Solar and net metering
Arizona Public Service Co reports 182,632 residential solar installations to the EIA, totalling 1643.363 MW. That means exported power is likely to earn something here, though what an exported kWh is worth depends on state rules rather than on the tariff in most cases.
For reference, Arizona Public Service Co collected an average of $0.1645 per kWh from residential customers in the most recent EIA survey, across all its tariffs and all usage levels. A single tariff priced at 1,000 kWh a month will differ from that blended figure.
