A wind turbine requires a specific minimum wind speed, known as the “cut-in speed,” to begin rotating and generating electricity. This speed is between 3 and 4 meters per second (approximately 6 to 9

At low wind and rotational speeds the turbine generator will produce no power until the wind speeds reach the required cut-in speed for that particular wind turbine.
