Energy--United States


A chart showing the growth (power rating vs. combined cycle efficiency) of the advanced Westinghouse 501F (W501F) gas turbine from its introductory rating of 150MW in 1988 to 181MW in 1998, at the time of that Siemens acquired Westinghouse's gas turbine operations. This engine was adopted by Siemens as its primary 60Hz offering and renamed the model SGT6-5000F. This chart was used in a Westinghouse Combustion Turbine product line presentation by Keith Johnson around 1998.

Originally called the Westinghouse Electric Company, George Westinghouse (1846-1914) founded his manufacturing company in Pittsburgh, Pennsylvania, on January 8, 1886. In 1889, he renamed his business The Westinghouse Electric and Manufacturing Company. Westinghouse's primary products include turbines, generators, motors and switchgear related to the generation, transmission, and use of electricity. The company changed its name to Westinghouse Electric Corporation in 1945. In 1981, the company began to relocate its division headquarters for the Steam-Turbine Generator Divisions from Pennsylvania (turbines from Lester and generators from Pittsburgh) to Orlando, Florida. The Power Generation Business Unit (PGBU) building was located in The Quadrangle, at 4400 Alafaya Trail. Originally, Westinghouse had purchased a large plot of land for future development that extended westward from Alafaya Trail to Rouse Road. The original headquarters was located on several acres of that land parcel close to Alafaya Trail.

As the PGBU grew in size, other buildings were rented and then, after PGBU was sold to Siemens Corporation, additional buildings were added to the complex. In 1994, after a major corporate management shuffling and commitment to change from an industrial manufacturing company to primarily a broadcasting/communications company, Westinghouse bought the CBS Network and changed its name to the CBS Corporation. As the PGBU grew in size, other buildings were rented and then, after PGBU was sold to Siemens Corporation in 1998, additional buildings were added to the Quadrangle.
