Le Pouget (power Station)
Le Pouget is a hydroelectric power station located at Le Truel, on the River Tarn, in the department of Aveyron in France. It uses the difference in height between the artificial lakes of Villefranche-de-Panat and Pareloup on the Lévézou plateau and the river 500 m below. It ranks as the 16th largest station in France. It is part of the complex system that connects the rivers Alrance, Ceor, Viaur, Bage and Violou with the Tarn. In addition to its 440 MW generating capacity it houses a small pumping station that can return 6.6 m³/s of water from the Tarn to its header reservoir. Geography The catchment of this system is on the Lévézou plateau- which is at the western end of the Grandes Causses. The plateau lies between 700 m and 900 m and consist of granite rocks. It is a landscape of gentle valleys, drained to the north by the Ceor, Viaur, Bage and Violou which flow towards Rodez, and to the south by the Alrance and the Ruisseau de Asseynes which fall steeply into the Tarn ...

Tarn (river)
The Tarn (; oc, Tarn, la, Tarnis, possibly meaning 'rapid' or 'walled in') is a long river in the administrative region of Occitania in southern France. It is a right tributary of the Garonne. The Tarn runs in a roughly westerly direction, from its source at an elevation of on Mont Lozère in the Cévennes mountains (part of the Massif Central), through the deep gorges and canyons of the Gorges du Tarn that cuts through the Causse du Larzac, to Moissac in Tarn-et-Garonne, where it joins the Garonne, downstream from the centre of town. Its basin covers approximately , and it has a mean flow of approximately . The Millau Viaduct spans the valley of the Tarn near Millau, and is now one of the area's most popular attractions. Main tributaries The tributaries of the Tarn include: * Agout (in Saint-Sulpice) * Alrance * Aveyron (near Montauban) * Cernon * Dourbie (in Millau) * Dourdou de Camarès * Jonte (in Le Rozier) * Lemboulas * Lumensonesque * Muze * Rance (near Tréb ...

Pinet (power Station)
Pinet is a dam and hydroelectric power station on the River Tarn in Saint-Victor-et-Melvieu in Aveyron, southern France. The dam was built in 1932, and the station has five Francis turbines generating 42.5MW. The dam is long and high. Description The dam The dam constructed in 1929 was regulated by 18 groups of sluices. These were replaced by three rising barriers, in dimension. These gave the dam capacity to cope with floods of up to . The lake The dam raises the level of the Tarn by and the lake formed, the Lac de Pinet, is at an altitude of and has a surface area is It lies in the communes of Saint-Rome-de-Tarn, Viala-du-Tarn and Saint-Victor-et-Melvieu.

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] |
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 ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an 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 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 overland to take part in the California Gold Rush. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ségala (Midi-Pyrénees)
The Ségala (; oc, Segalar) is a geographical region that straddles the border between the departments of Aveyron and Tarn, in the Occitanie region of southern France. It is known as the land of a hundred valleys- and traditionally grew the grain for all of Aveyron. Geography The Ségala is deeply valleyed region lying between 200 m and 800 m between the valley of the Viaur and the valley of the Aveyron. The valleys are deep and wooded, while the summits and the plateau are dominated by pasture land used for the raising of high-quality beef. Geology The underlying rocks are schists which leads to acid soils. The soils are light and thin, and were unproductive before the opening of the railway with the Viaduc du Viaur, which allowed lime to be brought in. Liming neutralised the soil opening it up to agriculture.
