Fresh wind knowledge
Technical expertise coupled with creative potential typify our technical operations management and engineering services as well as the work of our team in the control room.
Technical operations management
European portfolio
We specialise in the technical operations management of generation units from wind and photovoltaic renewables, transformer stations and storage systems. Our European portfolio comprises an output of around 750 MW and 360 plants from a wide range of manufacturers.
High quality standards Our internal quality and process management enables us to work in a standardised, highly professional manner. We annually review this high quality standard in internal and external audits.
We provide impetus for innovations in system operation, operational optimisation and the implementation of technical upgrades. The expertise of our employees enables us to assume responsibility as a system operator in accordance with DIN VDE 0105-100.
Continued operation and repowering We also support clients in the areas of continued operation, repowering and the implementation of legal changes based on the latest findings.

Technical optimisation of wind turbines
Special field: rotor dynamics
Investing in professional, periodic balancing of the rotors of wind turbines over their entire service life saves many times the costs that would otherwise be incurred due to unbalance-related damage and loss of yield. Balancing thus significantly reduces the electricity generation costs and lifetime consumption of wind turbines, both onshore and offshore.
As specialists in engineering services for the technical optimisation of wind turbines, we focus on balancing, blade angle measurements, customised measurement campaigns as well as expert reports and consultation services. We get the very best out of the systems through root cause analysis, fault analyses, measurements, inspections and rectification of identified problems.
Our clients can rely on short distances, direct contact persons and fair conditions, and we act independently and autonomously for the entire German and international market. Our specialist field: rotor dynamics!
Blade angle
Using photogrammetry and vibration measurement, we identify blade angle deviations with an accuracy of 0.1°. In this way we ensure that your wind turbine can achieve the promised yield. In addition, harmful vibrations are reduced to maintain component service life.
Balancing
We can balance affected wind turbines with a high degree of accuracy as well as perform low-cost, suspicion-free inspections of entire wind parks to identify affected turbines in the wind park. After balancing, your wind turbine runs smoothly again. Harmful vibrations are reduced to a minimum so that components work durably and reliably.
Special measurement campaigns
Do you have special requirements, and are you looking for a dedicated team of engineers to realise them? We’ll find a solution for you!
Video-based measurements
We use video-based measurement methods to directly record various movements of a system, and we can carry out customised analyses: these check deflection and torsion of blades during operation, tower movements during setup and operation and, of course, the vibration level of the system.
Technical consulting
We perform root cause analysis for component- or entire structure failures with e.g. foundations, towers, machine supports, drive trains, hubs, rotor blades and adjustment mechanisms.
Expert reports
As independent experts we assess projects from the foundations to the rotor blades, covering all relevant issues.
At a glance:
- Blade angle measurement
- Vibration-related blade angle validation
- Rotor unbalance testing (qualitative)
- Rotor unbalance measurement (quantitative)
- Video-based rotor unbalance test (qualitative)
- Checking of natural frequencies
- Checking of wind tracking
- Tower clearance measurement (during operation)
- Blade twist measurement (during operation)
- Measurements on small wind turbines (SWT)

24/7 monitoring onshore and offshore
independent. intelligent. inspired
We specialise in 24/7 monitoring of wind turbines, transformer stations, cable systems and offshore platforms.
Certified according to ISO 9001 and ISO 45001. In preparation: ISO 14001, ISO 55000 and ISO 27001
In our independent service control centre, we monitor wind parka and photovoltaic systems around the clock. We can already remotely process a large number of fault and error messages without the need for an on-site service team. We liaise closely with your service and maintenance provider and arrange the necessary services on your behalf.
We coordinate all necessary registrations and deregistrations and also assume responsibility for the system if required. The documentation of all service measures and customised reporting to you or your technical operations manager are part of our service. This ensures optimum operation and makes sure of high system availability. Increasing system sizes/performance classes require the registration of necessary service deployments with the service providers, and the actual coordination and planning of these deployments by the service provider must be continuously traceable.
Thanks to our detailed error analyses and error statistics, we can quickly identify vulnerabilities and work closely with your service providers to develop specific measures for improvement.
The highest safety standards apply to greenwind control. All data is stored on servers in Germany. Regular data backups are carried out on locally separated and redundantly secured servers.
Technical data
- 24/7 staffing by qualified personnel specialising in electrical and mechanical engineering consistently guarantees expert direct advice in the technical support line area
- Proven technology and software from the industrial sector for monitoring grids and generation plants, reliable and tried and tested in practice
- Visual diversity thanks to large screens and workstation monitors as well as separate visual and acoustic signalling systems (fault messages)
- Connection to supervisory control systems via various interfaces (e.g. database protocols, IEC 104 standards and OPC standards)
- Own development unit that individually integrates projects and can realise customer requirements in close coordination (development environment available on the software side)
Safety first
- All data on servers in Germany with regular data backups on locally separate and secure storage facilities
- Switching operations and preparation of switching instructions possible (extension of access rights)
- The greenwind system can be easily disconnected at any time to ensure undisturbed monitoring by the client’s systems (prioritisation, bandwidth limitation)
- Regular training and sensitisation of greenwind control managers (and also contractual partners); adapted control system to monitor compliance with safety standards
- Dynamic implementation of security regulations (internal and external, including Federal Office for Information Security whitepaper, critical infrastructure regulation, data protection requirements of the Federal Data Protection Regulation) and selection of external suppliers with IT security management systems
- Building and room protection
