Like many goods and services we use every day, the price of natural gas has increased.  Click here to learn more about why natural gas prices have increased.

Illinois Energy is one of the region’s premier alternative natural gas suppliers. We want to make sure you are equipped with the right tools to manage your natural gas budget.

We recommend that customers consider our Guaranteed Bill Plan. The Guaranteed Bill plan guarantees you’ll pay a flat monthly bill amount for 12 months regardless of changes in gas prices or weather.* We also offer PriceGuard Plans that come in a variety of term lengths and help protect you from further increases in natural gas prices by locking in a fixed price per therm.* Click here to find the plan that best suits your needs.

Selecting the right price plan is an important part of protecting your budget this winter – but that’s not all you can do. Below are several additional tips to help reduce the impact of these rising costs.

How can I manage my natural gas costs?

  • Turn your thermostat down when you’re away or asleep. You can save as much as 10% a year on energy costs by turning your thermostat back 7-10 degrees for 8 hours a day. Many thermostats can even be programmed to automatically turn down the temperature during times you know you’ll be out of the house or asleep.
  • Ensure your heating system is operating efficiently. A clean system is an efficient system. Clean or replace furnace filters once a month or as recommended. Clean warm-air registers, baseboard heaters, and radiators as needed. Make sure your heating system isn’t blocked by furniture, carpeting or drapes.
