or part of a customer’s electric load, and the system may not exceed 125% of the customer’s total connected load.
Net metering is made possible through the use of a single bi-directional meter. Any customer net excess generation (NEG) will be carried over to the customer’s next bill at the utility’s retail rate, as a kilowatt-hour (kWh) credit. Any NEG remaining at the customer’s last monthly bill in a calendar year will be paid to the customer, via check or billing credit, at the utility’s avoided cost payment.
