Solar and net metering

Salt River Project reports 63,437 residential solar installations to the EIA, totalling 435.41 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, Salt River Project collected an average of $0.1398 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.
