Niagara Mohawk Power Corporation was a utility provider based in New York State that became part of National Grid plc through an acquisition in 2000. After this merger, the Niagara Mohawk brand was phased out in favor of NationalGridUS identifiers (such as National Grid Buffalo), although the corporation's legal name continues to be Niagara Mohawk Power Corporation in its official annual filings.
The company originated in 1929 when 59 entities merged to form Niagara Hudson Power Corporation, which established an Art Deco-designed headquarters in Syracuse by 1932. It functioned as the leading supplier of electricity and natural gas throughout northeastern, central, and western regions of New York State, covering areas including the Capital District, Syracuse, Buffalo, and Niagara Falls.
In 1950, as a result of antitrust rulings mandating territorial adjustments, the firm adopted the name Niagara Mohawk Power Corporation. Between 1950 and 2002, it operated the Rankine Generating Station located in Niagara Falls, Ontario through its subsidiary Canadian Niagara Power, which was divested to Fortis Inc. in 2002.
Niagara Mohawk was responsible for the development of the Nine Mile Point Nuclear Generating Station, with its initial unit completed in 1969 and a subsequent unit finished in 1988. The facility was sold to Constellation Energy in 2001 and is currently jointly owned by Exelon and Électricité de France.
