What does a typical working day at the wind farm look like?

The working day of our servicetechnicians starts with the so-called “toolbox talk”, where the tasks and goals for the working day are discussed. The teams then travel to the individual wind turbines and work through the open points one after the other.

This may involve, for example, the maintenance or repair of various components of the wind turbine. But also the replacement of individual components or the inspection and quality control are on the agenda.

The issue of occupational safety is always at the forefront in order to protect our employees. Finally, we also ensure that the wind turbine is left clean and tidy.

Of course, this is only an example of a typical working day; depending on the project and often also the weather conditions, things can be different.

Why do you need a class B driver’s license?

The wind turbines are mostly not on our doorsteps. To be able to work in the windfarms it is important that you can drive a vehicle as your work locations are constantly changing. Therefore, it is urgently necessary to have a driver`s license.

Why do you have to be physically fit?

The work on the turbine is quite physically demanding, so you should be fit enough to manage the work. The wind turbines are often over 100 meters high and therefore also your workplace. Your physical fitness will be regularly tested by the occupational physician.

Why do you have to be “ready for assembly work” and what does that mean?

Assembly work means that you work in so-called “Work Turns”. Depending on the department and project, the length of these work shifts vary from 1-3 weeks. During the turns you are sleeping in hotels or in temporary accommodations. Since the wind farms usually have a long journey the work on assembly is necessary.

Why do you have to be able to work at heights?

In order to be able to work safely on a wind turbine, it is requiered that you do not allow yourself to be influenced in your tasks by great heights. To ensure your own safety and the safety of your colleagues.

What certificates are there in wind energy and which ones do I need?

Depending on the area of application, different certificates are required. In general, the guidelines are stricter abroad and on offshore wind farms, so you always need GWO-training there. Of course, you also have to regularly take an aptitude test with the occupational physician. In general, all the necessary certificates and training courses are financed by RTS.

What jobs are there in wind energy?

At RTS Wind AG, service technicians are basically in demand. However, they can have different qualifications, e.g. for electrical work, for mechanical work and for general work around the wind turbine. The service technicians work in our four specialist departments. Some of our employees also work as warehouse specialists for our customers. No wind experience is necessary for entry. In addition, there are jobs that require a lot of wind energy experience and go in the direction of quality inspection, occupational health and safety and wind farm administration as well as remote monitoring of wind farms.

Which professions are interesting for wind energy?

Generally speaking, anyone who is physically fit, able to work at heights and has manual skills can work at wind farms. The advanced qualification “Service technician for wind turbines” or “Specialist for the installation of wind turbines” does not require any specific vocational training.

However, trained electricians, electronics technicians, mechatronics technicians and mechanics have particularly good qualifications and are constantly being sought, as many of our clients require such training in order to work for them. In the rotor blade service, we welcome employees who have learned a trade related to surface coatings, e.g. carpenters, boat builders, fiber composite technicians, or painters and varnishers. We welcome employees from the rope access and industrial climbing sectors, as many areas of the wind turbine are not easily accessible and have to be reached “from the rope”.

What does the electrician in wind energy do?

The electrician/electronics technician (m/f/d) in wind energy, mainly takes care of the electronic work around the wind turbines.

This includes:

  • Electrotechnical service and maintenance work on wind turbines
    (e.g. transformer switchgear, generator systems, etc.)
  • Troubleshooting and fault elimination
  • Documentation of the work steps taken
  • Working with direct and alternating currents as well as low and medium voltages
  • Implementation of the high requirements for occupational safety

What does the mechanic in wind energy do?

The mechanic (m/f/d) in wind energy mainly takes care of the mechanical work around the wind turbines.

  • Mechanical service and maintenance work on wind turbines
    (filter replacement, grease maintenance, screw connection checks, visual and pressure tests, etc.)
  • Troubleshooting and fault elimination
  • Documentation of the work performed
  • Implementation of the high requirements for occupational safety

What does the rope access technician do in wind energy?

Maintenance work on the outside of the wind turbine and on the rotor blades is usually carried out by specialists who call themselves rotor blade service technicians, rope access technicians or industrial climbers. Because they are roped off outside at the plant using rope access technology. But there is also work from plattforms available, which don´t require rope access.

These specialists of height must also be well versed in surface coating, because the outer skin of the wind turbine is constantly attacked by weather and wind influences.

What does a service technician for wind turbines do?

The more wind turbines are built, the more technicians (m/f/d) are needed to maintain the turbines, repair them, install improvements and carry out the regular inspections during the operating phase.

The work is mainly done high up in the so-called nacelle and is carried out by skilled personnel with a mechanical (mechanics:inside) or electrical (electricians:inside) background. These are called service technicians for wind turbines.

How can a lateral entry into wind energy be successful?

Actually, anyone who wants to can get into wind energy. Wind energy offers a wide range of international jobs: Outdoors in the wind farms, but also in planning, project planning, administration and processing.

Those who want to work “outdoors” in the wind farms must be willing to travel professionally, be physically fit and have a driver’s license. In addition, a willingness to tackle manual tasks and to be outside in all weathers is indispensable.

Since the industry is young and has only been gaining in importance for a relatively short time, career changers from other industries have very good chances of gaining a foothold.

Just ask us and we will advise you on what your entry could look like.

General wind energy questions

How is wind energy generated?

The kinetic energy of the air currents is used to generate electrical power, which means that the wind turbines convert the kinetic energy of the wind currents into electrical energy. (source: https://www.interconnector.de/energieblog/funktionsweise-windkraftanlage-wie-windenergie-erzeugt-wird/)

What are the disadvantages of wind energy?

Wind energy is difficult to store and the construction of the turbines involves a lot of effort and high costs. Also, there is always a risk of birds colliding with the rotor blades.


What types of wind turbines are there?

There are basically turbine types for the sea (offshore) and for the land (onshore). Each manufacturer, however, builds its turbines slightly differently and is thus specialized for certain conditions of the environment. The amount of energy produced by a wind turbine is also called the yield. Each wind turbine should produce the best possible yield in the place where it is located. To do this, the wind turbine must utilize the power of the wind as much as possible. With the help of a wind survey, about the wind conditions on site, the appropriate wind turbine with the best yield is selected.

What is offshore wind energy?

Offshore means that a wind farm is located at sea. In this case, the wind turbines are installed on pedestals in the coastal apron. On the water, the wind is more consistent. As a result, a total of 7,794 megawatts could be produced by 1,500 offshore wind turbines in 2021. This puts Germany in second place in a European comparison. By 2030, enough turbines are expected to be built to increase installed capacity to 30 gigawatts. (Source: https://www.wind-energie.de/themen/zahlen-und-fakten/)

What is onshore wind energy?

Wind turbines that are located on land are onshore wind turbines. The installation and maintenance of these turbines is much less expensive than that of offshore wind turbines. They are an important part of the renewable energy supply, but provide significantly less electricity than offshore turbines. (Source: https://www.enbw.com/unternehmen/eco-journal/onshore-wind-pfeiler-der-energiewende.html)

How quickly does a wind turbine deliver more energy than was needed to build it?

The production of a wind turbine usually takes only a few months and can be realized with relatively low material and energy expenditure. After only a short period of operation, the energy expended is produced again. This period is called the “energetic payback time”. An onshore wind turbine needs between three and seven months for the energetic amortization. Offshore turbines with several megawatts of capacity need four to five months to recover the energy consumed during production and installation. After that, the turbines usually provide clean electricity for 20 years. Over its lifetime, therefore, a wind turbine can provide 40 to 70 times more energy than was expended in its production, use and disposal, depending on the design.

Which country is how strong in wind energy?

Worldwide, China continues to lead, followed by the USA, both in terms of total installed capacity and newly installed capacity. Germany is in third place in terms of total installed capacity. (Source: https://de.statista.com/statistik/daten/studie/37035/umfrage/windenergie-weltweit-im-jahr-2008/)

How reliable is wind energy?

Wind energy contributes the largest share of renewable energy in Germany. Almost 22% of gross electricity generation comes from wind turbines. So the turbines are definitely reliable. If this topic interests you, feel free to listen to this podcast episode:


What is the history of wind energy?

Wind was one of the first sources of energy and propulsion to enable the transport of loads. It was sailing ships that made long-distance trade, the discovery of America and the establishment of the country as a major maritime power possible in the first place. In the Middle Ages, wind energy was used in the form of windmills to grind grain or lift water. Since then, mills have steadily evolved so that we can now use them for our energy supply.

What is Germany’s wind energy share?

Germany generated around 117.3 terawatt hours of electricity from wind power in 2021. This corresponds to 20 percent of gross electricity production. (Source: https://de.statista.com/statistik/daten/studie/239528/umfrage/anteil-der-stromerzeugung-aus-windkraft-in-deutschland/)

How is a wind turbine constructed?

Essentially, the wind turbine consists of a foundation, a tower, a nacelle, a generator and a rotor. The three rotor blades are driven by the wind and transmit the energy to the generator (Source: https://studyflix.de/erdkunde/windkraftwerk-3695)

How do wind turbines work?

The way a wind turbine works is actually quite simple: to generate electricity, the wind is converted into rotational energy by the rotor blades of a wind turbine, which drives an electricity generator inside the wind turbine. The generator then produces the electricity that is used to power homes and businesses. Electricity production depends on wind strength, or speed. To be effective, wind turbines must be located in an area where there is a constant wind flow. Thus, the location of the wind turbine is crucial for efficient power generation. (Source: https://group.vattenfall.com/de/newsroom/blog/2016/august/energiewende-wie-funktioniert-windkraftanlage)

Are wind turbines a threat to birds?

In recent years, it has been shown that the risk of collision is very low. Many animals get used to the changed environment relatively quickly. As a result, birds and wildlife are hardly displaced by wind turbines. Most birds and bats fly around wind turbines. In addition, the height of the new wind turbine eliminates the possibility of collisions with most bat species. To avoid the tragic individual cases, habitats and populations are investigated in the vicinity of planned wind farms.
