Question: Which canal supplies a Hydropower plant, Alexandria Canal or Edison Sault Power Canal?
Context: The Raritan Water Power Canal in Raritan, New Jersey was a three-mile long water power canal built during the early 1840s to power industries.  The canal has been determined to be eligible for the National Register.  The canal is included in Duke Island Park, as part of the Somerset County Park System. Shadiwal Hydropower Plant (SHPP) is a small, low-head hydroelectric generation station of 13.5 megawatt generation capacity (two units of 6.75 MW each), located near Gujrat city at Shadiwal 100 kilometer North-West of Lahore, Punjab province of Pakistan, on the flows of Upper Jhelum Canal.  It is a small hydropower generating plant constructed and put in commercial operation on June 1961 with the Average Annual generating capacity of 42.67 million units of least expensive electricity. 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. 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. The Alexandria Canal was a canal in the United States that connected the city of Alexandria to Georgetown in the District of Columbia. Belleville Lake is a 2-square-mile man-made lake located in Wayne County in the U.S. state of Michigan.  It was created in 1925 by the Eastern Michigan Edison Company, by damming the Huron River.  The 28-foot-high dam was the last in a series of five dams along the river, creating electricity from hydropower until 1962.  The hydropower plant was refurbished in 1988 and has a nameplate production of 1.7 MW.  It contains 17,780 acre-feet of water in the seven-mile-long lake.  The small community of Rawsonville was flooded out by the dam. The Blavet river flows from central Brittany and enters the Atlantic Ocean on the south coast near Lorient.  The river is canalised for most of its length, forming one of the links in the Brittany canal system.  It connects with the Canal de Nantes à Brest at Pontivy and runs to Hennebont, a distance of 60 km.  From the last lock at Polvern, the river is tidal and considered as a maritime waterway, giving access to the seaport of Lorient and the Atlantic Ocean.  It became more important when the western half of that system was cut off by the construction of the Guerlédan dam and hydropower plant.  Today, boats coming from Nantes via Redon have to take the Canal du Blavet in order to reach the ocean near Lorient. 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. The Riverside Canal is an irrigation canal in El Paso County beginning southeast of El Paso, Texas.  The canal acquires water from the Riverside Diversion Dam on the Rio Grande 15 mi southeast of El Paso.  The canal is managed by the US Bureau of Reclamation.  The canal extends for 17.2 mi with a capacity of 900 cubic feet per second.  Water from the canal irrigates about 39,000 acres (160 km²).  The canal and diversion dam is the southernmost system on an irrigation project extending along the Rio Grande in New Mexico and Texas.  The canal supplies a canal network extending throughout the Upper Rio Grande Valley. Jabban (Malakand-I) Hydropower Plant (MHPP-I) is a small, low-head, run-of-the-river hydroelectric power generation station of 22 megawatt generation capacity (four units of 5.5 MW each), located at Jabban, Malakand District, KPK province of Pakistan on the flows of Swat River and about 210 km from Pakistan's Capital Islamabad, 45 km from the city of Mardan and 7 km upstream of 20 MW Dargai Hydropower Plant (Malakand-II).  It is a small hydel power generating plant constructed and put in commercial operation on July 1938 generating Average Annual yield of 122 million units (GWh) of least expensive electricity.
