A coalition of more than 15 business, manufacturing, and labor groups in Illinois have filed a petition with the state's Commerce Commission to halt the planned phaseout of natural gas in the state. The groups cite a recent study by three state agencies that found Illinois could face electricity shortages as soon as 2029 if baseload generation sources are retired as currently mandated by state law.

Why it matters

The push to transition away from fossil fuels like natural gas is a key part of Illinois' climate and clean energy goals. However, this petition highlights concerns from industry groups that moving too quickly on this transition could jeopardize the state's power supply and lead to potential shortages, which would have major economic impacts.

The details

The coalition, which includes groups like the Illinois Manufacturers' Association and the Illinois AFL-CIO, argues that the state's energy imbalance will only worsen if baseload generation sources like natural gas plants are retired as currently required by state law. They are urging the Illinois Commerce Commission to halt the phaseout plans until the potential power shortage issues can be addressed.
