Data centers notoriously do not bring much in the way of either jobs or tax base.
Meta's planned gigawatt-scale DC in Louisiana is projected to create ~500 jobs. If energy prices for the state increase by only 20%, that does not feel like something the people of the region would obviously want to do if given the choice.
I don't understand why the energy rates for residents should go up at all? Why isn't the data center paying for it? Even my personal bill gets more expensive per kwh the more I use, shouldn't a data center using exponentially more power just pay a higher per kwh rate, honestly to the point that they are making it cheaper for normal customers??
Georgia, where data center construction has been booming, has seen rate increases significantly higher than this. IIRC there have been 6 rate increases in the last 2 years, with a 24% increase in 2024 alone.
I don't believe any of this was part of the forecast of 10 years ago, so I would not trust a long-term forecast issued now.
