Most wind turbines need a minimum wind speed of about 7 to 11 mph (3 to 5 m/s) to start generating electricity. This threshold, called the “cut-in speed,” is the point where the blades begin spinning fast enough to produce usable power.
Prices commonly fall between about $1,800 to $8,000+ depending on facility size, electrical distribution complexity, and whether a detailed arc flash label package is included.
