In 1909 Abraham Robison's grist mill was converted into an electric generating station. Two 560 kilowatt generating units were placed into service in 1910. High Falls, along with Honk Falls in Warwarsing, were the principal sources of electric supply for the City of Kingston until 1922. In 1924, Charles Dickerson sold the Honk Falls Power Company to United Hudson Electric Corporation. At High Falls a third unit, rated at 1000 kilowatts, was placed into service in 1926, the same year that United Hudson Electric Corporation became part of Central Hudson Gas & Electric Corporation. The three units at High Falls operated until 1972 when high maintenance costs and the lower cost of fuel oil generation made this plant uneconomic. Reversal of fuel oil costs justified reactivating the site with a new generating station, which was placed into service in December, 1986, with a 3250 kilowatt capacity. This station generates approximately ten million kilowatt-hours per year, which is enough energy to take care of the needs of about 1,600 average homes.
