Yes. However, at times you will see the windmill not spinning because of required maintenance or too much or too little wind. The wind speed needs to reach 12 miles per hour for the generator to engage, produce power, and spin the blades.
The turbine operating functions are monitored remotely at Avant Energy’s Minneapolis office. As issues arise, they are handled either by sending a signal to a controller to change an operating function or by dispatching a maintenance service provider to the turbine to correct the problem.
Under normal operation, it should not make noise. However, if a spoiler does not retract, it can cause a loud noise. The noise will persist until Avant Energy is aware of the problem. Avant Energy is considering establishing a fault notice and/or alarm, should a spoiler not retract, which would be sent to the Minneapolis office.
