Revin Pumped Storage Power Plant
The Revin Pumped Storage Power Plant is located in northern France, near Revin in the department of Ardennes and the Belgian border. The pumped storage power plant, commissioned in 1976, is owned by Électricité de France (EDF) and has a nameplate capacity of 800 megawatts (MW). Measured by capacity, it is the third largest pumped storage power plant in France. Characteristics Revin Pumped Storage Power Plant was constructed as an underground power station: Four Francis turbines which are used for both generating and pumping with a capacity of 200 MW each are located in a 115 m long, 17 m wide and 16 m high cavern. Four transformers are installed on the surface to connect the generators (13 kV) to the electrical grid (400 kV). There are three reservoirs which are connected to the Revin Pumped Storage Power Plant. The upper and lower reservoirs are separated by a vertical distance of 250 m.

Électricité De France
Électricité de France S.A. (literally ''Electricity of France''), commonly known as EDF, is a French multinational electric utility company, largely owned by the French state. Headquartered in Paris, with €71.2 billion in revenues in 2016, EDF operates a diverse portfolio of at least 120 gigawatts of generation capacity in Europe, South America, North America, Asia, the Middle East, and Africa. In 2009, EDF was the world's largest producer of electricity. Its 56 active nuclear reactors (in France) are spread out over 18 sites (nuclear power plants). They comprise 32 reactors of 900 MWe, 20 reactors of 1,300 MWe, and 4 reactors of 1,450 MWe, all PWRs. EDF was created on 8 April 1946 by the 1945 parliament, from the merging of various divided actors. EDF led France's post-war energy growth, with a unique focus on civil nuclear energy, through reconstruction and further industrialization within the Trente Glorieuse, being a fleuron of France's new industrial landscape ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution.

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underground Power Station
An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods. One or more conditions impact whether a power station is constructed underground. The terrain or geology around a dam is taken into consideration, as gorges or steep valleys may not accommodate a surface power station. A power station within bedrock may be less expensive to construct than a surface power station on loose soil. Avalanche-prone valleys often make a surface station unfeasible as well. After World War II, large hydroelectric power stations were placed underground more often in order to protect them from airstrikes. Often underground power stations form part of pumped storage hydroelectricity schemes, whose basic function is to level load: they use cheap or surplus off-peak power to pump water from a lower lake to an upper lake.

Francis Turbine
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 d ...

Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Equalizing Basin
An equalizing basin (german: Ausgleichsbecken) or equalizing reservoir regulates the flow of water below an intermittently operated hydropower station or peaking power plant. This could be a part-load power station (''Teillast-Durchfluss-Kraftwerk'') or a storage power station. Also called a balancing reservoir. Function The hydropower station sited above the basin works only a few hours a day. Often it is only used to generate peak current electricity. During hours of low current demand, the power station switches off in order to save the water available in the headstream for the valuable peak power times. Without some form of equalization, however, the tailwaters would run dry when the turbines shut down. This would result in extremely low levels of water, causing serious problems for the plants and animals that live in and around the stream or river. In general, therefore, the power station operator today is required to regulate the flow in order to ensure a specified mi ...

Renewable Energy In France
Under its commitment to the EU renewable energy directive of 2009, France has a target of producing 23% of its total energy needs from renewable energy by 2020. This figure breaks down to renewable energy providing 33% of energy used in the heating and cooling sector, 27% of the electricity sector and 10.5% in the transport sector. By the end of 2014, 14.3% of France's total energy requirements came from renewable energy, a rise from 9.6% in 2005. The outlook for renewable electricity in France received a boost following the publication in October 2016 of the "Programmation pluriannuelle de l'énergie", showing a commitment to re-balancing the electricity mix towards renewables. According to the report, renewable electricity capacity is planned to grow from 41 GW in 2014 to between 71 and 78 GW by 2023. Historically the electricity sector in France has been dominated by the country's longstanding commitment to nuclear power. However, the report emphasizes that by 2025 ...
