In a joint filing with the New Jersey Board of Public Utilities, Southern Company and AGL Resources requested regulatory approval of the companies' proposed merger. AGL Resources is the parent company of Elizabethtown Gas. When completed, the combination of Southern Company and AGL Resources is expected to create the second-largest utility company in the U.S. by customer base. The newly merged company will have 11 regulated electric and natural gas distribution companies providing service to approximately 9 million customers, nearly 200,000 miles of electric transmission and distribution lines, more than 80,000 miles of gas pipelines and approximately 46,000 MW of electricity generating capacity. The companies expect to complete the transaction in the second half of 2016.
