About these numbers. Rates shown are averages computed from federal regulatory filings (EIA Form 861)
and public tariff databases — confirm with your utility before making decisions; your actual rate depends on your tariff,
usage, and riders. Distribution utility is determined by address and generally cannot be chosen; in retail-choice states
you may choose your supplier for the supply portion of the bill. Savings figures use 10,800 kWh/yr
(US average residential usage) and are estimates, not quotes. EnergySavings is an independent data project by CertiHomes
