Solar and net metering
Public Service Co of NH reports 16,580 residential solar installations to the EIA, totalling 133.407 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, Public Service Co of NH collected an average of $0.1875 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.
