Djibloho Dam
The Djibloho Dam is a gravity dam on the Wele River near Djibloho in Wele-Nzas, Equatorial Guinea. The primary purpose of the dam is hydroelectric power generation and it supports a power station. Construction on the project began in 2008 and it was inaugurated in October 2012. It is the largest hydroelectric power station in the country. Most of the project's cost was funded by the host government but some funds were provided by the Chinese government. Sinohydro Sinohydro ( Chinese: 中国水电; long form: 中国水利水电建设集团公司) is a Chinese state-owned hydropower engineering and construction company. In the 2012 Engineering News-Record Top 225 Global Contractors, a ranking by annual rev ... constructed the dam and power station.

Equatorial Guinea
Equatorial Guinea ( es, Guinea Ecuatorial; french: Guinée équatoriale; pt, Guiné Equatorial), officially the Republic of Equatorial Guinea ( es, link=no, República de Guinea Ecuatorial, french: link=no, République de Guinée équatoriale, pt, link=no, República da Guiné Equatorial), *french: link=no, République de Guinée équatoriale * pt, link=no, República da Guiné Equatorial is a country on the west coast of Central Africa, with an area of . Formerly the colony of Spanish Guinea, its post-independence name evokes its location near both the Equator and the Gulf of Guinea. , the country had a population of 1,468,777. Equatorial Guinea consists of two parts, an insular and a mainland region. The insular region consists of the islands of Bioko (formerly ''Fernando Pó'') in the Gulf of Guinea and Annobón, a small volcanic island which is the only part of the country south of the equator. Bioko Island is the northernmost part of Equatorial Guinea and is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wele-Nzas
Wele-Nzas Province is a province in the eastern portion of continental Equatorial Guinea. Its capital is Mongomo. It borders the Equatoguinean provinces of Centro Sur to the west and Kié-Ntem to the north, with Gabon's Woleu-Ntem Province to the east and south. As of 2015, the population of Wele-Nzas was 192,017. It derives its name from the Benito River (also called the ''Wele'') and the Piedra Nzas mountain range. History The earliest settlers of Wele-Nzas, and the only inhabitants of the region for nearly 15,000 years, were the Byele peoples. Bantu migration ultimately displaced the Byele, and during the 20th century the last of the Byele migrated to Cameroon. The Fang people ultimately became the predominant ethnic group in the province. As European explorers mostly avoided the interior of Equatorial Guinea, there are few accounts of the region in early European histories; even the Spanish governors of the region did not visit Wele-Nzas until the official formation of Spani ...

Francis-type
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and 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 head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for diff ...

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Djibloho
Djibloho, officially the ''Administrative City of Djibloho'', (Spanish: ''Ciudad administrativa de Djibloho'') is the newest province of Equatorial Guinea, formally established by law in 2017. The administrative city was initially carved out of Añisok, a district in Wele-Nzas, on 1 August 2015, and was created to eventually replace Malabo as Equatorial Guinea's future national capital. Administration Djibloho comprises two urban districts, Ciudad de la Paz and Mbere. The capital is Ciudad de la Paz ("City of Peace"), known as Oyala until 2017. In the 2017 national parliamentary election, Djibloho elected one senator and one deputy Deputy or depute may refer to: * Steward (office) * Khalifa, an Arabic title that can signify "deputy" * Deputy (legislator), a legislator in many countries and regions, including: ** A member of a Chamber of Deputies, for example in Italy, Spai ....

Hydroelectric
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.

Dams Completed In 2012
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2012
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...
