    en.wikipedia.org/wiki/War_of_the_currents

    The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...

    Grand Rapids Electric Light & Power Company, established in March 1880 by William T. Powers and others, began operation of the world's first commercial central station hydroelectric power plant, Saturday, July 24, 1880, getting power from Wolverine Chair and Furniture Company's water turbine. It operated a 16-light Brush electric dynamo ...

    A sketch of the Pearl Street Station. Pearl Street Station was Thomas Edison's first commercial power plant in the United States. It was located at 255–257 Pearl Street in the Financial District of Manhattan in New York City, just south of Fulton Street on a site measuring 50 by 100 feet (15 by 30 m). [1]

  5. Direct current - Wikipedia

    en.wikipedia.org/wiki/Direct_current

    The term DC is used to refer to power systems that use only one electrical polarity of voltage or current, and to refer to the constant, zero-frequency, or slowly varying local mean value of a voltage or current. [9] For example, the voltage across a DC voltage source is constant as is the current through a direct current source.

    In 1882, the world's first commercial central DC hydroelectric power plant provided power for a paper mill in Appleton, Wisconsin. [10] Just months later the first investor-owned electric utility, Edison Illuminating Company , completed the first fossil fueled electrical power plant in New York City, to compete with hydroelectric power close to ...

    Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.
