* Data obtained from owertochoose.org (Power to Choose) for the days from 9/1/2021 to 9/30/20211. The tables above list the lowest price in cents/kWh offered by each retail electricity provider (REP) for a given type of plan for a monthly usage of 1000 kWh. If more than one product was available from the same REP for a given type of plan, EnergySavings.com only included the one with the lowest rate in its analysis. Please note that as products and rates may change at any time in the day on Power to Choose; EnergySavings.com’s analysis is based on information captured in its single daily snapshot, and therefore cannot guarantee that every product and rate made available in the month has been captured. Please reach out to [email protected] if you feel that any meaningful data has not been captured and EnergySavings.com may, at its sole discretion, issue a correction to the report. The analysis is performed by excluding plans that are marked as “Minimum usage fees/credits”, “Time of Use”, and “Prepaid” according to the data captured from Power to Choose. For more information about the electricity plans mentioned in this report, please consult both the Electricity Fact Label (EFL) and Terms of Service (TOS) for those plans. Those documents are available on the Power to Choose site if the plan is still currently offered. The rates listed may differ if the REP has changed its pricing.
