Batak Hydro Power Plant
Batak Hydro Power Plant () is an active underground hydro power plant located in Batak, Bulgaria, which is a part of the Batak Hydropower Cascade.Спасов, Мире, Електрификацията на България и нейните строители, том 2, (1948 – 2000), Издател Херон Прес, София, 2000, с. 67, ISBN 954-580-079-8 History The idea for the construction of power plants along the Vacha River utilising the catchment area in the Western Rhodopes, dates back to 1920, when engineer Ivan Mavrov proposed it in his work "Archive of Water Power in Bulgaria". This idea was later taken up by engineer Todor Romanov in the 1930s. The conceptual and technical design for the entire "Batak Hydropower Cascade" was developed between 1951 and 1955 in "Hydro Energy Project".Спасов, Мире, Електрификацията на България и нейните строители, том 2, (1948 – 2000), Издател Херон Пр ...

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulg ...

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, 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. Since ancient t ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an Impulse (physics), impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less Energy conversion efficiency, efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled ov ...

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 ...

Hydro 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.

Batak Hydropower Cascade
The Batak Hydroelectric Cascade ( bg, Баташки водносилов път, translit. ''Batashki Vodnosilov Pat'') is situated in the Pazardzhik Province, southern Bulgaria and is among the first hydroelectric cascades in the country. Inaugurated on 6 September 1959, it includes seven reservoirs and three underground hydro power plants — Batak Hydro Power Plant, Batak, Peshtera Hydroelectric Power Station, Peshtera and Aleko Hydro Power Plant, Aleko with a combined installed capacity of 254.2 MW, producing an average of 796 GWh annually. Located in the Rhodope Mountains, the complex receives waters from the drainage basins of the Chepinska reka, Stara reka (Maritsa), Stara reka and Vacha (river), Vacha, right tributaries of the Maritsa, as well as the Dospat (river), Dospat, a left tributary of the Nestos (river), Mesta.

Vacha (river)
The Vacha (, ) is a river in south Bulgaria, one of the main right tributaries of the Maritsa. It is 104 km long and is formed by the confluence of the rivers Buynovska (cirillic: Буйновска река), Trigradska (cirillic: триградска река) and a small unnamed river. Background The Vacha passes through Krichim Dam and Vacha Dam that secure drinking water for Plovdiv and its plains. It runs through the Rhodopes The Rhodopes (; bg, Родопи, ; el, Ροδόπη, ''Rodopi''; tr, Rodoplar) are a mountain range in Southeastern Europe, and the largest by area in Bulgaria, with over 83% of its area in the southern part of the country and the remainder ... forming a deep valley where the two dams are located. An important town in the valley is Devin. It is the second largest river that has its source in the Rhodopes after the Arda. The Vacha does not flow close to any industrial enterprises, which is the reason for its clear water. The origin of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Rhodopes
The Rhodopes (; bg, Родопи, ; el, Ροδόπη, ''Rodopi''; tr, Rodoplar) are a mountain range in Southeastern Europe, and the largest by area in Bulgaria, with over 83% of its area in the southern part of the country and the remainder in Greece. Golyam Perelik is its highest peak at . The mountain range gives its name to the terrestrial ecoregion Rodope montane mixed forests that belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm. The region is particularly notable for its karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge. A significant part of Bulgaria's hydropower resources are located in the western areas of the range. There are a number of hydro-cascades and dams used for electricity production, irrigation, and as tourist destinations. In Greece, there are also the hydroelectric power plants of Thisavros and Platanovrysi. The Rhodopes have a rich cultural heritage ...
