This day was fantastic for the wind! :D

More 7 GW 10h30 to now.

GW peak at 7.456 13h45!

the previous record was beaten in France which was the 6.994 21 October 2014 GW.
see here : http://lenergeek.com/2014/11/21/octobre ... rancaises/

And specifically the opening day of the COP21.


As there are now 10 GW of wind power in France, it means instant load factor 75%.

The record to have its price tag!

The first victim Breton wind storm

February 8 2016 Telegram

impressive result of the storm: wind turbines located in the locality Pennalé in Dinéault (29), was partly destroyed. Two of its three blades have indeed been affected. The other three turbines are they intact and continue to run. For now, we do not know when it happened: he is a local resident who alerted the police, who visited the site. The area was secure because of debris on the ground.
This is the first wind turbine was erected in Brittany, 1999.

Norway will build the largest wind farm on land in Europe

AFP 23 Feb. 2016

The Norwegian electricity producer Statkraft and its partners announced Tuesday an agreement to build Norway's largest wind farm in Europe, an investment of 1,1 billion. Consisting makes six wind farms to be built near Trondheim (center), the project with a capacity of 1 000 megawatts should see the first sod given in the spring for an operating setting 2020.


He will represent one more to him than the current wind power capacity in the country according to the news agency NTB, and provide enough energy to power the equivalent of 170 000 household electricity and heating, said in a statement Statkraft's largest producer European renewable energy through hydropower.

"With this 1 MW project, we are becoming one of the main players in onshore wind power", underlined the group's managing director, Christian Rynning-Tønnesen. The 278 3,6 MW turbines each were ordered to the Danish Vestas. The project was given birth in pain. Statkraft had a given time, considering its lack of profitability, but resumed studies in November to find a more economical solution under pressure from the Norwegian State, its shareholder to 100%.

The energy company has instead had to give juicy offshore wind projects in the UK after a volte-face of the government, to fill a budget hole, reversed his decision to give up 5 billion crowns (528 million euros) dividends on 2016-2018 period.

"This is one of the largest industrial projects on land in Norway and it creates jobs," said head of government Erna Solberg, quoted by national media. "This will give a boost to renewable energies in Norway." In addition to Statkraft, which will control 52,1%, the project brings together the local energy company TrønderEnergi (7,9%) and the Swiss consortium Nordic Wind Power (40%) comprising Credit Suisse Energy Infrastructure Partners and the Swiss energy group BKW.

The US world champions of wind power generation with 190 2015 TeraW.h in, just before the Chinese.

The state of Iowa USA champion with 31% of electricity production from wind.


US number one in the world in wind energy generation

March 1, 2016 evwind

The United States continued to lead the world in wind energy generation selon Recently released data by the Global Wind Energy Council (GWEC) and by the US Energy Information Administration (EIA).

Over 31 percent of Iowa's in-state electricity generation from wind cam last year - marking Reviews another major milestone. This is the first time a wind HAS Supplied state with more than 30 percent of annual electricity icts. Iowa, Kansas and South Dakota all generated more than 20 percent of Their electricity from wind in 2015.

.............


Wind Produced over 190 million megawatt-hours (MWh) in the US last year, enough electricity for about 17.5 million typical US homes. China is close behind the US at 185.1 million MWh and Followed by third-up Germany at 84.6 MWh. ALTHOUGH China HAS Nearly twice the installed wind power capacity as the US, strong wind resources and generation-based policy-have US Helped build Reviews some of the MOST productive wind farms in the world.
.....................

The US now HAS Nearly 75 gigawatts (GW) of installed wind power capacity. Last year, wind 8.6 installed GW of new electric Generating capacity, making it the Largest source of new capacity ahead of solar (7.3 GW) and natural gas (6 GW). An additional 9.4 GW of wind power Was under construction at the start of 2016, 4.9 Reviews another with GW in advanced stages of development.

Lily, a novelty in wind turbines

GN, the 14 / 01 / 2016 batiactu.com

VIDEO. Take the sea wind optimally and turn it into energy is a challenge trying to raise the water lily floating wind. Real engineering jewel presented to Francois Hollande, she received an innovation award in the competition for the French Tech COP21. Zoom.

floating wind technology is booming. Alongside Winflo and Ideol Oceagen, two French industrial initiatives, another company is hatching: Water Lily. Created in 2006, the start-up has developed a vertical axis machine, a first prototype of a power 35 kW has been installed on land, 2011, in Ferques (Pas-de-Calais). The first wind turbine 6 meters high to validate the concept.

Three years later, thanks to the financial support of several investors including Areva, BPI or IDInvest Partners, the company manages to set up a second prototype, of 600 kW, in Fos-sur-Mer (Bouches-du-Rhône). This time, the dimensions are quite different: 40 meters high for 50 meters in diameter. It is quite simply the largest vertical axis wind turbine in the world. Installed on land, it is instrumented to generate significant experience feedback. In June 2015, the profile of the blades, initially inclined and in a spin, was replaced by straight and vertical blades. The company explains: "These blades are lighter and easier to manufacture, which significantly reduces the cost of the wind turbine and therefore the price of energy."


A marvel of technology


But the developments do not stop there: in March 2016, a new architecture will be tested on the machine. The three right blades will be no more than two. "This architecture has proved to be more advantageous for an offshore application since it allows, among other things, to put the blades in flag position, a position which limits the force exerted by the wind on the wind turbine and thus protects the machine in case of extreme wind, without having to oversize the float, ”announces Nénuphar. The evolution will also make it possible to vary the "pitch", the variable pitch of the blades. Enough to optimize energy production and further reduce wind resistance during storms.

Because the ultimate goal is to deploy this type of machine at sea, on floats anchored offshore where the funds are too important to install offshore wind turbines with horizontal axis. The company estimates that the technology based on the vertical axis outperforms conventional machines. Not only to the wind in all directions is simple, unlike a horizontal turbine must be oriented to face him, but more wind Lily is less susceptible to lodging, so less likely to tip over.


A promising future


Pushing the concept even further, the engineers of the French start-up - which now employs nearly 50 people - imagine a concept where two contra-rotating wind turbines (which turn in the opposite direction) are coupled on a single float. Named "Twinfloat", it will develop more than 5 MW of power. Doubling the swept air surface and creating a forced flow between the two axes would greatly increase the conversion efficiency (or power coefficient). The latter, which amounts to 43-35% for conventional machines, exceeds 50% on vertical axis wind turbines and could reach 65% on "Twinfloat". In addition, these floating machines make it possible to densify the farms, by installing more turbines on the same area, because their wake in the atmosphere is less disturbing than that of conventional wind turbines.

Image

The next step is to deploy a machine at sea, in order to commercially offer the Twinfloat on the horizon of 2021. Remember that France has already identified four areas for the development of floating wind power, three in the Mediterranean and one in Britain. A call for proposals was launched in August 2015; it will be ended 4 April. According to professionals in the sector, France could have 6 floating wind GW at the end of the next decade. A long way to go.

EDF Energies Nouvelles inaugurates the largest wind farm in France near Perpignan

Usine Nouvelle the 24 / 06 / 2016

The Minister of the Environment, Energy and the Sea Ségolène Royal and the president of the EDF group Jean-Bernard Lévy inaugurate this Friday, June 24 "the Catalan Wind Farm", a 96 MW park, made up of 35 machines positioned in four municipalities in the Pyrénées-Orientales. They will also visit the EDF Energies Nouvelles European supervision center, located in Colombiers, near Béziers.

"the Catalan Wind Farm", a 96 MW park, made up of 35 machines positioned in four municipalities in the Pyrénées-Orientales.

It is finally time for the inauguration, this Friday, June 24, for "the Catalan Wind Farm", deployed by SAS Catalan Renewable Energy Park for EDF Energies Nouvelles in four municipalities in the Pyrénées-Orientales: Baixas, Calce, Pézilla-la-Rivière and Villeneuve-la-Rivière. Composed of 35 Vestas machines with a total power of 96 MW, it is the largest wind farm in service in France. This infrastructure required an investment of 140 million euros.

What explain the presence at the inauguration of the Minister of Environment, Energy and Marine Ségolène Royal, alongside the President of EDF Jean-Bernard Lévy group and CEO of EDF Energies Nouvelles Antoine Cahuzac (also Executive Director in charge of the group Pole Renewable Energy).

140 million euro investment

The wind farm 96 MW, which cost 140 million, is expected to produce 240 GWh.

http://www.usinenouvelle.com/article/ed ... an.N399007

EDF has commissioned Friday near Perpignan (Pyrénées-Orientales) its largest wind farm in France, a project that took nearly ten years to complete and had to use a unique technology to accept his 35 wind.

...............
Aeolian stealth

EDF therefore used a military-inspired technology imagined by the British company Qinetiq and developed in partnership with Vestas to develop so-called "stealth" or discreet wind turbines. Thanks to a kind of ink integrated into the materials of the blades and part of the mast, the radar waves are no longer diverted or blocked by the wind turbines. "This is a world first on an industrial scale" indicated Thierry Le Gall, head of research at Qinetiq, who specifies that the company has been approved by the French Ministry of Energy to model the impact on weather radars -France for all wind power projects on French territory.

The ambition of EDF

"Without this first technology, this project would not have been possible," explained Mr. Lévy. This park is also for the electrician a new illustration of his ambition in renewable energies in France and in the world.
