Underground Storage
With our underground storage aquifers underneath the Illinois farmland, we are able to purchase gas when it is likely to be less expensive. We can store it throughout the year, and then retrieve it for customers during peak winter months. Storage fields also give us flexibility to deliver gas to customers who purchase their own supplies. This allows those customers to buy gas at the best price and store it for future use.
