The right choice of wind turbines and layout is the main task in the planning of wind farms.
Over 50 competing manufacturers world-wide are presenting almost the same amount of concepts to gain the affirmation of the project managers. This is complemented by a diversified offer of wind turbines and towers. The current focus is on turbines in the megawatt range with varying levels of efficiency.
Albert Betz calculated already the maximum level of efficiency of 59.3% for wind turbines in 1919. Up-to-date models are achieving 80% of the calculated value from Betz. With that the level of efficiency of wind turbines is many times higher than of solar power plants.
Beside the level of efficiency, essential factors for the revenue of the wind farm are the tower height and rotor diameter. A tower height of approximately 100m in strong wind regions is already ensuring an attractive income. On low wind locations the wind revenues can be optimized with the right choice of wing design.
After choosing the wind turbine you will be also confronted with the question if you are willing to enter a long-term service agreement that is revenue dependent to minimize your own risks or if you prefer other solutions.
- Optimal wind turbines for inland, coastal and mountain landscapes
- Concept of the wind farm layout
- Wind turbines with or without transmission
- Pitch or stall controlled wind turbines
- Maintenance agreement or full service contract

The planning of a wind farm is also embedding an analysis concerning the foundation of the site. It has to be examined if the requirements for wind turbines on the site and access route are being fulfilled. If improvements are necessary it has to be arranged contemporary.
Another important point is representing the connection with the grid. Depending on the proposed feed-in quantities and the local conditions it can be close-by or further afar, which constitutes a substantial expense factor in the planning.
The decision if the area for the wind turbines, the transfer station and the cable route are going to be purchased or rented is also incorporating in the financial planning.
