Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
Renewable energy in Portugal was the source for 25.7% of total energy consumption in 2013. In 2014, 27% of Portugal's energy needs were supplied by renewable sources. In 2016, 28% of final energy consumption in Portugal came from renewable sources.
India is 5th globally for installed hydroelectric power capacity. As of 31 March 2020, India's installed utility-scale hydroelectric capacity was 46,000 MW, or 12.3% of its total utility power generation capacity. Additional smaller hydroelectric power units with a total capacity of 4,683 MW have been installed. India's hydroelectric power potential is estimated at 148,700 MW at 60% load factor. In the fiscal year 2019–20, the total hydroelectric power generated in India was 156 TWh with an average capacity factor of 38.71%.
The Silin Dam is a concrete gravity dam on the Wu River in Sinan County, Guizhou Province, China. The dam has an associated hydroelectric power plant with a 1,080 MW capacity utilizing 4 x 270 MW Francis turbine-generators. The dam is 310 m (1,017 ft) long, 117 m (384 ft) high and composed of roller-compacted concrete. Its reservoir has a 1,205,000,000 m3 (976,909 acre⋅ft) capacity, 184,000,000 m3 (149,171 acre⋅ft) of which is flood storage. The dam also supports ship lift. Construction on the dam began in October 2004, the dam began to impound the river in March 2008 and by May 2009, the power plant's first generator was operational. The remaining generators were operational by December 2009.
The Minghu Dam (Chinese: 明湖水壩; pinyin: Mínghú Shuǐbà, renamed the Takuan Dam, is a concrete gravity dam on the Shuili River located 7 km north of Shuili Township in Nantou County, Taiwan. The reservoir formed by the dam serves as the lower reservoir for the Minhu Pumped Storage Hydro Power Station. Sun Moon Lake serves as the upper reservoir.
The Edolo Pumped Storage Plant is located along the Oglio River just downstream of Edolo, Brescia Province in the Lombardy region of Italy. Using the pumped-storage hydroelectric method, it has an installed capacity of 1,000 megawatts (1,300,000 hp). Its generators were commissioned between April 1984 and November 1985. Lake Avio was previously completed in 1929 and Lake Benedetto completed in 1940.
As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also four pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
Hydroelectricity is the second most important renewable energy source after solar energy in Japan with an installed capacity of 50.0 gigawatt (GW) as of 2019. According to the International Hydropower Association Japan was the world's sixth largest producer of hydroelectricity in 2020. Most of Japanese hydroelectric power plants are pumped-storage plants. Conventional hydropower plants account for about 20 GW out of the total installed capacity as of 2007.
Aguieira Dam is a multiple-arch dam on the Mondego River, located on border line between the municipalities of Mortágua and Penacova, in Central Portugal.
Salamonde Dam is a concrete arch dam on the Cávado River, where the river forms the border line between the districts of Braga and Vila Real. It is located in the municipality Vieira do Minho, in Braga District, Portugal.
Hydroelectricity is currently China's largest renewable energy source and the second overall after coal. According to the International Hydropower Association, China is the worlds largest producer of hydroelectricity as of 2021. China's installed hydroelectric capacity in 2021 was 390.9 GW, including 36.4 GW of pumped storage hydroelectricity capacity, up from 233 GW in 2011. That year, hydropower generated 1,300 TWh of power, an increase of 68 TWh over 2018 when hydropower generated 1,232 TWh of power, accounting for roughly 18% of China's total electricity generation.
In 2008, Net electricity use in Portugal was 51.2 TWh. Portugal imported 9 TWh electricity in 2008. Population was 10.6 million.
Achwa 2 Hydroelectric Power Station is a 41 megawatts (55,000 hp) hydroelectric power plant, in Uganda.
