Offshore Wind Accelerator (OWA) Tender: Mesoscale Wake Modelling

Call for entries from companies and consortia interested to undertake a study looking to understand the current landscape of mesoscale wake models available to the offshore wind industry.

There has been an increased interest in combining microscale and mesoscale models to better capture the total wake effect of a windfarm, and the effect of the wake at greater distances from the wind farm (the mesoscale far wake). However, the accuracy of both these ‘combined’ models has, generally, not been validated within the industry.

The impact of the mesoscale far wake is becoming increasingly important as more wind farms are built within close proximity to each other. This is of particular importance in the ever more crowded North Sea. It is key to better understand the impact of one wind farm on another so developers may have increased confidence in predicting the wake impacts from other projects.

The main objectives of this work are to:

  1. Review existing mesoscale wake modelling tools currently available within the industry.
  2. Identify suitable datasets for analysing farm to farm wake effects.
