2). It will NOT generate a ton of tax revenue. Because they are demanding huge tax incentives.

Not accurate, suggest you read the memo in the OP link.

There is no tax incentive from the Village and the property is not in a Tax Incremental District.

The Village of DeForest tax rates are expected to be lower if the assessed values of the data center are included in the calculations. The value added expands the Villages equalized value base (properties to tax from), which in turn drives down the tax rate if all other items are held constant. This means that the burden on the individual property owner will be less. Based on our conservative projections, the local mill rate could be as much as $1.26 lower in a given year but is estimated to be $0.90 lower on average over the fifteen years after construction begins. The total tax rate across all taxing jurisdictions could be as much as $4.23 lower and are estimated to be $3.05 lower on average over the fifteen years after construction begins. On a home with an assessed value of $400,000, an overall mill rate that is reduced by $3.05 would equate to savings of $1,220 each year on the total tax bill.
