Acaray River
The Acaray River ( Guarani Akaray) is a river in eastern Paraguay. It is born in the Cordillera de Caaguazú, and is joined by the Yguazú and Itakyry rivers later on. The river flows through the Caaguazú and Alto Paraná Departments, and joins the Paraná River in an area between Ciudad del Este and Hernadarias, which was later modified for the construction of the Acaray Dam. One of its main tributaries is the Yguazú River, which also has its own dam: the Yguazú Dam. See also *List of rivers of Paraguay This is a list of rivers in Paraguay.

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 ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

High-voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Rating
In electrical engineering and mechanical engineering, the power rating of equipment is the highest power input allowed to flow through particular equipment. According to the particular discipline, the term ''power'' may refer to electrical or mechanical power. A power rating can also involve average and maximum power, which may vary depending on the kind of equipment and its application. Power rating limits are usually set as a guideline by the manufacturers, protecting the equipment and simplifying the design of larger systems, by providing a level of operation under which the equipment will not be damaged while allowing for a certain safety margin. Equipment types Dissipative equipment In equipment which primarily dissipate electric power or convert it into mechanical power, such as resistors, and speakers, the power rating given is usually the maximum power that can be safely dissipated by the equipment. The usual reason for this limit is heat, although in certain ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Paraguayan Guaraní
The guaraní (, plural: ''guaraníes''; sign: ₲; code: PYG) is the national currency unit of Paraguay. The guaraní was divided into 100 céntimos but, because of inflation, céntimos are no longer in use. The currency sign is ; if unavailable, "Gs." is used. History The law creating the guaraní was passed on 5 October 1943, and replaced the peso fuerte at a rate of ₲1 = 100 pesos fuertes. Guaraníes were first issued in 1944. Between 1960 and 1985, the guaraní was pegged to the United States dollar at ₲126 = US$1. Coins In 1944, aluminum-bronze coins were introduced in denominations of 1¢, 5¢, 10¢, 25¢ and 50¢. All were round shaped. The obverses featured a flower with "Republica del Paraguay" and the date surrounding it, except for the 50¢, which featured the lion and Liberty cap insignia. The denomination was shown on the reverses. First series: The second issue, introduced in 1953, consisted of 10¢, 15¢, 25¢ and 50¢ coins. All were again minted in ...

List Of Power Stations In Paraguay
Electricity in Paraguay comes almost entirely from hydropower. As Paraguay is landlocked and has no significant natural gas reserves, its citizens often burn firewood which contributes to deforestation. The government imports fuel to use, and state-owned Petróleos Paraguayos (Petropar) has a monopoly on all crude oil and petroleum product sales and imports in Paraguay. It operates Paraguay's sole refinery, the Villa Elisa facility. Oil Paraguay consumed of petroleum in 2006. It does not currently produce any crude oil. In February 2006, Paraguay's Public Works Ministry announced that oil had been discovered in the western Chaco region by British oil company CDS Energy Services, though CDS stated that the reservoir was too tight to facilitate unassisted oil production.Country analysis brief: Paraguay/Urugua ...

Energy Infrastructure Completed In 1981
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 ...
