Hartford Electric Light Company


The Hartford Electric Light Company (HELCO) is a defunct electrical company that was located on Pearl Street in Hartford, Connecticut. It was merged with the Connecticut Power Company in 1958 and later these became Connecticut Light & Power. It is in the Ann Street Historic District.

The history of the Hartford Electric Light Company (HELCO) begins with the Hartford Steam Company. The steam company built the originally brick building in 1880 (See 'The Hartford Electric Light Company, Pearl Street plant, circa 1902'). The building had about a dozen boilers for producing heat and steam for their customers. The steam company introduced a new technology in 1881, an electric generator. It was Hartford's first electric service.

The Hartford Electric Light Company (HELCO) in 1881 received its charter as an official company and took over the electrical part of Hartford Steam Company. At that time Hartford had about a thousand gaslights in 80 miles of the city streets. It began actual operations of the steam-powered electrical generating plant on Pearl Street in 1882.Austin Cornelius Dunham was the company's first president. The first major project the company did was electrical lighting to the Asylum Street railroad station in 1883. HELCO ultimately made Hartford the first city in America with an all-electric street lighting system.

Hartford Light and Power Company, HELCO's competitor, bought the steam company and HELCO eventually vacated by 1887. HELCO bought Hartford Light and Power Company in 1896. They then returned to their original Pearl Street plant. The Hartford Electric Light Company operated the first steam turbine by a public utility to produce electricity in America. The steam turbine electrical generator was called Mary-Ann. It was installed at their Pearl Street plant in 1901. The Pearl Street plant also powered the city's street cars. The plant became a substation in 1905 when HELCO's Dutch Point plant was constructed and put in full operation.

Dutch point in Hartford was so named because the Dutch under Adrian Block landed there in 1614, which was about two decades before the English settlers came there. This plant started in operation in 1905, and before this the main electricity supply for the city of Hartford came from the original Pearl street plant of the Hartford Electric Light Company.
