Tailored support

Developing a wind project is a long process punctuated by key stages. Each stage requires specific in-depth skills.
True to the spirit of partnership that has driven us for 20 years, Vergnet supports its clients throughout the length of their wind project. Depending on the stage, this can be in various ways :

• - Our project engineering service can prepare preliminary studies. These analyses provide an overall framework to assess the feasibility of a project
• - We can point you to consultants or design offices in wind power, to produce detailed studies. This stage must be outsourced to confirm the technical and financial viability of the project for financial backers

Our fields of expertise

Size of wind farm, country of installation, financing... all these are parameters that impact the total timeline of the project. On average, a wind project in Farwind® regions develops over three to five years.

Our project engineers provide you with the following services :

1. Methodological advice

If you have never developed a wind project, you are not certain how to go about it or even to begin. Vergnet's 20 years' experience allows it to provide advice and expertise for the analysis carried out by the project promoter.

2. Preliminary wind farm analysis

Based on data provided by the client, whether based on specific measuring instruments or meteorological data (Vergnet does not install anemometers or collect data), our engineering teams process the data using specialised software and produce preliminary reports.

This quickly provides an initial assessment of wind patterns, including average, minimum and maximum speeds, and turbulence levels. This characterises the wind resource at the site, which is an essential first step.

For sites without anemometers, Vergnet can also provide satellite-based estimates if they exist in the database.

An important point to emphasise : Wind resource analysis must be carried out very accurately, by professionals, and with high-quality calibrated instruments. This is the longest stage in the development process, and poor methodology – although it will not prevent the project from progressing through its next stages – will end up being fatal when the project is presented to financial backers.

3. reliminary siting of the farm and calculation of effective yield

Based on the results of the preliminary studies from the previous stage, Vergnet uses specialised software to position its 275 kW or 1 MW turbines at the site.

To do this, the client needs to provide a topographical map of the area and the GPS coordinates of the site.

4. Calculation of project profitability

Once the energy resource has been fully characterised, it is possible to work out the project costs and the proceeds it will generate, calculate its profitability to assess its economic pertinence, and work on various parameters to maximise gains. For this, Vergnet uses, among others, Retscreen® software as well as internal models.
