I don't know what those mills put out... but most that have been put up in this area are in the 1-3 MW range depending on the wind available. The last numbers I heard is that they were somewhere in the million per MW cost to erect. Mabey somewhat more per unit of electricity for a smaller unit. It seems to me that the last coal plant they built here 20 years ago was about in that range... and they're still feeding coal into it.
The biggest problem with wind is not the cost of erecting the machines. It's maintain a parallel infrastructure for backup when the wind doesn't blow. They also do not want to pay a reasonable amount of money for the wind energy (at least here)... so yeah... they probably need a subsidy to make it work. Seems like the utility will pay mabey 3 c KW-h vs charging 10.5 c KW-h for said energy to their customers. That's a tidy profit for transmission if you ask me... particularly given that they spend buggerall on maintaining that infrastructure (that the government paid to install in the firt place). Wind could be a lot more viable IF they can work more sensibly to plan some reliability into the system.
