Operation and Maintenance

Operation and Maintenance

The importance of regular servicing

Medium scale wind turbines (100-900Kw) supported by the FiT or ROC incentives need to maintain high levels of availability to ensure cash flow and overall project returns are viable over their entire lifetime.

An incorrect or weak maintenance regime can lead to a variety of problems including:

  • A loss of availability, efficiency and production
  • Safety issues, e.g. vibration related electrical damage/fire hazard
  • Increased noise and non-adherence to planning conditions
  • A lack of insurance cover

Regular wind turbine servicing increases yield and ensures optimal return on investment.

Farm Energy NI’s sister company, Realise Energy Services, follow manufacturer’s recommended service protocols to ensure turbines are kept in their optimum condition and that any issues are identified early. This prevents bigger issues and even bigger costs occurring in the future.
