Installed capacity in the context of "Electric generator"

Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity.

Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development.

The Three Gorges Dam, officially known as Yangtze River Three Gorges Water Conservancy Project is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The world's largest power station by installed capacity (22,500 MW), the Three Gorges Dam generates 95±20 TWh of electricity per year on average, depending on the amount of precipitation in the river basin. After the monsoons of 2020, the dam produced nearly 112 TWh in a year, breaking the record of 103 TWh set by the Itaipu Dam in 2016.

The dam's body, 185 meters high and 2,309 meters wide, was completed in 2006. The power plant became fully operational in 2012, when the last of the 32 main water turbines in the underground plant began production. The last major component of the project, the ship lift, was completed in 2015.

Bełchatów Power Station is a coal-fired power station near Bełchatów, Poland. It is Europe's largest coal-fired power station as well as the most toxic one. The power station is owned and operated by PGE GiEK Oddział Elektrownia Bełchatów, a subsidiary of Polska Grupa Energetyczna.

In 2011, a new 858 MW unit was commissioned. increasing the station's total capacity to 5,053 MW. The new unit has an efficiency rating of approximately 42%, contributed to reduction of both fuel consumption and emissions compared to the older units. The unit has been built by Alstom. Alstom also has modernized the low pressure parts in all 12 turbines and, in 2009, PGE and Alstom signed a contract to modernise unit 6. After modernization of other units, the total installed capacity reached 5,420 MW in 2015. In 2017, the electrical capacity of Elektrownia Bełchatow was increased to 5,472 MW. The plant's current achievable capacity is 5,102 MW. In the second half of 2019, the achievable capacity was reduced due to the decommissioning of the oldest unit (unit No 1).
