Westinghouse Electric

"1895 – installed hydropower AC generators at Adams Power Plant, Niagara Falls which supplied power to Buffalo, New York, completed 1896"

"Westinghouse Electric was founded by George Westinghouse in Pittsburgh, Pennsylvania in 1886. The firm became active in developing electric infrastructure throughout the United States. The company's largest factories were located in East Pittsburgh Pennsylvania, and Lester, Pennsylvania and in Hamilton, Ontario, where they made turbines, generators, motors, and switch gear for generation, transmission, and use of electricity.  In addition to George Westinghouse, early engineers working for the company included Frank Conrad, Benjamin Garver Lamme, Oliver B. Shallenberger, William Stanley, Nikola Tesla, Stephen Timoshenko and Vladimir Zworykin."

"In 1893, Edward Dean Adams, who headed up the Niagara Falls Cataract Construction Company, sought Tesla's opinion on what system would be best to transmit power generated at the falls. Over several years, there had been a series of proposals and open competitions on how best to use power generated by the falls. Among the systems proposed by several US and European companies were two-phase and three-phase AC, high-voltage DC, and compressed air. Adams pumped Tesla for information about the current state of all the competing systems. Tesla advised Adams that a two-phased system would be the most reliable, and that there was a Westinghouse system to light incandescent bulbs using two-phase alternating current. The company awarded a contract to Westinghouse Electric for building a two-phase AC generating system at the Niagara Falls, based on Tesla's advice and Westinghouse's demonstration at the Columbian Exposition that they could build a complete AC system. At the same time, a further contract was awarded to General Electric to build the AC distribution system."

"At the beginning of 1893, Westinghouse engineer Benjamin Lamme had made great progress developing an efficient version of Tesla's induction motor, and Westinghouse Electric started branding their complete polyphase AC system as the "Tesla Polyphase System". They believed that Tesla's patents gave them patent priority over other AC systems. Westinghouse Electric asked Tesla to participate in the 1893 World's Columbian Exposition in Chicago where the company had a large space in a building devoted to electrical exhibits. Westinghouse Electric won the bid to light the Exposition with alternating current and it was a key event in the history of AC power, as the company demonstrated to the American public the safety, reliability, and efficiency of a fully integrated alternating current system. Tesla showed a series of electrical effects related to alternating current as well as his wireless lighting system, using a demonstration he had previously performed throughout America and Europe; these included using high-voltage, high-frequency alternating current to light a wireless gas-discharge lamp."
