Hydraulic energy (worldwide)

[moinsdewatt]

30 GW hydraulic capacity added worldwide in 2012.

Including 51% of this figure for China alone.
See below for details of their 4 largest hydrau projects underway.

China continues its dominance of the global hydropower market

ITH 30GW of 2012GW, a global cumulative hydropower capacity jumped to 1127GW by the year-end, providing an estimated 3524TWh of electricity generation annually.

Thus, this technology is still one of the largest sources of renewable energy sources.
...............

Just over half (51%) of the hydro capacity in 2012 was in China, converting this market into the most active for the year. With the largest installed capacity in the world, accounting 240.7GW of total capacity, the country is continuing its expansion and currently has 61GW under construction.

The most notable Chinese projects underway are:

- Baihetan (13.1GW), which will be the third largest in China when completed and the fourth largest in the world. It is slated for completion in 2019;

- Wudongde and Xiangjiaba (8.7 and 6.4GW, respectively) are located in Jinsha River. Both are scheduled to be finished in 2015; and

- Xiluodu (14GW) located in Yangtze River. This project was stopped by the Chinese government in 2005 due to lack of environmental impact studies, but construction is again underway.


Meantime after the controversies regarding the location of the Belo Monte hydroelectric power plant in the Amazonas Area, Brazil is surging ahead again. Based on projects underway, it will be for 11GW of new capacity in 2015.

In the Romanche valley, the biggest hydroelectric dam in France comes out of the ground

France 3 AlpsPublished 04 / 10 / 2013

In the Romanche valley, it is the largest hydroelectric dam currently built in France. The "Romanche-Gavet project" carried out by EDF will replace the current development, built between the end of the XNUMXth century and the beginning of the XNUMXth century.



Tons and tons of scrap: the armature of the dam is gradually coming out of the ground. It will rise to 14 meters high with four stacks. Earthworks, embankments, it was necessary to stir 200.000 cubic meters of pebble, and to temporarily derive the bed of the river, Romansh, was provisionally derived

A 9-kilometer tunnel has been drilled in the mountain, between the dam upstream, and the hydroelectric power station, downstream. The current produced will be able to supply 250.000 homes. This is 30% more than the 6 existing factories, installed a century ago. They will be destroyed, except one of them, classified as a "historical monument".

Launched in 2010, the work will spread until 2017. They are coupled with important interventions to secure the sites, especially on the cliffs of the valley. Impact studies have also been carried out, particularly on the flora, fauna and the fish population. EDF must indeed comply with very specific rules for the protection of the environment.

Kembs: EDF launches last generation hydroelectric plant

27 October 2016 / Written by: The Writing energeek

Last October, EDF officially commissioned a new hydroelectric facility in Kembs, in the south of the Haut-Rhin, downstream from the port of Basel. An inauguration that follows four years of work that will have required an investment of more than 20 million euros from the electrician tricolor. This latest-generation hydropower facility perfectly illustrates the imperatives that arise from the energy transition: the new electricity generation infrastructure must now be able to meet the energy needs of our country, while preserving the quality of the environment.

Promote the preservation of Rhine ecosystems ...

The Kembs hydropower facility, which was built between 1928 and 1932, is one of the first to be commissioned on the Rhine. It consists of a dam in charge of supplying water to the Grand Canal d'Alsace, on the banks of which are four hydroelectric power stations, including the current Kembs power station, with a power of 160 MW. In 2010, at the time of the renewal of the Kembs concession, EDF engineers are proposing to renovate the entire site thanks to an unprecedented process that combines industrial imperatives (boosting electricity production) and environmental protection (preserving fauna and flora Rhine).

The project aimed in particular at strengthening the performance of the current Kembs hydropower development, while ensuring the restoration of the Alsatian natural environment. As part of EDF's contribution to the National Biodiversity Strategy, the project is designed globally: the design of the industrial project is closely linked to the definition of environmental compensation and support measures.

The first phase of the project was to increase, through a portion of the Grand Canal water, the flow of the Old Rhine at 52 cubic meters of water per second in winter and up to 150 cubic meters per second in summer (so-called reserve flow) in order to adapt it to the living conditions and reproduction of the fauna that resides there. Proposed by EDF, this measure was supplemented by work to compensate for the gravel deficit of the Old Rhine: a dam was destroyed in order to allow controlled erosion of the banks.

... while strengthening Alsatian hydroelectric production

These developments, however, resulted in a significant decrease in the flow of the Grand Canal d'Alsace and, consequently, reduced the volumes of electricity from downstream plants (a deficit estimated at 110 GWh of electricity per year). The construction of the new K plant aims to compensate for this lack: consisting of two turbines with horizontal axes of a unit power of 4,2 MW, it will enable each year to produce 25 GWh of electricity in a manner totally respectful of the environment.

Anxious to ensure the fish farming continuity of the Rhine, EDF's engineers planned, as soon as the K plant was designed, upstream and downstream structures, such as fish and beaver passes. In addition, to power this new renewable production unit, the electrician has proceeded to renaturation of more than 100 hectares of agricultural land on the Rhine Island and, in particular, the refilling of a former branch of the Rhine called Petit Rhine. A restoration project that remains unique in Europe today.

This new generation hydroelectric plant is therefore added to the other production units installed along the Rhine. All of these plants have an installed capacity of 1.450 MW, for an average annual electricity production of 8,5 TWh.

The excellent health of the hydraulic industry

The hydropower sector is Europe's first renewable energy source, clean and from a production process that does not generate carbon dioxide. Last May, because of the heavy rainfall that hit the country, the French hydraulic production reached an annual record of 7.188 GWh, testifying to the excellent health of the sector. In order to support the goal of doubling installed capacity in the field of renewable energies, from 28 GW to more than 50 GW in the French electricity mix by 2030, the government launched last April a tendering for the development of small hydropower plants, the aim being to strengthen and develop new production capacities.

Because of its intrinsic characteristics, hydropower therefore has an important role to play in the energy strategy of our country and in the success of the energy transition. Given the commitment made by our government in the fight against global warming, it seems essential today that industry players demonstrate innovation, to further maximize the exploitation of the hydraulic potential of the world.

it appears that the emissions are 25% higher than we thought.

That does not mean that it's a lot ...

From an energy and climate point of view, dams are therefore positive.

On the other hand, this is not the case for ecology and sediment flows. Indeed, each dam, whether hydroelectric or not, constitutes an obstacle for the circulation of species and sediments (sand, silt ...).

For animal species, particularly migratory species (salmon, eels, etc.), these dams block access to breeding areas and cause the death of many individuals, even when there are fish passes. http://www.futura-sciences.com/planete/ ... rages-910/

On the other hand, unless there is a totalitarian regime, it is highly unlikely that a new book will come to Europe.

I missed your message (Excuse me for this action)

Many dams are sources of problems, because looking from a height> NONE is viable over time
Displacement of populations en masse, destruction of land, a prohibitive cost in any case, deaths of men and animals each time
In the long term, production which is not in phase with the work undertaken, the list of repercussions are often forgotten or even hidden from the general public> China, USA, France, Brazil, Russia, India, Pakistan, Spain, Italy, Germany , Switzerland, etc ....
With a little bit of research, it is possible to see what these achievements are for the term run (energy demand is in exponential mode)
Must surely look differently for the coming generations because these thousands of dams are lands that have disappeared

Some figures in 2012
Throughout the twentieth century, the idea of ​​economic development has been associated with dams. Result: today there are 800 000 in the world of which 52 000 are considered as large dams, that is to say a height of more than 15 meters and with a reservoir greater than 3 millions of m3. The four major dam-building countries account for three quarters: 45% in China, 14% in the United States, 9% in India and 6% in Japan. France owns 569 large dams, or 1% of the world total.
