Niagara Falls

In 1896, the first long-distance transmission of hydroelectricity from the Niagara Falls Power Company flowed to Buffalo, N.Y., 26 miles away. Although some small-scale use of the water power of the Niagara Falls occurred earlier, this company made the first large-scale utilization for commercial purposes on 26 Aug 1895, when it began supplying power to an aluminium production plant. The power company originated 31 Mar 1886 (though incorporated under a different name). Ground was broken on 4 Oct 1890. By 24 Oct 1893, a contract had been made with the Westinghouse Electric and Mfg. Co. for three 5,000 h.p. generators (two-phase 2,200 volts at 25 cycles/sec). The first 5,000 h.p. turboalternator unit was completed within 18 months.
