Question: Which canal supplies a Hydropower plant, Alexandria Canal or Edison Sault Power Canal?

full_context: Document 1: Augusta Canal: The Augusta Canal is a historic canal located in Augusta, Georgia, United States. The canal is fed by the Savannah River and passes through three levels (approximately 13 miles total) in suburban and urban Augusta before the water returns to the river at various locations. It was devised to harness the water power at the fall line of the Savannah River to drive mills, to provide transportation of goods, and to provide a municipal water supply. It is the only canal in the US in continuous use for its original purposes of providing power, transport and municipal water.
Document 2: Portage Canal: The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic.
Document 3: Nooksack Falls Hydroelectric Power Plant: The 1500 kilowatt capacity Nooksack Falls Hydroelectric Power Plant was constructed at Nooksack Falls on the Nooksack River in 1906 by Stone & Webster, which is the second oldest operating facility in western Washington. The plant operated for over 90 years and ceased operation in 1997 due to a fire which destroyed the generator. The generator was replaced in 2003 and the plant resumed operations.
Document 4: Celilo Canal: Celilo Canal was a canal connecting two points of the Columbia River between the states of Oregon and Washington, U.S. just east of The Dalles.
Document 5: Black Eagle Dam: Black Eagle Dam is a hydroelectric gravity weir dam located on the Missouri River in the city of Great Falls, Montana. The first dam on the site, built and opened in 1890, was a timber-and-rock crib dam. This structure was the first hydroelectric dam built in Montana and the first built on the Missouri River. The dam helped give the city of Great Falls the nickname "The Electric City." A second dam, built of concrete in 1926 and opened in 1927, replaced the first dam, which was not removed and lies submerged in the reservoir. Almost unchanged since 1926, the dam is 782 ft long and 34.5 ft high, and its powerhouse contains three turbines capable of generating seven megawatts (MW) of power each. The maximum power output of the dam is 18 MW. Montana Power Company built the second dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014. The reservoir behind the dam has no official name, but was called the Long Pool for many years. The reservoir is about 2 mi long, and has a storage capacity of 1,710 acre.ft to 1,820 acre.ft of water.
Document 6: Edison Sault Power Canal: The Edison Sault Power Canal supplies the Saint Marys Falls Hydropower Plant, a Cloverland Electric Cooperative hydroelectric plant, in Sault Ste. Marie, Michigan. Excavation of the power canal began in September 1898 and was completed in June 1902. The canal and hydroelectric complex were named a Historic Civil Engineering Landmark in 1983.
Document 7: Power canal: A Power Canal refers to a canal used for hydraulic power generation, rather than for transport of watercraft. The power canal was a major factor in the Industrial revolution in New England in the 19th century. Most early power canals were mill races used mechanically to transfer power directly from falling water to machinery in mill buildings. Later, the hydraulic power generated electricity locally for the same mill factories. These power canals were often filled in as electricity (transported by power lines) replaced the need for local water power, and road transport needs or city expansion needs reclaimed the land. Some hydraulic power canals were transformed into local electric generators, but most were closed. Remains of power canals can be seen in old mill towns and are often protected as historical structures today.
Document 8: James River and Kanawha Canal: The James River and Kanawha Canal was a partially built canal in Virginia intended to facilitate shipments of passengers and freight by water between the western counties of Virginia and the coast. Ultimately its towpath became the roadbed for a rail line following the same course.
Document 9: Alexandria Canal (Virginia): The Alexandria Canal was a canal in the United States that connected the city of Alexandria to Georgetown in the District of Columbia.
Document 10: Aqueduct Bridge (Potomac River): The Aqueduct Bridge (also called the Alexandria Aqueduct) was a bridge between Georgetown, Washington, D.C., and Rosslyn, Virginia. It was built to transport cargo-carrying boats on the Chesapeake and Ohio Canal in Georgetown across the Potomac River to the Alexandria Canal. The same eight piers supported two different bridges: a wooden canal bridge (a wooden roadway bridge was added on top of the canal later) and an iron truss bridge carrying a roadway and an electric trolley line. The bridge was closed in 1923 after the construction of the nearby Key Bridge. The shuttered Aqueduct Bridge was demolished in 1933.
Document 11: Sir Adam Beck Hydroelectric Generating Stations: Sir Adam Beck Hydroelectric Generating Stations are two hydroelectric generating stations in Niagara Falls, Ontario, Canada. Sir Adam Beck Generating Station I, Sir Adam Beck Generating Station II and the Sir Adam Beck Pump Generating Station are all owned by Ontario Power Generation. Following the development of several smaller generating stations around Niagara Falls in the late 19th and early 20th centuries, the Province of Ontario authorized the construction of first major publicly owned generating station in the province. At the time it was built, it was the largest hydroelectric generating station in the world.
Document 12: Belle River Power Plant: Belle River Power Plant is a major coal- and natural gas-fired power plant owned by Detroit Edison, a subsidiary of DTE Energy. It is located in St. Clair County, Michigan, on the peninsula formed by the St. Clair and Belle rivers. The plant was built across M-29 from the St. Clair Power Plant in East China, Michigan, and shares the coal delivery terminal with it. The Belle River plant shares cooling water from the St. Clair River with its sister plant. Five oil-fueled internal combustion generators (named IC1, IC2, 3, 4, and 5) were built in 1981, with the total output 13.75 megawatt. Coal-fired unit 1 of the Belle River plant was completed in 1984, followed by a similar unit 2 in 1985. Each unit has a nameplate capacity of 697.5 MWe, however the coal-fired plant as a whole generates 1260 MWe all year around. In 1999, three peaker natural-gas fired turbines (named 12-1, 12-2, and 13-1) were added, with the total name-plate capacity of 256 MWe.
Document 13: Washington City Canal: The Washington City Canal operated from 1815 until the mid-1850s in Washington, D.C. The canal connected the Anacostia River, called the "Eastern Branch" at that time, to Tiber Creek, the Potomac River, and later the Chesapeake and Ohio Canal (C&O). The canal fell into disuse in the late 19th century and the city government covered over or filled in various sections.
Document 14: St. Clair Power Plant: The Saint Clair Power Plant is a major coal- and oil-fired power plant owned by Detroit Edison, a subsidiary of DTE Energy. It is located in St. Clair County, Michigan, on the west bank of St. Clair River. The plant is across M-29 from the newer Belle River Power Plant in East China, Michigan. The first four units of St. Clair were built in 1953–1954. Since then, three more generating units have been added to the plant. The St. Clair Power Plant generates 1982 megawatts in total. It is Detroit Edison's second largest power producer. The power plant has a large impact on the local economy, employing about 300 workers.
Document 15: Lowell Power Canal System and Pawtucket Gatehouse: The Lowell Power Canal System is the largest power canal system in the United States, at 5.6 miles in length. The system's estimated output is 10,000 horsepower, operating six major canals on two levels, controlled by numerous gates. The system was begun in the 1790s, beginning its life as a transportation canal called the Pawtucket Canal, which was constructed to get logs from New Hampshire down the Merrimack River to shipbuilding centers at Newburyport, Massachusetts, bypassing the 30-plus-foot drop of the Pawtucket Falls.
