Northern Illinois Gas was formed in 1954 from several companies in and around Ottawa, Ill. In 1955, we bought Union Gas and Electric, and a few years later, we laid the groundwork for the world's largest underground gas storage system. In the 1960's, we expanded our service area and began drilling for natural gas. During this time, we also increased our natural gas storage capacity by developing underground storage.
In 1997, Northern Illinois Gas began operating its natural gas business as Nicor Gas. Today, Nicor Gas is the largest natural gas distributor in northern Illinois, serving more than 2.2 million customers.
