Zug, Switzerland – November 8, 2018 – Innovative iSpin technology selected to monitor the performance at Vattenfall’s European Offshore Wind Deployment Centre

11 Vestas V164-8.4 MW turbines in Vattenfall's  European Offshore Wind Deployment Center (EOWDC) in Aberdeen Bay, Scottland, have been provided and equipped with the iSpin technology and measures the site wind conditions since commissioning in August 2018. The iSpin equipment will help Vattenfall understand the performance and any changes to the performance of all the wind turbines, as well as give them the opportunity to improve the performance of the wind farm.



Paris, France – February 12 2018 – iSpin to be installed on an entire wind farm, owned by Zephyr Energies Renouvelables (France).

After successfully running a demo project on a first turbine within the wind farm La Renardière (Loire-Atlantique), the operator Zephyr Energies Renouvelables will now deploy the iSpin technology on the whole wind farm. Made of 6 Senvion MM92 wind turbines commissioned in 2010, this wind farm will be the first one in France to be entirely equipped with iSpin.

29 September 2016: iSpin Guardian approach provides transparency in wind farm performance monitoring

ROMO Wind’s iSpin Guardian approach allows wind farm operators to monitor and actively manage the performance of every wind turbine in a wind farm at any time during its lifetime, independent of site complexity. The iSpin Guardian approach, which uses patented spinner anemometer technology, allows operators to compare the performance of individual turbines in a wind farm for the very first time. ECN (Energy research Centre of the Netherlands) has evaluated the approach.

22 September 2016: Thüle wind farm: 3% more production through wind measurement at the spinner – iSpin technology detects yaw misalignment

The patented iSpin wind measurement technology has been installed on two of the Vestas V80 turbines in Energiekontor’s company-owned Thüle wind farm, enabling wind measurement directly at the spinner. The result of the measurements: both turbines were affected by yaw misalignment of 8 degrees, and after correction on average 3.2 percent more production could be achieved. Now the wind farm operator plans to equip further turbines with the iSpin system.

24 May 2016: Vattenfall and ROMO Wind publish performance data verifying that iSpin technology accurately measures wind farm performance

Danish-Swiss wind turbine optimiser ROMO Wind together with Vattenfall carried out a performance measurement project at Nørrekær Enge wind farm in Denmark using 13 Siemens 2.3 MW turbines. The goal was to compare the power curve measurement results of an IEC-compliant met mast, a nacelle LiDAR, and the iSpin spinner anemometer. The results show that only the iSpin technology enables reliable and replicable wind turbine performance measurements on all turbines in the wind farm. Within a confidence interval of 95%, the comparable wind turbines were observed to be operating within only 0.3% of AEP to each other and the power curve verified reference turbine. The raw measurement data is available in an online data sharing portal and interested experts are invited to analyse and confirm all data and results.

03 February 2016: Spinner anemometer technology can now be used to measure power curves in accordance with IEC standards

The spinner anemometer technology of Danish-Swiss wind turbine optimiser ROMO Wind can be used to cost-effectively measure the power curve of every single turbine in a wind farm. This has now been confirmed by the International Electrotechnical Commission (IEC), which has published a new clarification sheet. The document describes the calibration procedure for norm-compliant use of the precise patented measuring technique directly at the spinner of a wind turbine.
