Solar and net metering
Commonwealth Edison Co reports 65,704 residential solar installations to the EIA, totalling 479.24 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, Commonwealth Edison Co collected an average of $0.1339 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.
