Nicor Gas

Gas utilities seek to increase rates by $7 to $10 per month next year

Nicor Gas, the state’s largest natural gas utility covering much of northern Illinois, is asking Illinois officials to approve a $309 million rate increase that, if approved, would raise a typical customer’s bill about $7.50 a month.

Nicor Gas warns of potential rotten-egg natural gas smell as it transfers odorant in Richmond area Wednesday.

Regulators at the Illinois Commerce Commission on Thursday unanimously approved rate hikes for four major natural gas utilities, but the little-known regulatory body’s decision was perhaps more notable for what it rejected

Residents across 37 counties that include the suburbs and much of northern Illinois will learn Thursday if Nicor Gas rates will spike by an average of $111 annually.
