Wind Power Generation Equipment

We inspect, troubleshoot, diagnose, and renew customers' wind farm facilities to keep them in sound condition. We also offer consulting proposals and 24-hour support services to maximize customers' wind power generatin portfolio profits through operational control and preventive maintenance.


  • Meidensha's services are provided by trained engineers who have expertise in the facilities and equipment. We will establish appropriate inspection cycles and parts replacement schedules. We engage in preventive maintenance based on accumulated data.
  • With the cooperation of our overseas partners, we can dispatch technicians equivalent in quality to those of wind turbine manufacturers.
  • In order that our customers can use their facilities with peace of mind, our technicians are available for dispatch anytime, anywhere, to provide high quality maintenance.
  • We can provide services on any scale. Please contact us for details.

Do you have any of these problems?

  • Do you have a wind turbine that is out of manufacturer's warranty period and in reduced service?
  • Do you have wind turbines that have not had blade inspection and repair for two years or more?
  • Do you need help with (spare) parts, procurement, import, repair, or maintenance?

All problems manifest themselves as a reduction in turbine availability, ultimately forcing shut-downs for extended periods of time and causing significant losses in power plant operations.
With our excellent technicians, worldwide procurement organization, and overseas subcontractors, we can handle any challenge our customers may face.
