Wind Insights

Identify key cost risks and energy potential

Top level statistics and diagnostic plots to evaluate wind conditions and other key cost differentiators.

Within the hugely complex data volumes of NWP models lie key parameters used to assess the attractiveness of wind farm leases.  Using multi-dimensional cloud techniques and web-based tools, TGS extracts the most important elements from these models and presents them clearly- turning a raw data volume into a dynamic top level wind assessment summary.  Now project investors can judge, compare and summarize wind characteristics including power output consistently over large areas with a single click reducing the time taken to reach conclusions and increasing the confidence of decisions made at the lease screening stage.




To emulate the core content of a formal lease assessment, Wind AXIOM provides critical diagnostic summaries of the wind resource available on-demand at any point, for all calendar months, and across all hub heights.

For each lease or point location, a 16 segment wind rose, daily-mean wind speed time series, hourly-mean wind speeds, vertical wind shear profiles, and annual-mean wind speeds are all available at a single click.

Wind AXIOM also summarizes key top-level characteristics, including long-term and monthly mean wind speeds, annual/monthly minimum/maximum values, annual/monthly standard deviation, and average days per month/year below cut-in speed or above maximum output.

Together, these insights build a detailed picture of the wind resource, underpinned by quality wind model data.

Idealized Power Output

No single value is more important to understand than a wind farm’s total power output potential.  Thorough net energy analysis and comprehensive loss factor modeling are critical for a bankable wind energy assessment- but at the pre-bid stage, some of these losses (for example external wakes and blockage) may not be well constrained.  At an early stage, it is important to be able to compare the potential of different areas using a standardized set of parameters. 

Using NWP model outputs and industry-standard methodologies, TGS computes a gross capacity factor for each project using the IEA’s 15MW offshore turbine.  Each wind lease’s total area is used to predict the number of turbines that can be sited in the lease, which then leads to an idealized power output calculation for any lease area of interest.  This allows project developers to quickly get an impression of the relative output (and therefore revenue) of all the leases in a bid round- or a comparison between different zone scenarios within a nominated government development zone. 

Constraining cost differentiators

Key physical environmental factors can markedly affect the attractiveness of an offshore wind project.  A zone with consistently high average wind speeds may still be prohibitively expensive to develop if the nearest onshore transmission line is over 100km away. 

To supplement wind model results TGS also presents datasets that constrain the key parameters that differentiate the most significant wind farm development costs. 

Separated into 4 additional map categories: transmission infrastructure, water depths, environmental zones, and marine space restrictions, Wind AXIOM clearly illustrates the impact of these issues on a lease or potential wind farm zone. 

To turn these maps into actionable insights IWA performs analysis against these parameters to present a summary of these cost differentiators with a single click. Further, Wind AXIOM allows tolerance profiles to be tested against potential leases or portfolios, flagging conditions where parameters fall outside of the desired range.

Finally, Wind AXIOM presents these results, including idealized power outputs, clearly for side-by-side comparison and further analysis- highlighting leases that are most attractive.

Share, Collaborate, Export

Wind AXIOM’s cloud-based infrastructure allows project sessions to be shared with collaborators from your organization or development group- enabling users located in multiple locations or organizations to connect with the same platform environment- a big workflow enhancement for those working with traditional server-based or offline databases.

TGS understands that compatibility with existing workflows is important- and thus supports flexible data export functionality including GIS, .wrg, and time series formats.  Also available are direct API service connections, including to all GIS layers and wind model maps, allowing seamless interoperability with existing platforms.
