NEK EAD
Natsionalna Elektricheska Kompania EAD (NEK) ( bg, Национална електрическа компания ЕАД ; en, National Electricity Company) is a single-owned joint-stock electric company headquartered in Sofia, Bulgaria. Bulgarian Energy Holding is the holder of the capital of NEK. The main company's activities are the generation of electrical energy, purchase and sale of electrical energy, import and export of electrical energy. NEK is the owner of 30 hydro and pumped storage power plants with a total installed capacity of 2713 MW. Most of the hydropower is generated within four hydropower cascades: Belmeken-Sestrimo-Chaira; Batak, Vacha, and Dolna Arda. All are used to cover peak loads, and to regulate the grid system. NEK is a holder of hydro (HPP&PS) generation license, electricity trading license and public power supply license, all issued by SEWRC. NEK, through its branch Dams and Cascades, manages 40 dams and the total capacity of the storage res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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 ...

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. Its catchment area is 761 km2 spanning from an altitude of 2,186 m at the summit of Golyama Syutkya to 452 m at the town of P ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines Radial turbine, radial and Axial flow turbine, axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the Hydraulic head, head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm.

Hydroelectric Power Stations In Bulgaria
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.
