The Shoalhaven Scheme is a dual-purpose water supply and Pumped-storage Hydroelectricity scheme located on the South Coast region of New South Wales, Australia.
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and a capacity factor of 71.9%.
Holtwood Dam is the oldest of three major dams built across the lower Susquehanna River, and the middle location of the three. It was constructed as the McCalls Ferry Dam between 1905 and 1910 by the Pennsylvania Water & Power (PW&P) Company. The dam was renamed Holtwood in honor of two company executives. PW&P merged with Pennsylvania Power & Light (PPL) in 1955. In 2015 Talen Energy took over PPL's generation and immediately sold the Holtwood plant to Brookfield Renewable Energy Partners to comply with federal antitrust requirements.
The York Haven Dam is a low head, run-of-the river, dam and hydroelectric plant that is located on the Susquehanna River in the United States.
The Trevallyn Power Station is a run-of-the-river hydroelectric power station located in the northern Midlands region of Tasmania, Australia. The power station is situated on the Great Lake and South Esk catchment and is owned and operated by Hydro Tasmania.
The Fierza Hydroelectric Power Station is a large hydroelectric power station on the Drin River, in Albania.
Amtrak's 25 Hz traction power system is a traction power network for the southern portion of the Northeast Corridor (NEC), the Keystone Corridor, and several branch lines between New York City and Washington D.C. The system was constructed by the Pennsylvania Railroad between 1915 and 1938 before the North American power transmission grid was fully established. This is the reason the system uses 25 Hz, as opposed to 60 Hz, which is the standard frequency for power transmission in North America. The system is also known as the Southend Electrification, in contrast to Amtrak's 60 Hz traction power system that runs between Boston and New Haven, which is known as the Northend Electrification system.
The Dix Dam is a dam on the Dix River located between Mercer and Garrard County, Kentucky. It was constructed to generate hydroelectricity and prevent flooding of the Kentucky River but is better known for creating Herrington Lake.
Ātiamuri Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is the third of eight hydroelectric power stations on the Waikato River. The station can easily be seen from State Highway 1 between Taupō and Tokoroa.
Whakamaru Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It is the fourth hydroelectric power station on the Waikato River.
Coteau Creek Hydroelectric Station is a hydroelectric station owned by SaskPower, located near Danielson Provincial Park about 100 kilometres (62 mi) south-west of Saskatoon, between the towns of Outlook and Elbow. The station is on the South Saskatchewan River and draws water from the Gardiner Dam and is named after a nearby tributary to the South Saskatchewan River.
Lake Clarke in Pennsylvania is a man-made lake along the Susquehanna River formed by the Safe Harbor Dam, a public works project of the 1930s Great Depression and one of the electrification projects of the New Deal. It is approximately 12 miles (19 km) long centered within the Conejohela Valley approximately 6 miles (9.7 km) downstream of historic Wright's Ferry (1630−1901).
The Conejohela Flats are a group of islands in the flooded Conejohela Valley, a large floodplain along the southernmost 30 miles (50 km) of the Susquehanna River in Pennsylvania and Maryland in the United States. The valley was flooded primarily during the early 1900s by the construction of the Holtwood, Conowingo, and Safe Harbor dams from 1910 to 1931.
Pennsylvania Water & Power was an American company. It was the first power plant in the world to combine a hydroelectric generator and a coal power generator on the same site. John Abbet Walls was president.
Single-phase generator is an alternating current electrical generator that produces a single, continuously alternating voltage. Single-phase generators can be used to generate power in single-phase electric power systems. However, polyphase generators are generally used to deliver power in three-phase distribution system and the current is converted to single-phase near the single-phase loads instead. Therefore, single-phase generators are found in applications that are most often used when the loads being driven are relatively light, and not connected to a three-phase distribution, for instance, portable engine-generators. Larger single-phase generators are also used in special applications such as single-phase traction power for railway electrification systems.
The St. Margaret's Bay Hydroelectric System consists of three hydroelectric power plants and the related lake, dam, and river systems driving them. The system is situated within both Lunenburg County and the Halifax Regional Municipality, beginning approximately 2.5 km (1.6 mi) east of the Head of Saint Margarets Bay and approximately 10 km (6.2 mi) southwest of Hammonds Plains. The system is part of the East Indian River watershed and drains 271 square kilometres (105 sq mi), with water storage provided in Lunenburg County by Mill Lake, Coon Pond, Sandy Lake, Wrights Lake, Big Indian Lake, Five Mile Lake and, at times, an overflow from Pockwock Lake in the Halifax Regional Municipality. The system is owned and operated by Nova Scotia Power Inc.
