Constructed to store and service cars and to power the Metropolitan Railway Company’s pioneering Fulton Park line in 1890. Getting fuel and water to the plant was always a problem, and much of the electrical machinery was moved to the consolidated Inman–Poulsen Power House in 1897. The property is mentioned as “the power-house at Fulton Park and plant” in the November 1900 transfer of the Second-street line from the Metropolitan Railway to the City & Suburban, so it seems that the building lasted at least that long, if not the contents.
