Mary-Ann was the nickname given to the first steam turbine used in a public utility to generate electricity in America. Hartford Electric Light Company of Hartford, Connecticut, realized an extra demand for electricity in 1900 and decided in 1901 to purchase this steam turbine generator. The turbine, built by Westinghouse and rated at 1.5 megawatts, ran at Hartford Electric's Pearl Street plant from 1901 to 1905.
