Summary

Eligibility and Availability

Net metering is available to investor-owned utility and electric cooperative customers who generate electricity using solar, wind, hydroelectric, geothermal, biomass, biogas, combined heat and power, or fuel cell technologies.* A net metering facility must be located on the customer’s premises.

System Capacity Limit

The Arizona Corporation Commission (ACC) has not set a firm kilowatt (kW)-based limit on system size capacity; instead, systems must be sized to not exceed 125% of the customer’s total connected load. If there is no available load data for the customer, the generating system may not exceed the customer’s electric service drop capacity.

Aggregate Capacity Limit

The ACC has not set an aggregate capacity limit for all net-metered systems in a utility’s territory. The utility must instead demonstrate to the ACC why such a cap should be allowed. Under the ACC rules, each utility must file an annual report listing the net metered facilities and their installed capacity for the previous calendar year.

Net Excess Generation

Net metering is accomplished using 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 the annual true-up period will be paid to the customer, via check or billing credit, at the utility’s avoided cost payment.

For customers taking service under a time-of-use rate, off-peak generation will be credited against off-peak consumption, and on-peak generation will be credited against on-peak consumption. The customer’s monthly bill is based on the net on-peak kWh and net off-peak kWh amounts. Any monthly customer NEG will be carried over to the customer’s next bill as an off-peak or on-peak kWh credit.

Additional Charges

The ACC requires that net metering charges be assessed on a non-discriminatory basis. Any new or additional charges that would increase an eligible customer-generator’s costs beyond those of other customers in the rate class to which the eligible customer-generator would otherwise be assigned must be proposed to the ACC for consideration and approval. The utility has the burden of proof in any such proposal.

In December 2013, in response to an application from the Arizona Public Service Company (APS) to address cost shifting, the ACC ordered a $0.70 per kW charge for all residential distributed generation systems installed on or after January 1, 2014.** The charge does not apply to customers with systems installed by December 31, 2013. APS is required to file quarterly reports with the number of new distributed generation installations per month, the size of those installations in kW, and the revenue collected from customers through the lost fixed cost recovery charge. The ACC’s decision may be found here. Other utilities have also proposed additional charges for customer-generators.

*Salt River Project and municipal utilities do not fall under the jurisdiction of the Arizona Corporation Commission, and are therefore not subject to the state net metering rules.

**The charge applies specifically to “distributed generation” systems, not “net-metered systems”. However, as net metering only applies to systems located on the customer’s premises, the charge will affect net metering customers. The charge only applies to APS customers.

    Annual review; no policy changes. The ACC has scheduled an evidentiary hearing for April 2016 to investigate the cost of serving customers with distributed generation, as well as the value provided by distributed generation.

36KW Wind Turbine, Power Produced Each Month

The charts below gives a rough estimate of the power produced each month by Change Wind Corporations 36KW Helical Wind Turbine, and by a rough estimate I mean, the wind changes daily and your not going to get a wind to blow steadily at 10mph for a whole month.

 The main reason for the chart is to show how much electricity can be produced each month which is a lot, and that’s in the present time, what will it be 5 years from now or 10-20 years from now.

The cost per kilo watt hour has risen 30% or more in much of the USA over the past 10 years, some places a lot more then 30% and costs will continue to rise as coal mines are shut down and demand continues to rise.

Take the numbers from the chart and add about 50% more to that total and that’s the amount of power Change Winds 36KW wind turbine will produce 10-15 years from now.
