Southern is a well established company with an excellent track record. We have been in the business for more than 150 years, delivering competitively priced natural gas energy to manufacturers, commercial and industrial customers, and all other natural gas markets.

1847	The State of Connecticut grants a charter to establish the New Haven City Gas Light Company. The first New Haven house to be lighted with gas was that of Professor Benjamin Silliman, Jr. on Hillhouse Avenue and was used for the first time on Thanksgiving Eve 1848. It was Professor Silliman who, along with five other prominent citizens of New Haven, had obtained the charter to establish the Company, or, as it came to be known, "The Gas." New Haven at that time had a population of 22,000, its commerce was active, and its industry had begun booming out of its infancy. Later in 1848, Durrier & Peck’s book store on Chapel Street, New Haven, became the first commercial dwelling lighted with gas. By 1850, the fledging company was selling more than five million cubic feet of gas a year.
1861	So phenomenal was the demand for gas illumination that the New Haven Gas Light Company, as it was now known, outgrew its original St. John Street plant. The company constructed a new plant at Chapel and East Streets capable of generating 500,000 cubic feet of coal gas.
1901	The Bridgeport Gas Light Company acquires Citizens Gas.
1939	The great industrial war expansion began and the use of gas gained growing acceptance of gas as an important industrial fuel. George S. Hawley, President of Bridgeport Gas, said: "I never thought that I should be called upon to ask you and our more than 45,000 other friendly customer to use less gas...The Gas Industry today is at the highest peak of all-time-greatest activity, greatest sales, and greatest progress in research and development. And now here I come and ask you to use less gas…to help those who are fighting this gigantic and terrible war on all fronts. They must have guns and ammunition, airplanes and parachutes, all of which are made right here by our Bridgeport workers. In order to manufacture them, they must have gas in great quantities for fuel. The government has declared gas to be a vital war necessity. Without it war industries would be paralyzed."
1947	To meet the growing demand following the war years, the Bridgeport Gas Company embarked on a major construction project to expand its distribution facilities. The project would ready the company for a major change in the industry – the arrival to New England of natural gas energy. The company switched from manufactured gas to natural gas in 1952. The demand for natural gas took yet another great leap forward. The Bridgeport Gas Light Company expanded its service territory to include shoreline communities from Westport to Stratford.
1955	The Bridgeport Gas Light Company changed its name to the Bridgeport Gas Company.
1962	On May 23, the Bridgeport Gas Company suffered a major fire, which destroyed the company’s service headquarters and appliance warehouse at 412 Housatonic Avenue, causing more than $100,000 in damage.
1967	This was a pivotal year in the company’s history. The Bridgeport Gas Company and the New Haven Gas Company merge to form The Southern Connecticut Gas Company. The Company moved into new headquarters at 880 Broad Street, Bridgeport, in 1969. The new structure featured a unique total energy system that generated all of the facility’s power, including electricity, using natural gas. Southern maintained service centers at 39 Pine Street, Bridgeport and 347 Chapel Street, New Haven, and an administration building at 55 Church Street, New Haven.
1979	Connecticut Energy Corporation is established as the parent company of The Southern Connecticut Gas Company to set the stage for the Company’s expansion and success.
1993	Southern moved into its current corporate headquarters at 855 Main Street in Bridgeport in 1993. The Company centralized its operations center at 60 Marsh Hill Road, Orange the following year. Connecticut Energy formed two new subsidiary companies: CNE Energy Services, Inc., which provides an array of energy commodities and services to commercial and industrial customers throughout New England and New York; and CNE Development Corporation, which participates in a natural gas purchasing cooperative. Connecticut Energy added a third subsidiary, CNE Venture-Tech in 1996. CNE Venture-Tech invests in ventures that offer technologically advanced energy-related products.
1997	The Company celebrated its landmark 150th Anniversary.
1998	Southern completed installation of the largest pipeline project in its history - an 11-mile, 16-inch gas distribution line, which delivers natural gas to a new 520-megawatt electric generating station at Bridgeport Harbor. Today, Southern stands as one of the premier suppliers of natural gas energy in New England.
1999	In April 1999, the Southern Connecticut Gas Connecticut Company embarked upon an exciting venture. Connecticut Energy Corporation, parent company of SCG, announced that it would file with the Connecticut Department of Public Utility Control (DPUC) an application for approval of its proposed merger with Energy East Corporation. The merger was approved by the DPUC in December 1999, and the merger was completed in February 2000. Energy East Corporation (NYSE:EAS) is a super-regional energy services and delivery company in the Northeast. Energy East is a leader in promoting competition and is committed to profitably growing its energy infrastructure. Energy East serves 2 million customers (1.4 million electricity and 600,000 natural gas) in upstate New York and New England.
