The Ames Hydroelectric Generating Plant, constructed in 1890 near Ophir, Colorado, was one of the first commercial system to produce and transmit alternating current (AC) electricity for industrial use and one of the first AC hydro-electric plants ever constructed. It became operational in 1891 and was built by Westinghouse Electric around two of their large alternators. One was set up in the valley as a generator and driven by water. It was connected by a 2.6-mile (4.2 km) transmission line to the second alternator used as a motor up at the Gold King Mine to drive the mining operation. The facility has been changed and upgraded over the years but is still in operation. It is now on the List of IEEE Milestones.
Croton Dam is an earth-filled embankment dam and powerplant complex on the Muskegon River in Croton Township, Newaygo County, Michigan. It was built in 1907 under the direction of William D. Fargo by the Grand Rapids - Muskegon Power Company, a predecessor of Consumers Energy. The 40-foot-high (12 m) dam impounds 7.2 billion U.S. gallons (6 billion imp. gal/27 billion L) of water in its 1,209-acre (489 ha) reservoir and is capable of producing 8,850 kilowatts at peak outflow. It was listed on the National Register of Historic Places in 1979.
The Oak Grove Hydroelectric Project is a 44 megawatt hydroelectric plant operated by Portland General Electric (PGE) on the Oak Grove Fork Clackamas River. Water for this project is held by three lakes, built between 1923 and 1956. The dam creates the impoundment Lake Harriet.
Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity in the United States. In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity.
Ohio Falls Station is a hydroelectric power station owned by Louisville Gas & Electric (LG&E) and Kentucky Utilities (KU) which is located three miles west of Downtown Louisville, Kentucky. The generating station is located on Shippingport Island at the site of the McAlpine Dam and locks along the Ohio River in Kentucky. The plant was built in 1923 by Byllesby Engineering and Management Corporation and the U.S. Army Corps of Engineers. The plant featured eight 10.4 MW units operating at roughly 13,500 hp per unit. Each unit was composed of Allis Chamber turbines and General Electric generators. The plant is located inside the Ohio Natural Wildlife Conservation Area and is considered a large impoundment hydro power plant. The station was built after a canal and dam within the Ohio river in an attempt to allow boats to navigate the 8 ft vertical drop among the falls that spanned 2 miles wide. Production of the canal and dam began in 1825. It was not until a repair on the dam was needed that Louisville engineers had the idea of building a hydroelectric station to harvest the power of the falls.
The Uglich Hydroelectric Station or Uglich GES is a hydroelectric station on the Volga River in Uglich in Yaroslavl Oblast, Russia, and is the first of the Volga-Kama Cascade of dams.

The Schoellkopf Power Station was built on land owned by Jacob F. Schoellkopf above the Niagara Gorge near the American Falls, 1,600 feet (490 m) downriver from Rainbow Bridge. Understanding the growing need for electricity and the role of harnessing the Falls, Schoellkopf purchased the land for the hydraulic canal on May 1, 1877 for $71,000. After Schoellkopf Sr.'s death in 1903, his sons took over the operation of the power business. In 1918, Schoellkopf's Niagara Falls Hydraulic Power and Manufacturing Company merged with the Niagara Falls Power Company, which was owned by Edward Dean Adams. Much of the site is, as of 2014, occupied by the Maid of the Mist tour boat company as a maintenance area and off-season boat storage yard. The power station remains form a part of a fully accessible tourist attraction associated with Niagara Falls State Park and is connected with its Niagara Gorge hiking trail system.
Kholombidzo Dam, also Kholombidzo Hydroelectric Power Station is a planned 200 megawatts (270,000 hp) hydroelectric dam in Malawi.
St. Anthony Falls in Minneapolis, Minnesota, is the only natural falls on the Mississippi River. Since almost the beginning of settlement in the area by European descendants, the St. Anthony Falls have been used for waterpower. The first allowed settlers were at Ft. Snelling, where construction began in 1820. A sawmill was operating 1821 and a flour mill in 1823. As soon as the land at the sides of the falls became available it was purchased with the intent of using the waterpower of the falls. First lumber mills covered the falls, cutting lumber floated down the Mississippi. After 1870 flour mills started to dominate the area. From 1880 to 1930 the area was the number one flour producer in the US. In later years, some of the power came from steam, but in 1923 half of the waterpower used was for flour milling. Other industries have also used the waterpower.
The Blue Heron Paper Company was a paper mill at Willamette Falls in Oregon City, Oregon, on the southeast bank of the river across from the Willamette Falls Paper Company, the T.W. Sullivan hydroelectric plant, and the Willamette Falls Locks and canal.
