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.
No thanks. Instead lets fix our inability to build a thing in this country by reducing NIMBY regulation so things like power generation can be built where it makes sense, and we are allowed to do things like build long distance transmission lines again. Also start funding these societal-level projects like our grandparents and great grandparents did to invest in our futures.
No datacenter operator wants to deploy their own power plants. It's due to the inability for anyone to get anything done that is not directly under their control. You would be waiting decades for projects to happen otherwise, like many have. Utilities have abdicated their responsibility to build for the future, and regulators have let them. Just like anything infrastructure related in the country. You are now seeing the direct impacts of this, and they will continue to increase regardless of if the cause is AI datacenters or whatever other popular thing we want to argue about next.
