Solar and net metering
Central Maine Power Co reports 12,880 residential solar installations to the EIA, totalling 107.057 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, Central Maine Power Co collected an average of $0.2237 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.
