alt Hacker NewsThe article says that Michael Turner, the vice chair of the county's government, doesn't believe they were trying to find tricks or deceive anyone. That makes it a lot harder to justify shutting them down. And potentially quite expensive, if they or their users can argue the county is liable for the costs.
You mention properly incentivizing the grid operator, but this is also not so simple. As Dominion describes in their FAQ (https://www.dominionenergy.com/virginia/large-business-servi...), providing power to a large datacenter is itself a substantial construction project, requiring its own permits and specialized components. It's not just a matter of paying enough to get some guys working overtime.

Talking about motivations would seem to be a smokescreen, a politician still trying to grease the wheels to allow the project to continue despite the harm to local residents. The point is that any engineer overseeing the deployment of turbines would have said "these things are loud" - it's an externality eminently foreseeable by the owner.
And yes, my point is that the theories of liability that would make the county liable for any of these costs need to be drastically curtailed. The responsibility for a datacenter owner trying to force their externalities onto existing land uses and failing should rest on the datacenter owner, not on the people whom they attempted to harm.
