eligibility with the utility before switching.
Duke Energy Carolinas, LLC reports 37,057
residential solar installations to the EIA, totalling
278.977 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, Duke Energy Carolinas, LLC collected an average of $0.1395
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.
