As an emerging industry, questions and concerns often arise surrounding proposed and operating wind energy projects.

This information is designed to give answers to common concerns and frequently asked questions. Facts and figures from

independent sources were used to support the information.

LIGHTNING

It is very rare that lightning will strike a wind turbine.


On the rare occasion that a wind turbine is struck, by lightning, the turbine is grounded to protect the structure. Parts of the grounding

system are built into the wind turbine blades, nacelle and tower. In addition, a buried grounding system is constructed as part of the wind

turbine foundation pad. The electrical components of the equipment have surge protection to limit lightning damage. Proper setbacks

from heavily trafficked areas and residences, serve to protect people from such rare occurrences as lightning strikes.
