Wind Farm Maintenance Services


Reliability Centered Maintenance

Reliability centered maintenance for scheduled services, trouble shooting, and minor correctives.


In wind farm operations, Reliability-centered Maintenance (RCM) is an advanced strategy used to optimize reliability, production, and asset life for wind farm owners. RCM emphasizes the use of Predictive Testing and Inspection (PT&I) techniques in combination with traditional reactive, preventive, and proactive measures to determine the optimum tasks based on the consequences, costs, and safety risk.

Wind energy becomes more cost effective when the costs of building the projects or operating the projects are reduced. On the operations side, cost reductions are achieved through building a reliability centered maintenance program for these projects. A key element to building a reliability centered maintenance program is utilizing many different data sets such as parts usage, parts age, production, parts condition and failure causes.                                                                

Scheduled Services

Regularly scheduled maintenance and service are necessary to keep and maintain the WTGs and WTG equipment in good working order including, but not limited to, periodic bolt torqueing, inspection, testing, lubrication, testing and other overhauling of the tower, nacelle cover and bedplate, blades, transmission system / drive train, yaw system, hydraulic system, control box, WTG mechanical and electrical equipment, all of which shall be performed in accordance to published maintenance recommendation from the OEM, or as amended by technical bulletins.

Scheduled maintenance services include the following:

  • Hydraulic system adjustments.
  • Topping off of fluids as determined by inspection.
  • Gear box oil sampling, testing and extractions.
  • Filter changes when required.
  • Visual inspections.
  • Preparation of standard operations and maintenance reports.
  • Management of preventative maintenance consumables.
  • Greasing of specified greasing points                                                                                                                          

Trouble Shooting

At UpWind, the Engineering team is responsible for monitoring the performance and providing root-cause analysis and troubleshooting of 5,000 MW of wind turbines, including the GE, Gamesa, Acciona, Vestas, and Clipper wind turbines. The diversity of technologies provides a wide range of experience on hydraulic and electric pitch systems, generators, converters, yaw drives and all failure modes on every gearbox model

Our experienced troubleshooters develop additional training programs and Job Performance Measures (JPMs) for recently hired technicians, providing a clear path of success for all of our managed sites.                                                       


Maintenance and service is necessary to keep the WTGs and WTG equipment in good working order.  This includes initial troubleshooting, unscheduled lubrication, consumables/wear parts and minor repairs to all WTG components, including general housekeeping and cleaning of the WTGs and equipment:

  • Local resets, inspections, emergency and non-scheduled events.
  • Resets not resulting from an Operating Force Majeure Event.
  • Troubleshooting and recommend corrective action.
  • Inspection, maintenance and services summary reports for each WTG on an agreed to periodic basis.
  • Replacement of spare parts other than Major Component Repair and BOP.
  • Review possible ways to drive down inspection, maintenance and services costs.
