Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage.
Hydroelectricity is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase by about 3.1% each year for the next 25 years.
The Kaituna River is in the Bay of Plenty region of the North Island of New Zealand. It is the outflow from Lakes Rotorua and Rotoiti, and flows northwards for 45 kilometres (28 mi), emptying into the Bay of Plenty near Te Puke. It was the subject of a claim concerning the effluent flowing down the river from Lake Rotorua, which resulted in movement to a land treatment system.
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.
Folsom Powerhouse State Historic Park is a historical site preserving an 1895 alternating current (AC) hydroelectric power station—one of the first in the United States.
The Barron Gorge Hydroelectric Power Station in Queensland, Australia is an electricity power station commissioned in 1963 with a maximum capacity of 66 megawatts (89,000 hp). It is located in the locality of Barron Gorge in the Wet Tropics World Heritage Area 20 kilometres (12 mi) north-west of Cairns. It replaced an earlier station which was the first underground power station in the country and the first hydroelectric station in Queensland. The power station was refurbished in 2006.
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 2,675 MW (3,587,000 hp).
Kakabeka Generating Station is a hydroelectric facility operated by Ontario Power Generation on the bank of the Kaministiquia River, 2 km (1.2 mi) downstream from Kakabeka Falls in the community of Kakabeka Falls, Ontario, 30 km (19 mi) west of Thunder Bay. The plant provides energy to the city of Thunder Bay and area. The station is one of ten hydroelectric stations in Ontario Power Generation's Northwest Plant Group, and is remotely operated from Thunder Bay.
The Patea Dam is a high compacted earth fill–type hydroelectric dam in New Zealand, constructed between 1979 and 1984.
Okere Falls is a small town located 21 km from Rotorua on SH 33 between Rotorua and Tauranga on the North Island of New Zealand. The town is situated on the shore of the Okere Inlet of Lake Rotoiti, from which the Kaituna River flows north towards the Bay of Plenty.
Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island.
Bullendale is an abandoned mining settlement in Otago, New Zealand. It is the site of New Zealand's first industrial hydro-electric power plant. Located in rugged and remote countryside, it has survived to become of historical significance, and several archaeological surveys have been conducted there.
The Coleridge Power Station is a hydroelectric facility at Lake Coleridge on the Rakaia River in Canterbury, New Zealand. The power station is owned and operated by TrustPower. As of 2012, the station generates 39 megawatts (52,000 hp) of electricity, and annual generation averages 270 gigawatt-hours (970 TJ), following redesign of the station's turbines using Computational Fluid Dynamic modelling.
Horahora Power Station was an early hydroelectric power station on the Waikato River in New Zealand. It was the country’s first large-scale power station, completed in 1913. Initially built to service a gold mine, the power station was expanded to supply a significant part of the North Island. The power station remained in use until was submerged by Lake Karapiro, which was formed to supply the larger Karapiro Power Station.
Atiamuri 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 Taupo and Tokoroa.
Hydroelectric power in the United States is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity. In 2019, hydroelectric power produced 38% of the total renewable electricity, and 6.6% of the total U.S. electricity.
The Cruachan Power Station is a pumped-storage hydroelectric power station in Argyll and Bute, Scotland. The scheme can provide 440 MW of power and has a capacity of 7.1 GWh.
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 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. The Plant was considered by some to be the greatest hydroelectric plant at the time. 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.
The Omanawa Falls Power Station is a run of the river hydroelectric facility on the Omanawa River, in the Bay of Plenty in New Zealand. Built in 1915 to supply electricity to the town of Tauranga, it was the Southern Hemisphere's first underground power station.
