ROMO Wind is the independent and exclusive provider of the unique iSpin system, a revolutionary approach to wind measurement.

The iSpin spinner anemometer measures the wind where it makes sense: in front of the rotor at the spinner, where the wind first hits the turbine. Our goal is to provide you with better insights to ensure that your turbines reach their full potential. By measuring all the significant wind parameters, iSpin can help you with wind power optimisation, avoid unnecessary loss and even extend the lifetime of your wind turbines.

The iSpin advantages at a glance

Performance monitoring

With iSpin, you will be able to verify and optimise the efficiency of your wind turbine by monitoring the power curve. iSpin lets you know when acute and chronic influences are impacting the performance.

Higher yield

With iSpin, you can increase the productivity of your wind turbine. iSpin identifies and helps you with wind turbine adjustment. It helps your turbines reach their maximum potential.

Lower loads

With iSpin, you can increase the life of your turbine by reducing loads. By measuring and calculating yaw misalignment, wake sectors and much more, you can improve your wind farm management. You can profit from shorter down-time and lower maintenance costs.


The power of iSpin in detail

iSpin uses ultrasonic frequences to measure and calculate all relevant wind parameters. Using the measurement abilities of iSpin allow uniquely deep and accurate wind condition insights.

Benefit from a win-win partnership with ROMO Wind

Get the iSpin system and optimise your wind turbines

Every wind turbine should tap its full production potential.

With iSpin you get the highest data quality at the lowest competitive price.

In return you get installation and calibration, data collection, regular reports, analysis and alerts, and service and maintenance of iSpin. The best thing is that the additional yield, which can be generated by correcting yaw misalignment, can more than cover the service fee.


"Using the iSpin technology prevented us from deploying a met mast on that site, while at the same time still getting independent measurement on all turbines, and for a cost that would have only allowed us to equip one turbine with competitor’s technologies."

Simon Brillet, Technical Director at Valorem

"The measurements taken with iSpin provided us with an annual additional yield of 275.000 Euros, with the 19 turbines producing on average 182.500 kilowatt hours annually"

Dr. Claus-Eric Gärtner, Managing Director of BVT Windpark Sustrum/Renkenberge

"When using the spinner anemometer on one of Vattenfall's wind farms in Denmark we measured a significant improvement of the annual production of approximately 2.5% after ROMO Wind had corrected yaw misalignments in more than half of the wind farm turbines"

Anders Sommer, Senior R&D Engineer, Wind Power at Vattenfall R&D

"iSpin provides more accurate measurements than the nacelle anemometer and will in our opinion be an important technology to understand and increase performance on wind turbines"

Francisco Galván González, Technical Director Europe of EDPR

"ROMO Wind's calculations of the magnitude of energy loss caused by yaw error are confirmed by DNV GL calculations"
