Estimated power production for the Evansville wind turbine based on the Maine Northwind 100 turbine actual production, both are class 2 wind areas.
A Northwind 100 turbine can produce 24oo kw of electricity in one day at 100% capacity factor.
This is day # 289 this year.
289 days at 2400kw = 693,600kw at 100% capacity factor
The Maine turbine has produced 50,391 kw in 289 days or 174 kw per day on average.
The Maine turbine is producing power at a capacity factor of 07%.
If the Evansville turbine is able to produce a similar amount of power it would produce 63,510 kw in one year.
At $0.10 per kw the Evansville turbine will produce $6,351.00 of electricity in one year. I doubt that Evansville pays $0.10 per kw so this figure could be high.
Now you would have to deduct the cost of the maintenance agreement, the insurance policy, and any interest payments if the money is being borrowed from the $6351.00.
Even if there were no deducts from the $6351.00 it would take 75 years to pay back the $480,000 initial cost of the turbine that has a service life of only 20 years. Evansville is getting some grant money for this turbine and I don’t know what their out of pocket investment will be but as tax payers and rate payers we are on the hook for the total $480,000.
If the turbine salesman is projecting $14,000 of electricity per year he should back it up with a guarantee, and pay the difference between what is actually produced and the estimated $14,000.
Things in Evansville must be very good if they can consider this large investment for a novelty item in these exceptionally hard economic times.
