Vaisala Releases New Ecofys Verification Studies of Triton Remote Sensor
Studies by leading wind energy consultant demonstrate excellent consistency and performance

VAISALA CORPORATION                         PRESS RELEASE                                  NOVEMBER 15, 2016

Vaisala, a global leader in environmental and industrial measurement, has released two independent verification studies conducted by Ecofys, an international consultancy based in Europe recently acquired by Navigant. The studies used two production Triton units deployed from March 5 - May 29, 2015 and June 6 - Sept 10, 2015, respectively, at the Lelystad test site.  

The verification studies include an assessment of the sensitivity of the Triton remote sensor to environmental factors, demonstrating that wind speed measurements taken by the unit are unaffected by changing environmental parameters. Rather than using the minimum amount of data required, the studies were conducted for a time period of several months, ensuring a more robust, representative dataset with which to assess measurement uncertainty.

The wind energy industry's ability to predict and assess a project's annual energy output is a crucial factor in securing and maintaining investor confidence in wind projects. Triton, a ground-based SoDAR remote sensing system, is used to measure wind at and above the hub height of today's taller wind turbines. By supplementing or replacing measurements from met towers in resource assessment and operational settings, Triton adds value and provides a cost-effective solution to wind developers and operators.

The Ecofys studies are part of Vaisala's commitment to quality and program of continual improvement to support wind power plant developers and system operators in applications ranging from early stage prospecting to repowering legacy power plants.

Triton is the industry's leading remote sensing system with over 17 million hours of wind data collected in over 80 countries since 2008.
