Net Metering - Arizona

Net Metering is available to all grid tied consumers within the utility's service area .   

Members installing renewable electric generation projects at their homes/businesses can meet some or all of their own energy needs. They can further reduce their own energy costs and add energy to Columbus Electric's electric distribution system through net-metering.

Net metering allows homeowners/businesses to receive the full value for the electricity that their renewable energy system produces. The term, net metering, refers to the method of accounting for the electricity production of a renewable energy system. Net metering allows homeowners/businesses with such systems to use any excess electricity they produce to offset their electric bill. As the homeowner's/business’s system produces electricity, the kilowatts are first used for any electric load in the home/business. If more electricity is produced from the system than is needed by the homeowner/business, the extra kilowatts are fed into the utility grid.

At the end of the month, if a member has generated more electricity than they used, the utility will credit the customer for the net kilowatt-hours of energy supplied to the utility. Unused credits will be carried forward to the next billing period and will be used to reduce the kilowatt-hours supplied and billed by the Cooperative during the following billing period. Excess kilowatt-hours generated will be rolled from month to month. Each September, or when the account is closed, any unused credits for excess kilowatt-hours generated will be paid to the member at the utility's avoided cost of $0.02735. If the member uses more electricity than they generate, they pay for the difference at the established rate.
