context_page_description: Mechanicville Hydroelectric Plant is a 18.3-acre national historic district located at Mechanicville in Saratoga County, New York. The listing included one contributing building and three contributing structures. The district dates to 1897 and includes notable Queen Anne architecture.
  The district includes the powerhouse, an earth embankment, a concrete non-overflow dam, and a 700-foot-long concrete gravity overflow dam. They were built in 1897–1898 by the Hudson River Power Transmission Company and span the western channel of the Hudson River between the Saratoga County shore and Bluff Island.
  It was listed on the National Register of Historic Places in 1989.
  The station was designed to produce 5000 kilowatts from seven hydraulic turbine-generator units. Extensive renovations starting in 2003 have turned the plant into a working museum.
context_section_description: The project consists of a spillway 900 feet (270 m) feet long, an earth embankment dam about 900 feet (270 m) long and 20 feet (6.1 m) high, and a powerhouse. The powerhouse is 220 feet (67 m) wide and 50 feet (15 m) long, made of reinforced concrete.  The horizontally mounted turbines in upstream water passages drive shafts running through packing boxes on the upstream headwall which is 6-foot (1.8 m) thick concrete. The arrangement of horizontal runners, packing box and generators was patented at the time; the layout of the station was a model for many future projects.
