3 The stake of the renewable energies The energetic needs of the planet could increase by 60% within 2030 as reported by the International Agency of Energy. Excepting draconian measures of reducing the intake, where will we find them? The global warming is as measurable as alarming, reducing the green house effect gases is urgent. The wind driven in the lead According to ADEME, the exploitable renewable energies field, around 2010, will be by order of availability: the wind power, the biomass (wood, farming residues), the small hydroelectricity, geothermal science and solar energy. Born from the transformation of the wind power into mechanical energy, converted itself into electricity, the wind energy doesn t generate green house effect gases nor waste. The wind power looks particularly adapted to the French intake; the windmills produce more during the winter, time when the demand of electricity is stronger than in summer. View over the wind driven throughout the world Among all the renewable energies, the wind power counts the strongest expansion. From 4800MW in 1995, the world wide production was multiplied by 12 in 10 years to reach 59000MW in More than 50 countries in the world develop their installed capacity with Germany in the lead (19000MW), Spain (11000MW), the United States (9149MW), India (4430MW) and the Denmark (3122MW). In this country, the wind power ensures already 20% of the electricity production, and Spain aims the 15% in Proof that the wind power could supply on short-term a significant contribution to the electricity production without carbon. 3

4 France, finally in the race! The French wind power bed is the second in Europe, after England. It is estimated of 50000MW, from which 30000MW in offshore. After a particularly slow and difficult start, the French wind park seems to take off. It reached close to 1500MW at the end of 2006; this is little compared to the German and Spanish neighbors, and away from the 10000MW planned in the law of the 13th of July 2005 program. It fixes the orientations of the politics of energetic, particularly: producing 21% of the electricity intake starting from renewable sources in To open the way for the wind power field, it is important that the tools present in the law be operational (creation of wind power development zones, increase of the buying price of the wind driven electricity and lasting several years programming of the investments). The investigation made in May 2006 by the renewable energies syndicate counted a grouping of projects on all phases of 20000MW. The 10000MW project seems then doable, on condition of lifting up some of the obstacles, in particular the one of the cohabitation of the wind parks with the meteorological, aeronautical or military radars, which leaves dangling close to 3000MW of wind power Scenario: a 10000MW wind park produces 25 million of MWh and supplies more than 10 million dwellers. 4

5 Snet Thrusts 4 parks on the front page, or 40 MW Picardie, Bretagne and Champagne- Ardennes are the regions chosen by Snet to exploit the winds. 3 Aeolian parks will come out from the grounds in 2008, and other parks are already being planned. Lehaucourt : 10MW Situation: Aisne, 9 Km away from Saint- Quentin and 30 Km from Cambrai Park: 4 windmills, 125 m high, inaugurated in March 2007 Developer: Espace Eolien Developpement Constructor: Nordex Ambon : 10MW Situation: Morbihan, 90 Km away from Nantes Park: 6 windmills, 121 m high, permit given in 2006 Developer: Valorem Constructor: Ecotecnica, reception of the park planned for End of March 2008 Les Vents de Cernon : 10MW Situation: Champagne- Ardennes Park: 4 windmills, 125 m high, permit given in 2006 Developer: Nass& Wind Technology Constructor: Nordex, delivery of the machines planned in April 2008 Muzillac : 10MW Situation: Kilometers away from Ambon Park: 6 windmills, 111 m high, permit given in 2006 Developer: Valorem Constructor: selection process in progress 5

6 Close-Up on Lehaucourt A local initiative The Lehaucourt town is situated in Picardie, North East of Aisne, 9 Km away from Saint- Quentin and 30 Km away from Cambrai. It is the Mayor of Lehaucourt who proposed the site in In the middle of big extensions of cereal culture, stand the hills of 130 to 160 m high, dominating by 60 m the valley of the Somme and of Omigon, and by m the valley of Escaut. After the presentation of the project to the two concerned land owners, the studies were launched by the Espace Eolien Développement. 6

7 Chronology of the project May 2003 The study over the environmental impact doesn t reveal particular constraints. October 2003 Launch of the landscape study and installation of a 60 m mast to measure the wind during 14 months. November 2003 After the presentation of the project to the president of the community of the towns of Vermandois, a public reunion was held in Lehaucourt. After the general agreement, the building permit demand is deposited. November 2004 The Aeolian balance sheet is positive. Dominating South- West winds, an average speed of 7, 02 m/s to 80 m, what to make a dwellers annual intake (except heating). February 2005 Obtaining the building permit. March 2006 The turnkey contract signed with Nordex gets in effect. 31st of July 2006 Startup of the construction yard. Earthwork of the beddings at 2, 75 m depth, iron frameworks and pouring the concrete, pose of the cables: the construction yard is finished in 5 months. January 2007 Delivery and mounting of the Windmills. February 2007 Start of the essays. March 2007 Reception of the park according to the Nordex contract and commissioning. 7

8 The mounting movie The delivery of the windmills : Towers, blades and nacelles come by exceptional convoys (10 by windmill); as the crane assembled on the site (700 tons and 6 convoys). The tower mounting : The first section is sealed to the beddings by a bridle including 120 bolts locked with a dynamometric key. Positioning of the 3 next sections. Total: 220 tons and 80 m of height. The mounting of the nacelle : it is equipped with an anemometer to measure to speed of the wind, a wind vane to measure its direction and allow the machine to orient itself with an optimal way, a transmission shaft ensuring the connection between the blades and the multiplier. Total weight: 50 tons. The construction of the rotor : the 3 blades of the windmill (11 tons and 44 m long, each) are mounted on the hub (23 tons) and the whole is mounted over the nacelle. Timing : three days of mounting per windmill. Started on the 22 nd of January 2007, the assembling of the 4 windmills ended on the 2 nd of February View over the park: 4 windmills N90 (2, 5 MW) 125 m high (80 m of mast + 45 m of the rotor s radius) and spaced by 450 m. an investment of about 10 million euros. 8

10 Unbeatable on the wind power How does it work? Like a windmill, but 2500 times for a 2, 5 MW Aeolian. The wind pulls the blades, called rotor, which pulls afterwards an electric generator located in the nacelle. An Aeolian starts producing with a wind of 10 to 15 Km/h, and attains its full capacity with a wind of 45 to 50 km/h. the Aeolian is connected to the electricity distribution network. At Lehaucourt, a line of 8, 1 km was created by EDF to connect the Aeolian s delivery post to the source post of Saint- Quentin. What noise? The Aeolian branch made considerable technological progresses these past years: ultra silent gears, transmission shafts on bearings or padded nacelles. At 400 m the voice level of a wind park is close to the one of a low voice conversation. Let s point that the legislation in the matters of noises in France is the strictest of Europe. Who makes the Aeolians? The pioneer countries of Aeolian are also the leaders of this industry in Europe: the Danish Vestas and Nordex (around 2900 Aeolians in more than 31 countries), the Spanish Gamesa Eolica and Ecotecnica, the German Enercon, next to the giants of electricity General Electric and Siemens. What risks? The Aeolians of Lehaucourt are fixed on impressive foundations: 2, 75 m deep, 36 tons of high steel and 800 tons of concrete per machine. Each Aeolian is driven by a computer which permanently controls all the mechanical and electronic parameters, and causes the immediate put into security in case of anomaly. When the winds attain 90 km/h, it automatically stops the Aeolian and the blades retract to allow a minimum hold of the wind. When stopped, the Aeolians are conceived to resist more than 215 km/h blasts. 10

12 A walk in Lehaucourt A flowery village The town of Haucourt took the name of Lehaucourt in It goes over 898 ha dominated by the cereal and beetroot fields, and counts 837 dwellers. To see: the church Saint- Gery and its large cellars (called muches ), the neighborly houses and the Farm of Thorigny for their architecture and the shores of the Saint Quentin canal for a fishing. A dynamic agglomeration community The community of the towns of Vermandois, created in 1994, puts together 53 towns (including Lehaucourt) and dwellers. It develops a territory project that conjugates tourism, economical development and environment and has approved the project of the Lehaucourt wind park that conciliates the ensemble. You will come across known companies like Le Creuset and its culinary pots, Alcatel Cable France or the tights of Le Bourget. On the touristy side, embark on the last toueur * of France for an unseen tow along the underground canal of Riqueval (5, 6 Km). Discover the color of the weaving and of the secret embroidery of the region, at the house of textile. Get into the Vermandois Express and take off from the valley of the Somme to the valley of Oise, in 3 rd class or in the Art Deco restaurant wagon. And to breathe, walk on the vestiges of the Oppidum, a military camp built by the Gaul or go on a hike over the 80 km of paths of the Vermandois. * : Electric boat that moves over a chain fixed in the bottom of the canal.
