Mica Dam is a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada. It was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir created by the dam is Kinbasket Lake. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the first 500 kV installation of sulphur hexafluoride (SF6) insulated switchgear in the world.
An underground power station is a type of hydroelectric power station constructed by excavating the major components from rock, rather than the more common surface-based construction methods.
TransAlta Corporation is an electricity power generator and wholesale marketing company headquartered in Calgary, Alberta, Canada. It is a privately owned corporation and its shares are traded publicly. It operates 76 power plants in Canada, the United States, and Australia. TransAlta operates wind, hydro, natural gas, and coal power generation facilities. The company has been recognized for its leadership in sustainability by the Dow Jones Sustainability North America Index, the FTSE4Good Index, and the Jantzi Social Index. TransAlta is Canada's largest investor-owned renewable energy provider. The company is not without controversy as the Alberta Utility Commission ruled in 2015 that TransAlta manipulated the price of electricity when it took outages at its Alberta coal-fired generating units in late 2010 and early 2011.

Stave Lake is a lake and reservoir for the production of hydroelectricity in the Stave River system, located on the northern edge of the District of Mission, about 65 km (40 mi) east of Vancouver, British Columbia, Canada. The main arm of the lake is about 20 km (12 mi) long from north to south and its southwest arm, ending at Stave Falls Dam near Stave Falls, is about 9.5 km (5.9 mi) long. The total area of the lake currently is about 55 square kilometres. Prior to construction of the dam, the lake was about one-third the size of its current main arm.
The Rubicon Hydroelectric Scheme is a small run-of-the-river hydroelectric scheme located on the Rubicon and Royston Rivers, north east of Melbourne, 40 km (25 mi) south-west of Alexandra, Victoria, Australia. The scheme commenced in 1922, and was the first state-owned hydroelectric scheme to generate electricity in mainland Australia, and among the first in the world to be remotely controlled. For the first ten years of its operation it supplied on average 16.9% of electricity generated by the State Electricity Commission of Victoria. It is now owned and operated by AGL Energy and contributes approximately 0.02% of Victoria's energy supply.
The Jordan River Dam, officially the Jordan River Diversion Dam, and known locally simply as Diversion Dam, is a dam located in Jordan River, British Columbia, Canada. It is part of the second hydroelectric development on Vancouver Island.
Hayward Lake is a lake and reservoir on the Stave River in the Lower Mainland of British Columbia, Canada. Located in the District of Mission about 60 km east of Vancouver, Hayward Lake is formed by Ruskin Dam, which lies about 3 km upstream from the Stave River's confluence with the Fraser River at Ruskin, which sits astride the Mission-Maple Ridge boundary. The lake begins at the tailrace from the Stave Falls Dam and is about 7.5 km in length and an average of 0.5 km wide, with a maximum width of 1.5 km when lengths of small inlets are taken into account.
Alouette Lake, originally Lillooet Lake and not to be confused with the lake of that name farther north, is a lake and reservoir in Maple Ridge, British Columbia, Canada. It is located at the southeast foot of the mountain group known as the Golden Ears and is about 16 km in length on a northeast–southwest axis. It and the Alouette River, formerly the Lillooet River, were renamed in 1914 to avoid confusion with the larger river and lake farther north, with "Alouette", the French word for "lark", being chosen as being melodious and reminiscent of the original name in tone.
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.
Spray Lakes Reservoir is a reservoir in Alberta, Canada. The Spray Lakes were a string of lakes formed along the Spray River, a tributary of the Bow River. With the damming of the river, the lakes were united in the Spray Lakes Reservoir.
The Upper Kotmale Dam is located in Talawakele, within the Nuwara Eliya District, in the Central Province of Sri Lanka. The dam feeds the third largest hydroelectric power station in the country.
The Koyna Hydroelectric Project is the second largest hydroelectric power plant in India, just after the Tehri Dam Project. It is a complex project with four dams including the largest dam on the Koyna River, Maharashtra, hence the name Koyna Hydroelectric Project. The project site is in Satara district.
Stave Falls Dam is a dual-dam power complex on the Stave River in Stave Falls, British Columbia, Canada. The dam was completed in 1912 for the primary purpose of hydroelectric power production. To increase the capacity of Stave Lake, the dam was raised in 1925 and the Blind Slough Dam constructed in an adjacent watercourse 500 m (1,600 ft) to the north, which was the site of the eponymous Stave Falls. In 2000, the dam's powerhouse was replaced after a four-year upgrade. The original Stave Falls powerhouse was once British Columbia's largest hydroelectric power source, and is a National Historic Site of Canada.

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.
The Snoqualmie Falls Hydroelectric Plant is located just north of Snoqualmie in King County, Washington state, US. It is situated about 22 mi (35 km) east of Seattle. Located just below the Snoqualmie Falls, the power plant consists of two power houses, Plant 1 and Plant 2. Plant 1 was completed in 1899 and is located underground. It is the first completely underground hydroelectric power plant ever built in the world. Plant 2 was built in 1910 and is located along the right bank of the Snoqualmie River. Both plants receive water from a small reservoir created by a weir atop the falls. Plant 1 has an installed capacity of 13.7 MW and Plant 2 a capacity of 40.2 MW for a total installed capacity of 53.9 MW, enough to power 40,000 homes.
The Kemano Generating Station is situated 75 km (47 mi) southeast of Kitimat in the province of British Columbia, Canada. It was completed in 1954, providing hydroelectricity for Alcan's Kitimat Aluminum smelter. The powerhouse is built in a cavern created 427 m (1,400 ft) inside the base of Mt Dubose. It produces 896 MW of power from its eight generator units, each of which has a capacity of 112 MW. It was the largest producer in the province when it was built, and is now the fifth largest electrical plant in British Columbia.
Wreck Cove is the largest hydroelectric system in Nova Scotia with a generating capacity of 215.8 MW. Constructed from 1975 to 1978, south of the Cape Breton Highlands National Park, Wreck Cove collects drainage water from 216 square kilometres (83 sq mi) of the Cape Breton Highlands plateau to generate renewable electricity. It consists of two generating stations: the Gisborne Generating Station, with an installed capacity of 3.5 MW, and the Wreck Cove Generating Station, with an installed capacity of 212 MW, producing on average 318 GWh annually—enough energy to power about 30,000 homes.
