GEV MP C200-275 kW32-m rotor55/60-m heightEnergythroughout the worldIn remote locations, it is very difficult to install windturbines. However, such sites often have the strongestneed for a dependable, cost-effective and self-reliantsource of energy – like wind energy.We at Vergnet took up this challenge. For more than 20years we have been developing innovative, practicalsolutions to the specific concerns of all complex sites,either difficult to reach or subject to harsh conditions,such as hurricane-prone areas or salty environments.Like all our Farwind turbines, the GEV MP C is both robustand light. Thanks to its guy-wired tilting mast, it is veryeasy to transport and install anywhere in the world, andcan sustain hurricane winds when secured to the ground.The GEV MP C meets all the specific requirements ofsmall grids and outperforms any turbine of its class.All these assets have transformed a technologicalbreakthrough into a commercial success, with more than500 GEV MP-type wind turbines running worldwide.Easy to transportSuited for the harshest conditionsEasy to installRobust and long-lastingGround-level maintenanceHurricane-proofkW/hHigh performanceRemote supervision
A light, compact and versatile designLightweight structureDespite being 55m tall, the GEV MP only weights 20 tons.It is twice as light as a conventional wind turbine for the samerated power.Compact nacelleTwo nacelles can fit in a standard 20’ container.2-blade rotor - Exclusive lowering systemThanks to its 2-blade design, the GEV MP can be lowered tothe ground for maintenance operations and blade cleaning.Using an integrated winch, the whole machine can be loweredby two people in an easy and safe operation that takes lessthan one hour.Light guy-wired towerComprised of 5 x 11.88 meters modulars, it also fits into40’ containers.Self-erecting concept4The whole turbine is assembled on the ground, and thenerected using an integrated hydraulic winch. No crane isrequired. Only a forklift is necessary for the assembly.Reduced foundationThe light, guyed tower allows for a much smallerfoundation; therefore, the amount of concreterequired is reduced to only 15m3. That’s 80%less than conventional wind turbines of thesame class.Hurricane-proofIn case of a weather alert, any wind farm can be rapidly secured,since the lowering operation takes less than 1 hour. Oncefastened to the ground, a GEV MP can sustain up to 300km/hwind gusts (a Category 4 hurricane).3Earthquake-proofThe guyed tower’s adaptable architecture alsoproves efficient in areas prone to seismic activity.Easy to tranportGround-level maintenanceDesigned to fit in five 40’ standard containers (bladesAll maintenance operations can be performed at groundexcluded), the GEV MP can be shipped easily andlevel thanks to the lowering system, which drasticallycost-effectively. Standard trucks, unpaved roads, islands,reduces maintenance costs, as well as downtime.hilly countries.

An all-terrain wind turbineHighly resistant bladesOur rotor blades feature an optimized design. They are manufactured in our own facilities usingstate-of-the-art methods: a vacuum infusion process, appropriate finish processes including gelcoat, filler and edge protection, and disposable anti-abrasion strips.Anti-corrosion treatmentThe mast and all exposed parts are protected by a special coating, which ensures effectiveprotection during the entire usage time even in wet, salty, corrosive or abrasive conditions.Robust designAll parts of GEV MP are made from superior quality materials. Most parts are standard andwidely used in many industries, which guarantees their reliability. Major cast components including rotor hubs are made of spheroidal cast iron. The GEV MP isdesigned to bear 365 grid outages per year, compared with 20 per year forconventional turbines.All-terrain generator4The GEV MP features a robust and reliable squirrel-cage generator, suppliedby a first-class specialist. It is designed to operate even in extreme weatherconditions: from -20 C to 50 C 100% relative humidity marine environments (less than 100m from the seashore) IP 55 sealing protection specific tropical corrosion treatment of the stator and rotor,including stainless steel greasers, screws and fan coverProtected sensors varnish coat on electronic componentsto withstand possible condensation High protection grade sealed connectors (up to IP 67) EMC immunitySuited forthe harshest conditionsTeetering hubThrough its rubber/metal bushing,this innovative technology reduces stress on the whole structure,including the drive train and mast, by 35%. It thereby reducesmaintenance costs and provides a longer turbine life.Robustnessand reliabilityOur 20 years of worldwide experience helped us designA wind turbine must withstand unequalled loads andGEV MP as a real world traveler.stresses, and endure even more hardships in hurricane-Perfectly protected from aggressive elements, includingprone areas.

Controlled powerHigher energy production even in hurricane-prone areasThanks to its unique lowering system, GEV MP can be installed in places where only reinforcedclass-1 conventional wind turbines previously could be installed. With a 32-meter rotor and a height of55-meters, the 804m2 rotor swept area maximizes wind potential.Shock absorberA mechanical shock absorber evenly adjusts the torquevariations. This device reduces the stress on the drive train andhelps produce a pure sine-wave signal.Hydraulic pitch regulationThe pitch regulation allows accurate setting of the power output,cancels any risk of rotor overspeed and ensures fast and failproofstop of turbine.Safety systemsAll the safety systems comply with international standards: aerodynamic braking system through pitch regulation,including individual backup power units in case of supplyfailure safety rotor lock system to ensure safe service operations lightning protectionINDUSTRIAL PLCThe PLC (Programmable Logical Controller) is sheltered in theelectrical building. It constantly monitors all the necessaryparameters: Wind data (direction and speed) Wind turbine parameters (rotor speed, blade angle,yaw position, generator power output.)V-SCADATM real-time production monitoring, either remote or on-site allows recovery from system failures directly from aremote computer or from Vergnet headquarters:no need to send a technician. records data and establishes statistics in graphical,user-friendly forms adapted to digital or analog telecommunications system(public phone wire) backup protection in case of a grid outage by a batterylocated in the electrical buildingkW/hHigh performanceRemote supervisionThe whole GEV MP is designed to make the most of windAs it is designed to be installed anywhere in the world, apotential.

Some GEV MP wind farmsEritreaTrip to the end of the Earth at AssabSand storms, scorching heat, corrosive air, undeveloped logistics, unstablegrids. In Eritrea, extreme conditions make it far from easy to install a windfarm. However, this country had a strong need for a cheap, self-reliant sourceof energy. Vergnet Eolien took up this challenge and installed a wind farm inAssab in 2007. Being easy to transport, to install and to operate, the GEV MPhas turned out to be particularly reliable and high performing.6GuadeloupeGEV MP gets a jump on Hurricane DeanIn the Caribbean, Vergnet wind turbines rapidly turned out to bethe market benchmark, as the only effective answer to hurricanehazards.On August 16, 2007, while Hurricane Dean was approaching, localcrews lowered the 216 wind turbines located in the Caribbean inrecord time: 14 hours. Among them, the 27 turbines of Guadeloupe,which were securely fastened to the ground, sustained more than 250km/h wind gusts. Once Dean passed over the island, the wind farmsquickly resumed production, maintaining availability rates above95%.AustraliaSuccessfully combining wind and diesel energyThe Coral Bay wind farm perfectly demonstrates Vergnet’s knowhow regarding wind/diesel coupling and high penetration rate.Installed in a very isolated, cyclone-prone site, the farm includesthree GEV MPs, which are coupled with seven low load dieselgenerators, with energy storage through flywheel. The completewind farm supplies 95% of the local grid production, and offersup to a 90% penetration rate.
