Energen Corporation, headquartered in Birmingham, Alabama, traces its beginnings to October 14, 1852. On that date, John Jeffrey and Company of Cincinnati, Ohio, received a franchise from the City of Montgomery to provide street lighting using manufactured gas. Montgomery Gas Light Company purchased the franchise in 1853 and a year later, the first street gaslights were in operation. Since 1854, the Company has experienced mergers, acquisitions, divestitures, and name changes. In 1937, Southern Natural Gas Company organized the utility into Alabama Gas Company and in 1948 merged it with Birmingham Gas Company to form Alabama Gas Corporation. The Company spun off from Southern Natural in 1953, becoming an independent and publicly traded company. Positioning itself for the future in 1974, the Company formed Alagasco, Inc., a holding company, with Alabama Gas Corporation as its primary subsidiary. In 1985, the holding company became Energen Corporation. Today, Energen Corporation is a diversified energy company with two major subsidiaries, Alagasco, its natural gas utility, and Energen Resources, its oil and gas acquisition and production company.
