Wind Energy Project Feasibility

Prospecting & Resource Assessment

The "fuel" of a wind project is the most critical factor driving its commercial success or failure. Where is the wind strongest? How much year-to-year power variability is expected? What are the exceedance values at the site? Without answers to these questions, it is impossible to assess a project's feasibility or manage your exposure to risk. 3TIER accurately answers these questions anywhere on Earth.

Quickly Explore Wind Resources Around the World

Save time and money by targeting the best locations for wind energy projects and infrastructure. 3TIER lets you quickly explore any location around the world directly from your computer. Now you can avoid problem sites and separate successful projects from marginal ones earlier in the process. Our on-demand, initial wind resource assessments are based on a consistent, global dataset so you can compare sites with confidence.

Maximize Accuracy With State-of-the-Art Science

Direct measurements are the best way to record actual wind conditions and the unique terrain effects at a site. However, it takes 10+ years to capture climatic variability, which can make or break a project financially, and few measurement campaigns have records extending that far back in time. To mitigate this risk, 3TIER uses on-site measurements to correct our long-term simulations of site climatology with advanced statistical techniques. The result is significantly reduced uncertainty about future project performance and the bankable production estimates required to secure project financing.
