FlexPlan, TruBalance and PriceCap price plans and rates effective %%EffectiveDate%% to %%ExpirationDate%% and subject to our terms and conditions of service. The variable rate component of our currently available plans including a monthly per therm price are based on a publicly available index using the following formula: the sum of: (1) Natural Gas Intelligence (NGI) Chicago Citygate first-of-month (FOM) index price*, converted to a price per therm, and (2) 23¢ per therm. Currently available variable rate prices based on this formula are posted on the Illinois Energy website before the end of the first business day of every month. Variable rate prices based on an index representing market prices may change or remain the same each month based on market conditions. Market prices and indices can be highly volatile and there is no limit on how much the price per therm may change from one billing cycle to the next.

*The NGI FOM index price represents the market value of natural gas in the wholesale market for a particular location (Chicago Citygate), over a specified period of time. NGI is a natural gas price reporting agency. For more information visit: https://www.naturalgasintel.com/.
