Santanna, unlike most competitors, leaves the benefit of storage to our customers. Storage is an integral part of almost every deregulated gas transportation program offered by utilities in the state of Illinois. Even if a customers program is based upon a fixed sales price, storage offers the benefit of leveling your gas bills from summer to winter. Higher bills in the summer, but lower bills in the winter. Although a Santanna competitor also fills storage during the summer with typically less expensive gas, they do not bill the customer for the storage gas during the summer. During the winter, this less expensive stored gas is delivered to the customer, at the typically higher winter prices. The supplier has the benefit of Storage.
