Wind Turbine Data Analysis and Performance Assessment

Realise Energy Services can retrofit state of the art supervisory control and data acquisition software (SCADA) and turbine control solutions which enable better monitoring and operation of turbines – ensuring more consistent performance and availability.

A comprehensive data analysis process enables us to accurately monitor and evaluate turbine efficiency and availability, by producing graphical and numerical comparisons across the fleet of turbines which we maintain.

Our engineers are trained to analyse power curves and make site specific adjustments to ensure that turbine performance and availability is optimal for your site.

Grid Fault Analysis

Resolving grid quality issues that might affect turbine performance.

A weak grid can result in significant downtime and increased wear on turbine components.
We use fault analysis to analyse the quality of the grid connection and incoming supply to the turbine. Realise Energy Services are able to liaise with the Distribution Network Operators on your behalf and assist in resolving grid quality issues that might affect turbine performance.


Realise Energy Services can offer a range of other services and new technology to improve availability:


  • Preventative maintenance – e.g. blade cleaning and re-coating
  • Blade pitch adjustment and calibration
  • Anemometer and wind vane calibration
  • Installation of correct cables and components
  • Cable condition inspection
  • Moving meter positions
  • Changing parameters to suit site specifics
  • Upgrading controllers and software
