E D I T O R I A L WIND BLATT01 | 2008 3洞察一切
Dear Readers,
In 2007,the Nobel Peace Prize shared in equal parts between the Intergovernmental Panel on Climate Change (IPCC) and Al Gore finally brought the question of climate change into the lime-light.The renowned prize awarded for efforts to prerve nature and world peace is a means of rousing public awareness that curbing man-made climate change is vital for the survival of mankind.
Renewable energies are already making a considerable contribution to cutting carbon dioxide emissions.In Germany in 2006,wind energy alone saved more than 26 million tons of CO

ces Act (EEG).But there is still immen potential for wind energy development at inland sites.If our country wants to provide more clean power and achieve changes in its energy supply system,it is esntial that we make u of this potential.ENERCON’s most outstanding technological innovation to date is the construction of the E-126 prototypes in Emden and Cuxhaven in 2007.The new multimegawatt turbine clearly demonstrates how efficiently the wind’s power can be ud.With an output of more than 18 million kWh p.a.(at expod sites performance it can even surpass 20 million kWh) this model can provide over 5000 hou-holds with green electricity – meaning that wind energy is now by far the most economical renewable energy production source.
This fact should further encourage the promotion of renewable energies.The German Rene-wable Energy Sources Act,currently being reviewed in parliament,should not for example impede further developments of the most successful means of preventing CO

far.This includes discontinuing,sooner rather than later,gradual yearly reductions of the power purcha price for wind energy.Should politics fail to take rising prices for raw mate-rials and the subquent increa in the price of wind turbines into account,the conversion to environment-friendly electricity supply could come to a grinding halt.
In order for Europe to attain its goal of providing 20% of their power supply from renewable sources by 2020,fixed feed-in tariffs are indispensable.So far,the have been the only means of guaranteeing cost-effective,regional developments in all renewable ctors.This efficient instrument of promoting renewables should not be jeopardid by trade models which only render developments more expensive and hamper advancements as experienced in various European countries.Europe is greatly in need of rapid expansion of the most efficient strategy of avoiding CO

The MTA Metalltechnologie Aurich plant with three parallel production bays is loca-ted in the Aurich industrial estate between Tannenhaun and Sandhorst.MTAs imme-diate neighbours are Mechanic Anlagenbau G mbH and Induction G eneratorenfertigung G mbH,the two main customers of the components manufactured by the new exclusive ENERCON supplier.
The range of products includes almost all components of the E-82 nacelle casing –stator casings,spinner ctions,blade extensions,etc.; as well as fully finished ready-to-install cast components – main carriers,axle pins,and blade adapters; and precily shaped steel rings for stator production.Technical Manager Ralf Mühlenbrock points out the new large

welding robot at MTA.“For the first nacelle casing ction,the robot maker’s support technicians assisted us with the program-ming.For the other parts,we are doing all the programming ourlves.”The operator moves the robot’s articulated arm towards an aluminium sheet:Using lar optics,the robot detects the ams and geometry of a blade extension so that it can automatically find the weld ams later.Says Mühlen-brock:“We are planning to weld around 500nacelle casings per year.”
Staff from an Italian manufacturer are t-ting up a large vertical boring mill for the turning and milling of stator support rings.In the same factory bay,the support rings are asmbled from steel plate.They carry the copper windings of the stator that

MTA Metalltechnologie Aurich GmbH – a new company of the ENERCON group – started manufacturing nacelle casings and machining cast components and steel parts at the end of 2007. Preparations for the manufacturing of generator rings are currently in full swing. Customers will be Mechanic Anlagenbau GmbH and Induction Generatorenfertigung GmbH,both bad in Aurich. “We will create about 80 new jobs here this year”,says technical manager Ralf Mühlenbrock.

A lot of welding tasks will continue to be done by hand.
