Pļaviņas Hydroelectric Power Station
The Pļaviņas Hydroelectric Power Station has the largest hydroelectric power plant in the Baltics and one of the biggest in the European Union. It is located in Aizkraukle on the Daugava River. It has ten individual water turbines with an installed total capacity of 894 MW. The construction aroused an unusual wave of protest in 1958. Most Latvians opposed the flooding of historical sites and a particularly scenic gorge with rare plants and natural features, such as the Staburags. The construction of the dam was endorsed in 1959, however, after the purge of relatively liberal and nationally oriented leaders under Eduards Berklavs and their replacement by Moscow-oriented, ideologically conservative cadres led by Arvīds Pelše. The plant was put into full operation in 1968. In 1991–2001, six additional turbines were added to the original four, thus increasing the capacity to 868.5MW. Reconstruction and overhaul of the units between 2007 and 2010 increased both the effic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aizkraukle
Aizkraukle (german: Ascheraden) is a town in Vidzeme region in Latvia, the administrative centre of Aizkraukle Municipality on the right bank of the Daugava River. The population in 2020 was 7,018.

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Hydroelectric Power Plant
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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.

Baltics
The Baltic states, et, Balti riigid or the Baltic countries is a geopolitical term, which currently is used to group three countries: Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics. All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation. The term "Baltic states" ("countries", "nations", or similar) cannot be used unambiguously in the context of cultural areas, national identity, or language. While the majority of ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...

Eduards Berklavs
Eduards Berklavs (June 15, 1914 – November 25, 2004) was a Soviet and Latvian politician. Eduards Berklavs was born in Kurmāle Parish, today part of the Kuldīga Municipality. During his youth, he was active in labour and communist organizations. In 1930s, he was arrested and served a prison sentence for his communist activities. After Latvia was occupied by the Soviet Union in 1940, Berklavs, with a background as a Komsomol and Communist Party official, rose to become the deputy chairman of the Council of Ministers of Latvian SSR in 1950s. In this position, he opposed the Soviet policies of Russification, supported a larger role for Latvian language and proposed to limit immigration from other parts of the Soviet Union to Latvia. This led to him being labelled as Latvian nationalist and deposed from his position in 1959. He later wrote the Letter of 17 Latvian communists, where he accused the Soviet government of "Great Russian chauvinism" and the "forced assimilation". In ...
