Solar and net metering
Kauai Island Utility Cooperative reports 6,221 residential solar installations to the EIA, totalling 28.87 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, Kauai Island Utility Cooperative collected an average of $0.3843 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.
