VENTOTEC offers many years of comprehensive knowledge in planning of wind park projects. In order to implement wind park projects successfully it is necessary to clarify important details at a very early stage. Only on optimal sites and with enough wind do projects provide the necessary yield.
Each project begins with an idea: The desire to build wind turbines in a particular area.
The first step of assessment is evaluating the site. Not every desired site is suitable for future generation of wind energy. Key issues are wind conditions, availability of infrastructure, requirements of nature conservation and last but not least local acceptance of a project.
We determine the possibilities: The application of geo information systems allows us to determine existing potential for utilization of wind energy on a large scale.
We analyse the wind potential, requirements made by planning legislation, consequences of emission control regulations as well as suitability from a species protection point of view for each site in question.
The results of the site evaluation allow us to make a statement to whether or not a site is suitable for erecting a wind park in particular under consideration of technical, legal and economic aspects.
One of the most important steps in the process of planning is securing land from a civil and planning legislation point of view. Prior to contacting with local municipalities or land owners, a site analysis based on site inspection and further research encompassing the following aspects takes place:
Selection of a contractual model: lease per turbine site vs. lease per m²
In order to economically analyse a wind energy project we calculate the average wind speed and the expected annual energy yield for each site. The calculation is based on various types of wind turbines and hub heights. Depending on the available data basis we conduct the analysis in two different ways:
In both cases a consultant evaluates the results and defines the uncertainties linked to the site. Possible yield losses due to restrictions of operation such as full or partial shutdown due to noise and shadow flicker and for the protection of birds or bats etc. are also taken into consideration.
Ensuring a basis on the grounds of planning legislation is done parallel to securing land required for a project. The level on which wind energy is regulated varies within Germany: Partially a regional development plan sets the frame; in other cases local municipalities have freedom of decision.
The local municipality is always our first and most important reference point! Discussions with the administration and the municipal council lead to a mutual development and inclusion of the wind park area in the regional development plan or the urban land use plan. Planning instrument for the implementation is an urban management contract between us and the local municipality. This contract regulates mutual responsibilities in regard to the drafting of a land development plan and often also the use of land and infrastructure such as roads belonging to the municipality for the wind park.
