• Tawanai's in-house Wind Resource and Uncertainties Assessment software.

• Use of Gaussian Wake Model validated against Large Eddy Simulation data. Uses principles of conservation of mass and momentum which form the basis of computational fluid dynamics.

• Unlike standard non-cfd flow models, our wind flow model is highly data intensive and its semblance with fluid dynamics based analysis has been internally validated. Furthermore, based on the complexity of terrain we are able to capture data at finer resolutions for greater accuracy.

• Our Orographic analysis schedule is extremely useful for purposes of micro-siting. By identifying locations with the least orographic resistance, we are able to identify the best locations in a given region.

• Intra and Inter windfarm location optimization. We are able to simulate the wake model at different permutations and combinations of the layout in order to maximise both internal and external array efficiency.

• Does not assume a wind-speed distribution, rather simulates for each timestamp.

• 10/15/60 minutely Gross and Net generation figures for each wind turbine. Hourly P75 time-series for each WTG in a proposed windfarm can be extracted and the output can be combined with solar assessments for a Wind-Solar Hybrid analysis.

• For long-term correction, our software makes use of a customized gradiant boosting regressor to model the relationship between several weather parameters. Once a strong correlation at hourly levels is established on Test Data, we use the trained model to predict 10-20 year wind speeds at hourly levels. As a standard, we ensure that the model achieve an R-square value of at least 80% on Test data.

• Extensive coverage in Losses and Uncertainty Calculations.

• Over the last two years, Tawanai has undertaken 12000 MW of WRA exercises for different Clients.
