I managed to find out the details of the Power Boost function.
Q: The turbine can be adjusted to produce 15 MW with Power Boost. Can you explain how?
A: The Power Boost function is a wind turbine control feature that increases (boosts) power based on real-time monitoring of the site-specific conditions. For turbines equipped with Power Boost, this functionality is always active. However, if for example the wind speed reaches storm levels, or the turbulence level exceeds a certain limit, Power Boost is deactivated, and the turbine returns to normal power. What we have seen in our fleet analysis is that the Power Boost feature is active more than 98% of the available time, and thus ready to produce up to 15 MW power for this turbine.
