You are not telling the complete picture either. Please indicate the cost of the increased transmission capacity. Please provide an overall cost figure than includes the windmills, extra transmission capacity, complex control systems, and backup capacity. When the complete system cost is included, wind power is very expensive.

As indicated in the linked article, the cost of this two point connection, which Texas PUC chose to go with, was $5 billion, which equates to a $4 dollar per month cost to the Texas rate payer.

The single point connection was $3 billion and the three point connection(with Houston being the third point) was $7 billion.

As for the cost of the windmills, those are the cost of the generator and are paid for/amoritized in his selling price.

I'm not sure what you mean by controls except to say that these would be included in the cost attributed to the wind farm operator, the transmission line builders, or the local provider, which, in the case of the two point connection, was Oncor.
