Vaisala is providing measurement systems and services to Finnish wind power company, Puhuri Oy, which operates three wind projects and is developing several more in Finland. The agreement includes two Vaisala Triton Sonic Wind Profilers, which will be installed in northern Finland, as well as an annual SkyServe maintenance and data management contract. Furthermore, Vaisala will deliver the planning and wind resource evaluation services as part of the measurement campaign to help Puhuri better assess the performance potential of its proposed wind farms.
Puhuri selected a maintenance-free solution, well suited for cold climate conditions. Toni Krankkala, Project Director with Puhuri explains that on-site measurements are necessary to truly understand localized wind conditions, “It is important to get a reliable picture of wind characteristics in a region as quickly as possible. In a measurement campaign it is easiest to start with a lightweight and mobile measuring device. If the results turn out to be promising, we can confidently make additional investment in the site with longer-term measurements and the installation of a meteorological mast.”
Puhuri selected Vaisala as their supplier following careful evaluation. Krankkala says, “The Vaisala Triton has a proven track record as being a reliable, easy to use, and maintenance-free solution with extensive cold climate experience. In addition, its low power consumption, and the option of using a fuel cell or a solar panel to recharge the battery, means fewer visits are needed to the measuring site. This is important, as the locations we are studying are remote and difficult to access, particularly in the winter. Finally, the SkyServe service is very user friendly, and it provides near real-time information on the measurements.”
The Vaisala Triton Sonic Wind Profiler is a SoDAR system that provides accurate wind measurement data for wind resource assessment and wind farm operations. The Triton accurately measures wind speed and direction across the full rotor sweep of a wind turbine. The technology behind the Triton was specifically designed for the commercial wind energy industry. Triton provides hub height wind data, which allows wind developers to optimize project financing packages and operators to gain valuable information about conditions that may impact current performance at existing wind farms.
