Virtual Met Mast™ can help wind farm developers and wind farm consultants select the best onshore and offshore wind farm sites anywhere in Europe.

It provides key wind climatology statistics including mean wind speed, wind direction, exceedance values, air density, wind shear and turbulence intensity, which are demonstrated in our sample report (PDF, 1 MB) .

Virtual Met Mast Plus™ is an enhanced option of Virtual Met Mast™. It combines Virtual Met Mast™ wind estimates with on-site mast observations to provide revised wind statistics at higher levels of confidence.

Benefits for wind farm developers and consultants

• Fast and accurate site screening solution.
• Increased certainty of long-term wind resource prior to installation of real met mast to support site selection.
• Time and cash flow savings by delaying investment in real met masts.
• Accurate wind assessments in areas where no reliable wind data is available.
• Quicker decision making - receive wind resource estimates in days rather than months.
• Lower due diligence costs to benefit smaller wind projects.
