Introduction
ENERCON provides advanced technology for wind energy sites at risk of ice formation, ensuring safe, efficient, and reliable operations. This document outlines the ice detection and blade heating systems developed by ENERCON to mitigate the risks associated with ice formation on wind turbines.

Ice Detection System
All ENERCON wind energy converters come equipped with a standard ice detection system based on a patented characteristic curve analysis method. This system compares current operating data with long-term mean values to detect ice build-up, which alters aerodynamic properties and stops the wind turbine. The system determines thawing time based on outside temperature, and turbines can be manually restarted after visual inspection if automatic restart is deactivated.

Blade Heating System
The ENERCON blade heating system is a cost-effective solution to reduce energy loss due to icing. It features easy maintenance, no increased risk of lightning strikes, and energy consumption ranging from 46 kW to 225 kW. With over 20 years of experience and more than 3000 installations worldwide, the system has proven effective in reducing icing-related yield loss.

SCADA Power Consumption Management
ENERCON's SCADA system allows for the restriction of power consumption at the network connection point, minimizing additional costs from large electrical consumers like the blade heating system. This is particularly beneficial when turbines are at a standstill.

Risk Minimization
ENERCON has developed software certified by Deutsche WindGuard to evaluate risks of ice shedding and ice throw. Optional ice warning lights and site-specific strategies further minimize risks during wind farm operation.

Cold Climate Package
For sites with extreme cold conditions, ENERCON offers a Cold Climate package that includes modified components for reliable operation at temperatures as low as -40°C. The power curve remains unaffected down to -30°C, with power reduced linearly below this temperature.

Conclusion
ENERCON's technology for sites at risk of ice formation significantly reduces downtime and yield loss, ensuring efficient and safe wind energy production even in extreme climates.
