Solar and net metering
Idaho Power Co reports 18,434 residential solar installations to the EIA, totalling 142.49 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, Idaho Power Co collected an average of $0.1174 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.
