Solar and net metering
Potomac Electric Power Co reports 61,215 residential solar installations to the EIA, totalling 470.58 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, Potomac Electric Power Co collected an average of $0.2147 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.
