Wind Measurements
Measurements on site are important to ensure the wind farm development has the expected wind climate. We have a long, +20 years, track record of installation, operation, maintenance and monitoring of wind measurement devices such as Masts and LiDARs for more than 50 clients.

Measurement masts
Installed 174 m met mast in Bergö island measuring for planned Korsnäs offshore wind farm
Since 1998, we have designed and delivered more than 250 bankable turn-key measurement campaigns for planned wind farm projects. We can take care of the complete process from permit application to operation and monitoring until decommissioning depending on the needs.
All masts installed by us comply with the latest international standards and best practices such as IEC 61400-50-1:2022 (replacing the more known IEC 61400-12-1:2022).
We have experience from measurement stations in Norway, Sweden, and Finland in addition to several projects outside Scandinavia, from Svalbard to Antarctica. We offer optional technical availability guarantees for our measurements for our clients to ensure maximum campaign reliability.
We install tubular- and lattice masts, and have made installations in existing telecom masts. To ensure a minimum of influence by surrounding structures it is recommended to use masts specifically designed for wind measurements.
Our field group has long experience from building and installing met masts, and from installing and operating wind measurement equipment. We highly prioritize HSE and our personnel are skilled and certified mast climbers.
Remote Sensing: LiDAR
Lidar installation complete: (left) mobile power supply, (bottom) solar panels and (right) lidar
We have also worked extensively with LiDARs remote sensing devices and we have delivered more than 50 bankable LiDAR campaigns onshore & offshore to date in Northern Europe. Since 2009, we have offered turn-key measurement campaigns of ground based LiDARs. We have experience with scanning and profiling LiDARs from Vaisala (Windcube V2.1, Windcube400s) ZX LiDARs (ZX300) as well as the support and operation of the devices. We also provide services for devices owned by our customers. We follow the latest standards such as IEC 61400-50-2:2022 for compliance regarding LiDAR classification and verification to minimize measurement uncertainties.

Expertise in measurements in icing climates
For wind farms in cold climates, production losses due to icing may increase the uncertainty for the wind energy yield.
Kjeller has experience in installing mast and measuring devices in cold climate sites with the aim of maximizing the yield while still maintaining a high quality of the measurements. We can propose suitable heating setups depending on the location and the potential icing expected.
In addition, we have many years of experience with measurements of ice with a variety of ice sensors.
Measurement Strategy
A clear and well thought through wind measurement campaign strategy providing a plan for measurement device/s deployment across the site will decrease uncertainties in an energy yield assessment and increase cost effectiveness. Our wind campaigns are designed by both engineers and wind analysts to minimize uncertainties for energy yield assessment.
