Good news in the new year: Natural gas prices fall 

Natural gas prices have fallen from last month for most Illinois utilities, and they’re down across the board from last January — the perfect way to start off the new year. 

The price per therm you will pay for your natural gas in the month of January, also known as the Purchased Gas Adjustment, or PGA, is shown in the chart below. It includes PGAs from this month, last month and January 2019. Hover your mouse over the graphic to show prices.

Similar to last month, Mount Carmel customers experienced the biggest drop, down 16.3 cents per therm from December, a decrease of 28 percent from last January. The eastern Illinois utility still offers the highest price per therm in the state, but it’s nowhere near the company’s 2019 high of 70.6 cents per therm last November.

Nicor currently offers the lowest price at 26 cents per therm. The utility’s price has been steadily decreasing since June 2019, when it peaked at 37 cents.

Just three utilities increased their price from December: MidAmerican Energy, Liberty Utilities and Illinois Gas. But even these jumps were small, with respective increases of about 1.4 cents per therm, 2.2 cents and 0.46 cents.
