Solar and net metering
Public Service Co of Colorado reports 121,127 residential solar installations to the EIA, totalling 720.347 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 Colorado collected an average of $0.1590 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.
