In doing some research I have come across about 10 or so manufactures worldwide that build wind turbines. None of the sites that I looked at had any real cost data on the purchase of a new wind turbine. Does anyone know the ball park purchase price of mid-range wind turbines? Turbines in the 250kw -500kw range. Also is there a list of manufacturers anywhere?

Would appreciate any and all advice….

My understanding is that this is a very difficult size of turbine to procure right now, especially in the U.S., so that might be part of why cost data is hard to come by.

One of my co-workers has heard about a 100kW machine that should be available soon that will probably run somewhere between $300,000 and $500,000.

Here are some places that might be helpful to look for more information:
