A monster! Glad that EDF does something other than nuclear side innovations!

What nominal power? What is the average annual charge? And what price per kWh installed all inclusive?

Otherwise I note that the designs of tidal turbines are radically different from one machine to another ... which shows that the technology is still "looking" ...

Because generally when a technology is developed, all models, from all manufacturers, look alike ... (at least from "far")

on the dip barge


Brittany: the second tidal stream of the Paimpol-Bréhat EDF site has been submerged

The second tidal stream DCNS EDF tidal park was launched Sunday off Ploubazlanec (Côtes d'Armor). Its immersion took place successfully, in less than an hour thanks to a dedicated barge which allows to deposit the tidal turbine on the seabed.

No more specific technical information ... we just have nominal powers ...

I note the:

designed and manufactured by General Electric


I withdraw the:

Glad that EDF does something other than nuclear side innovations!

Public inquiry for tidal turbines off Cherbourg

AFP the 18 August 2016

Two "pilot" tidal turbine farm projects off the northwestern tip of Cotentin have been the subject of public inquiries since Thursday and for a month, we learned from the Manche prefecture. Tidal turbines are underwater turbines that produce electricity with the energy of currents. The two projects are planned in the very strong currents of the Raz Blanchard.


Led by EDF, with DCNS, "Normandie Hydro" provides for 7 tidal turbines of 16 meters in diameter, 3,5 km from Goury (Manche), about thirty meters deep, on a surface of 28 hectares, indicated to the 'AFP one of the investigating commissioners at the town hall of Jobourg, one of the six municipalities concerned by the public inquiry. The other, called "Nepthyd" led by Engie with Alstom, provides for 4 tidal turbines 18 meters in diameter over 17 ha, not far from "Normandie Hydro".

EDF hopes to start work in 2017 and Engie in 2018, according to the commissioner. Industrialists estimate at approximately two years the duration of the works. The tidal turbines of Nepthyd display a power of 1,4 MW each (their production could power 15 000 people in electricity), those of Normandie Hydro 2 MW.

The Robin des Bois association for the defense of marine environments is "absolutely against these projects" in the Natura 2000 zone, its president Jacky Bonnemains told AFP on Thursday. "The Raz Blanchand is an underwater torrent with major ecological functionality. Attacking it is like attacking Mont Blanc," he added.

Currently, only two tidal turbines are submerged off the French coast, near the island of Bréhat (Côtes d'Armor). They must be connected to the network "during the summer", indicated in June DCNS which designed them. They should then form the first park, in France and in the world, of tidal turbines connected via a single cable to the national electricity distribution network, according to DCNS, which has a similar project off the coast of Canada.

According to DCNS, the Bréhat project aims to show the technological feasibility of tidal turbines, while that of the Raz Blanchard aims to "demonstrate the tidal turbine economic model". The third step would be the opening of "commercial farms" of 50 to 150 units (or 300 MW) by 2023, according to DCNS. Until then, the manufacturer announces "costs divided by three".

This energy is subject to subsidies. For the Nepthyd project for example, France plans to pay 51,23 million euros, by means of a direct subsidy and advances which will be reimbursed "if the technology had to keep its promises", according to a source familiar with the matter. .

Abandonment of tidal turbines at Paimpol-Bréhat: the mayor asks Nicolas Hulot to intervene

Jean-Yves de Chaisemartin, UDI Mayor of Paimpol, denounced the decision of the EDF and Naval Energies groups to stop the testing of tidal turbines. A project that cost 70 million euros, subsidized by the Brittany Region.

(...)

This experimentation project for two tidal turbines started in 2011. In a press release, Naval Energies and EDF explained, on November 6, "[having] drawn experience feedback from the construction, immersion and testing of tidal turbines OpenHydro on the Paimpol-Bréhat experimental site. It brings this important phase of development to a close ".

The two tidal turbines, of 16 meters in diameter manufactured by OpenHydro, were immersed in 2016 current and were released from the water since April 2017, due to corrosion problems. The groups planned the commissioning of 2019 turbines.
The Normandy Hydro pilot farm project, which aims to install seven tidal turbines at sea in the Raz-Blanchard (Manche), is however being pursued by the groups. Likewise, "the experience feedback from Paimpol-Bréhat will benefit in particular the Bay of Fundy experimental farm in Canada, the Cape Sharp project led by Naval Energies", they added. These two technological demonstration projects, carried out on sites "with very different but complementary environmental conditions", aim to make it possible to use "important data" to optimize the design, reliability and performance of OpenHydro tidal turbines.

"Once the technology has been confirmed on the Canadian experimental project at Cape Sharp, EDF will be able to launch the industrial phase of the Normandie Hydro project," the groups said.

The tidal stream Sabella again immersed off Ouessant this summer

Brest 25 May 2018

The tidal turbine of the Breton SME Sabella will again be submerged off the island of Ushant (Finistère) from the end of August, after a series of tests and improvements on land from 2016, did we learned Friday from the company.

The "D10 will be re-immersed in the summer," said Jean-François Daviau, head of the SME, which employs 18 people, adding that the operation will take place from the end of August depending on the weather. .

The machine, a power of a megawatt, will remain immersed for three years, he said during an open day in the company's workshop in Brest, where is located imposing turbine 100 tons, of entirely French manufacture.

The tidal turbine will provide approximately 15% of the energy needs of the island and will have a storage system to partially offset the periods of production stoppages due to the stalls, the moments between two tides where the current is zero .

During its first immersion, between June 2015 and July 2016, the machine had provided only about 5% of Ouessant's energy needs.

Since returning to shore, the tidal turbine has undergone a series of tests and improvements.

"We doubled the electrical conversion chain so that if a component failed we could switch to the second conversion chain and continue to produce," said Jean-François Daviau in particular.

If a component were to be changed in the heart of the tidal turbine, laid by 55 meters, this would have a very important cost, he noted, stating that the operations of lifting and re-immersion of the machine graze the two million euros.

D10 is the only tidal turbine to have so far injected current of marine origin on the French power grid.

Sabella expects on the 2021 horizon, still off Ouessant, in the powerful current of the Fromveur, the immersion of two new machines, a megawatt also but 12 meters in diameter (D12), to cover between 35 and 40% of the electricity needs of the 800 inhabitants of Ouessant.

In addition to these projects, Sabella continues to promote its tidal turbines around the world by targeting non-interconnected areas of the national grid, such as in some islands in the Philippines or Indonesia, but also in Australia around some isolated Aboriginal communities or remote industrial and mining sites.

Another failure, not to say SCANDALE, French tidal ... Ah fob lobbies are still powerful in France!

https://www.rtl.fr/actu/debats-societe/ ... 7794260159

Ubiquitous situation for this tidal turbine manufacturing plant in Cherbourg closed a month and a half after its inauguration. This is total misunderstanding in the Channel while the EPR Flamanville announced a year of additional work and an extension of 400 million euros. It was for financial reasons that Naval Energie dropped the site of 5.500 square meters which was to allow each year the construction of 25 tidal turbines.

A state decision since the state owns more than 60% of Naval Group, the marine industry company. The project was launched in 2014 and some blame the executive for giving in to the nuclear lobby.

"This sector of the future, the State has killed it", is what local elected officials say. For Hervé Morin, the president of the Normandy region, the culprit has a name. "The one who has to point the finger is the one who roughly decides everything, this man is called Emmanuel Macron," he says. A paradoxical situation as the Minister of Ecological Transition, Nicolas Hulot, calls for a sacred union on the climate this Sunday morning in Le Journal Du Dimanche.
