Wind projects – international

What are the goals of the EWS Consulting internationally?

The EWS Consulting has developed its know-how in Austria but, in the mean time, now has projects in Europe and soon even across the ocean. The EWS Consulting adheres to its high standards of quality at home as well as outside its borders. These high standards of quality give our customers confidence in our work.

Wind Farm Baia - Romania

Our work in this part of Europe started with projects on the northern Black Sea Coast of Bulgaria. The project Baia 1 led us to the northwestern corner of Romania.

Customer: Holrom Renewable Energy s.r.l.
Installed capacity: totaly 17 MW
Start of operation: Baia I 11/2009, Baia II 07/2011
Special characteristics
  • Repowering with know-how from the EWS consulting
    The first step was taken when a Romanian wind farm operator installed 3 small second-hand wind turbines on a hill near Baia. The next step, a larger wind energy project at the site, was carried out with the Austrian company Imwind Elements GmbH as partner. The new wind turbines of the Wind Farms Baia 1 are two Vestas V90, one with 2 MW and one with 3 MW. Two of the old wind turbines were disassembled.
  • Implementing projects with Romanian partners and specialists
    The EWS Consulting was responsible for the wind farm layout, energy yield calculations, turbulence calculations and for construction management. Employees of Holrom supervised construction at the site and made sure that official regulations were carried out. Due to the good cooperation between the two companies, the project could be implemented in the difficult terrain.
  • Expansion: Project Baia 2 started in August 2010
    In August 2010, construction began on Wind Farm Baia 2 with an additional 5 wind turbines. The EWS Consulting was again responsible for construction management.

Wind Farm Nejkovo - Bulgaria

Bulgaria is one of the biggest growth markets for wind power producers because of its excellent wind resources near to the coast. Due to its supportive energy policies featuring a feed-in tariff, 2010 saw especially remarkable growth. Wind developer Windkraft Simonsfeld was also active in the region. In September 2009, two of their turbines began operation in Nejkovo, Kavarna region. The two turbines were sited and built in record time under the construction management of EWS Consulting.

Customer: Windkraft Simonsfeld Holding GmbH
Installed capacity: 2 x 2 MW
Start of operation: 09/2009
Special characteristics
  • First project for Windkraft Simonsfeld in Bulgaria - also the hundredth megawatt for WKS
  • WKS has laid the groundwork for the taking over of numerous wind farms by Austrian operators in Bulgaria 
  • Planning for additional wind turbines in the region is moving full speed ahead.

Resource assessment for projects in Bulgaria, Romania, Slovakia, Czech Republic, USA

Even in regions without easy tie-in to the grid or attractive feed-in tariffs, there are many project developers who want projects finished at the right time. We at EWS Consulting are there from the site search to the micrositing of turbine locations. Our calculations are the basis for decision-making by financing institutions. Our Austrian standards and quality criteria give you security.

Oberzeiring

Tauernwind Farm Oberzeiring

The Tauernwind Farm Oberzeiring was the highest wind farm in Europe at the time of installation (1,850 meters). The extreme weather conditions (ice, snow, strong winds) and the sensible alpine flora and fauna presented a great challenge to the planners. New transport methods were created which made it possible to overcome the long distances.

Customer: Tauernwind Windkraftanlagen GmbH
Installed capacity: 11 wind turbines, 19,75 MW
Start of operation: End of 2002
Special characteristics
  • EU project for researching wind energy in alpine regions
  • Installation in just six and a half months
  • Great precaution was taken to protect nature - e.g. the upper layer of grass was carefully dug out and, after installation, was set back in place.
  • Access road: 11.8 km long, 900 meters difference in altitude
  • Electrical connection: Electrical lines are 20.86 km long and crossed many streams and streets
  • Development of a special transportation concept
  • Transport of the rotor blades by helicopter

Sternwald

Wind Farm Sternwald

Right from the beginning, it has been a basic principal of the EWS Consulting to make sure that there is suitable distance from wind turbines to nearby dwellings. This means that, in a landscape scattered with houses, the only possible wind turbine sites are on exposed summits or in forests free of dwellings. Wind farm Sternwald was the first wind farm to be built in a forest.

Customer: Sternwind Errichtungs- und Betriebs GmbH & Co KEG
Installed capacity: 7 wind turbines, 14 MW
Special characteristics
  • Transport concept to keep disturbance to the forest at a minimum
  • Development of a special installation concept for better protection of the forest
  • Individual installation of rotor blades to prevent additional forest clearance
  • The rotor blades were assembled individually in 105 meters height above the tops of the trees.

Wind Farm Steinberg-Prinzendorf II

Austrian wind experts estimate that the wind energy potential in Austria amounts to three times as much as the total installed capacity of all wind turbines in 2008 (approximately 1000 MW). The utilization of this potential could be possible with just doubling the number of wind turbines. The magic word is "repowering". - In Steinberg-Prinzendorf this method was used for the first time in Austria to replace an earlier generation of wind turbines with 2 MW state-of-the-art turbines.

Customer: Windkraft Simonsfeld GmbH & Co KG
Installed capacity: 12 MW
Special characteristics
  • „Green Meadow" - Wind turbines were completely taken down for the first time in Austria in the course of enlargement of a wind farm.
  • The foundations were completely removed and disposed.
  • An environmental impact assessment was required for the enlargement of wind farm Steinberg-Prinzendorf I.
