“Pearl Street Station was the first commercial central power plant in the United States. It was located at 255–257 Pearl Street in the Financial District of Manhattan, New York City, just south of Fulton Street on a site measuring 50 by 100 feet (15 by 30 m). The station was built by the Edison Illuminating Company, under the direction of Francis Upton, hired by Thomas Edison. Pearl Street Station was fired by coal; it began with six dynamos, and it started generating electricity on September 4, 1882, serving an initial load of 400 lamps at 82 customers. By 1884, Pearl Street Station was serving 508 customers with 10,164 lamps. The station was originally powered by custom-made Porter-Allen high-speed steam engines designed to provide 175 horsepower at 700 rpm, but these proved to be unreliable with their sensitive governors. They were removed and replaced with new engines from Armington & Sims that proved to be much more suitable for Edison's dynamos. Pearl Street Station was also the world's first cogeneration plant. While the steam engines provided grid electricity, Edison made use of the thermal byproduct by providing steam heating to local manufacturers and nearby buildings on the same Manhattan block.” (Pearl Street Station, Wikipedia)
