EDITORIALWINDBLATT 01 20093Dear Readers,The cover story of this edition of Windblatt demonstrates the positive effects of ENERCON’sdecision to become involved in a country such as Portugal. With the last of the productionfacilities promised by ENERCON nearing completion in Viana do Castelo, Portugal is evolvingfrom an importer of wind energy converters into a manufacturer and exporter. Besides benefiting the environment, wind energy has brought jobs, economic growth, and business formany Portuguese companies. At the same time, ENERCON has created new capacities tosatisfy the worldwide demand for its wind turbines.The renewable energies directive is the most ambitious measure taken so far by theEuropean Union to curb climate change. By the year 2020, at least 20% of Europe’s grossfinal energy consumption must come from renewable sources. Each member state is given alegally binding target value (these targets are not really detailed; there is basically one number per country). En route, they must reach certain milestones, which are verified by theEU Commission. It is left up to the individual states how they achieve this goal. The countriesalone decide which instruments they deem suitable. This is a great success because triedand-tested promotion mechanisms for renewable energies such as the German RenewableEnergy Sources Act now remain untouched, contrary to the Commission’s original plans.The provisions concerning grid development are particularly important for the progress of therenewables sector. All EU member states “shall take the necessary steps” to ensure that anadequate transmission and distribution grid infrastructure is available for the continued development of renewable electricity, says the directive. Grid connection and the use of storagesystems for regenerative energy systems are to be supported. The directive explicitly suggestspriority grid access and dedicated connection capacities for regenerative energies as meansto accelerate the development of the renewable energies sector. Generation management –a growing nuisance today for wind farmers in Germany’s northern state of Schleswig-Holstein– can thus become a thing of the past and be limited to absolute emergencies. The directivestipulates that grid operators must be accountable to a regulatory body. This is good news inparticular for wind farmers in those EU countries with a high share of regenerative electricity.The ball is in the court of the grid operators! They must develop their grids and enable themto take in the decentralised energy production from renewable sources.Yours sincerelyAloys WobbenManaging Director ENERCON GmbH
WINDBLATT 01 2009NEWSFirst ENERCON workshop on gridintegration of power system operatorsE-82 next to high-voltage lines (Rhône Valley).Last November in Bremen, Germany,ENERCON hosted a workshop on the grid integration of wind energy for transmission systemoperators that was attended by 24 representatives from ten countries. “Manufacturers andsystem operators need to achieve a commonunderstanding of the demand, the possibilities,and the challenges of grid integration of windpower. This is the only way we can ensurecontinued success in this area,” said StephanWachtel, Head of Technical Support in theENERCON Sales Devision.ENERCON presented its latest developmentsin the area of wind energy converter (WEC)technology addressing grid connection andsystem integration. Afterwards, specific topicssuch as the fault-ride-through (FRT) capabilityof WEC were discussed. Even though this feature has been a requirement for the connection of wind farms to high-voltage grids for along time, the details still make for fruitfuldiscussions. ”There are more and more gridsthat experience a significant increase in thenumber of feed-in sources; therefore, the specifications for FRT requirements are frequently still fluid,” says Wachtel.Another topic for discussion was the way inwhich WECs can provide reactive power duringand after the occurrence of faults in the grid.While representatives from Canadian grid operators emphasised its importance for powersystem stability, Kevin Smethurst from theBritish system operator NGET highlighted theneed of smaller power systems for the fast return of active power after the clearing of gridfaults. Representatives from the manufacturerthen explained how ENERCON WECs with theirFACTS properties can react flexibly to thechanging conditions in power systems.“These were actually two separate wind farmswhich we took over in 2006 and merged,”reports Andrus Zavadskis, technical director at“4 Energia” based in Tallinn. The company isacting on behalf of the owners AS Freenergy,Tallinn, and the Norwegian AS Vardar Eurus.Funding was provided by two Baltic subsidiaries of SEB and Hansabank/Swedbank.Beside wind energy technology, the provisionof reliable and validated data for systems planning and project applications was discussed.Detailed information was given to explainENERCONs detailed approach to validate andcertify the performance of the WEC by accredited bodies. This elaborated process washighly appreciated by the attendees and understood as a major step on increase the quality of wind power integration and do reducerisks and failures.The wind farm is situated only ten kilometresoff the Baltic coast near the Latvian border.The area covering more than 38 ha is bisectedby a 110 kV cable line. Both farms are connected to this line at one point of common coupling. The electricity is being bought by theLithuanian utility, AB Lietuvos Energija, whowill be paying the set power purchase price of8.7 ct./kWh over a 20 year period. Forecastsestimate that the E-82s will run at full load approx. 2500 hours per year. Compared to othersites worldwide this is a fair average. “We expect an annual yield of 35 million kWh,” saysZavadskis. “The farm will help Lithuania increase its share of green power.” Currentlyonly 3.5 % of the country’s electricity demandis covered by renewable energy sources. Thegovernment plans to up the share to 10 % bythe year 2010. According to “4 Energia”approx. 200 MW of wind energy is needed toachieve this goal.ENERCON underlined its leading position ingrid integration technology: “ENERCON WECscombine optimal performances on the gridwith the capability to support the acceleratedtransformations required in transmission anddistribution systems for the integration of renewable energies,“ Wachtel concluded.Lithuania: Sudenai/Lendimai windfarm taken over by customerPicture: 4 Energia4Andrus Zavadskis, Technical Director of “4 Energia”.In December, ENERCON handed over theSudenai wind farm in western Lithuania to theoperators, “4 Energia”. The project is made upof seven E-82/2 MW turbines perched on 77metre steel towers in an area between thetownships of Sudenai and Lendimai, in Kretinga County. Four turbines are situated in Sudenai, the other three in Lendimai.Recently, “4 Energia” also launched operationsat the E-70 wind farm “Virtsu 2” in west Estonia. More that 100 guests were at the inauguration ceremony, including the Estonian Minister of the Environment, Jaanus Tamkivi,representatives of various parties and localcouncils. “Virtsu 2” is located on a headlandwhich only emerged from the Baltic Sea about1500 years ago. Ferries to the largest Estonianisland, Saaremaa, depart from Virtsu.Latvian power company, Latvenergo, ispicking up the tab for this green electricity.“Since the Latvian power system is in deficit –most of the year their consumption is higherthan their production – at the moment purchase prices in the country next door are betterthan in Estonia,” explains Zavadskis.Martin Kruus, former manager for renewableenergy projects at the state owned utility,
On shore, “4 Energia” is currently planning toinstall more than 250 MW wind energythroughout the Baltic States. At the moment,further projects in cooperation with ENERCONare under way in Tooma, Estonia (6 E-82s) andMockiai, Lithuania, where this year 12 MW(E-82) will be installed on 108 m concretetowers for the first time in the Baltic region.EWG study: 100 % power supply fromrenewables feasible by the year 2040The worldwide installed wind energy capacitywill double from 120 GW (at the end of 2008)to 240 GW over the next three years. This is theresult of a study carried out by the independent Energy Watch Group (EWG) based in Berlin. The study explored four different scenariosof power consumption increase with a view totheir impact on wind energy generation.ENERGYat Hanover Fair(Hanover/Germany)20.04. – 24.04.2009Technology tradeshow for theenergy mix of the future(ENERCON in hall 27)www.hannovermesse.de/energyHe emphasises that, contrary to IEA assumptions, the expansion of wind power generationdoes not solely depend on the price of fossil fuels and the alleged cost advantages of nuclearpower. There are other important factors: Thefree availability of the resource wind; the ability to avoid the risks of fuel price developments;new regulations for grid operation; as well as aworldwide market growth thanks to ever betterand more affordable wind power 5New Zealand Wind EnergyConference 2009(Wellington, New Zealand)20.04. – 22.04.2009Exhibition and conference onNew Zealand’s wind industry andwider energy sectorwww.windenergy.org.nzEWG sets a counterpoint to scenarios published by the International Energy Agency (IEA)which assume a much lower basic growth aswell as a sharp decline of new installations inthe middle of the second decade. “The IEA forecasts are too pessimistic.
