Solar and net metering
United Illuminating Co reports 23,614 residential solar installations to the EIA, totalling 144.676 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, United Illuminating Co collected an average of $0.3106 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.
