I live in Maine. Commercial power is crazy expensive. I don't know why you would build an AI datacenter here in the first place. As an obsessive self-hoster, I've researched building one, and there is no universe in which it makes sense. New Hampshire and Massachusetts are so nearby latency-wise.
As has been repeatedly demonstrated[1], it is the presence of new, large consumers that drives down the cost of bulk power by amortizing the infrastructure investments.
Maine voters are, of course, notorious bozos in this field, having voted in a plebiscite in 2021 to cancel the link to Quebec Hydro, which was already substantially completed.
This is so ignorant it hurts. The same exact proposition was voted down in New Hampshire years earlier, because the transmission line goes straight through natural forests, to Massachusetts, and has little to do with the state other than chopping down a bunch of trees. Neither Maine nor New Hampshire have an extra $1 billion to waste on enhancing the grid mainly for the benefit of southern New England states.
Neither Maine nor New Hampshire voters are "bozos" for voting it down. The whole ordeal even prompted Maine voters to establish a new law to stop foreign investors from influencing local referendums because Hydro Quebec spent so much money trying to sway the vote.

I mean yes, that is how the Tragedy of the Commons works. Everyone individually makes the optimal decision for themselves but in effect you've basically hamstrung green sources of energy around the country by being very smart for your own state.

"...you've basically hamstrung green sources of energy"?
Well, after we stop growing corn to feed exclusively to cars and start using solar panels deployed on that land to harvest electricity for cars and houses and everything else that runs on electricity [0], if we're still short on power we can have the discussion you're itching to have.
[0] The immediately relevant discussion starts here <https://www.youtube.com/watch?v=KtQ9nt2ZeGM&t=1930s> and runs through to about 38:29, but the entire video is very, very well worth watching. If you intend to watch more of the video after ~38:29, I very strongly recommend that you start from the beginning.
Maybe Massachusetts should have offered Maine some incentive for running the power line through their territory. States make agreements like that all the time.
Do you have any links to support this? Because the commonality of all arguments _against_ has been that they make water and power crazy expensive for everyone that has to live close to the newly opened datacenters, while the DC operator enjoys subsidized land use tax, water and power.
Indeed, considering the much of the cost in the end consists of carrying costs, litigation, and year-of-expenditure overruns that were caused by the delay.
Even in inefficient data centers, cooling is a minority of the power expense. Chasing a few percent of better cooling efficiency at the expense of a few percent more expensive power is a net negative.
Cheap power is much more cost effective than the smaller efficiency bump you get from cold weather -- and you can also get both by locating in the midwest or northwest. Hyperscalers build here for these reasons.
Cooling is a very variable 30% cost. (IE: Iron Mountain's underground Datacenter with a flooded reservoir in the mine gets to brag about 5% of its cost being cooling, as the most extreme low end).
Up north comes with it's own issues for Datacenters. Winter low humidity (kills cable/wire insulation), chiller freeze protection can get pretty complex to set up properly (with failures causing complete destruction of some components that will need multi-ton cranes to replace), and multi-year construction projects are harder with real winters. Sure it's all perfectly manageable engineering wise, but why bother.
There's probably easier green energy credits down south, given the current viability of solar.
I don't know about this particular situation (NH and MA seem to have expensive power as well), but you can have significantly different costs on one side of the line or the other for regulatory reasons. State regulations can affect the cost of business significantly, and electricity is no exception.
I'm from Nevada. Very aware that California has more regulation (and hence more cost than us), but know little about the regional cost differences between Maine and Massachusetts.
They are very dependent on natural gas and they also heavy environmental protections/pollution regulation that makes it hard to build stuff like pipelines and, hence, makes electricity more expensive compared to states with less environmental protections.
Power is not the most expensive part of data center lifetime cost; especially these days when you're filling them with several billion dollars of nvidia chips. It's still an important consideration of course, but not the only one.
I don't know if that's really true. Given realistic life cycles of equipment (~10 years, not 3 as commonly believed) the operating power is going to be 75-80% of the TCO, or more.
In fairness your calculation looks at the most expensive element of the DC but ignores all of the associated parts required to utilize the H100: CPU, memory, cooling, etc. No to say that that flips the calculation (I don't have the answer), but it does leave a lot of power out.
Let's be generous and pretend the rest of the hardware is free but double the energy budget of the H100 to account for all of it along with cooling. You're still at only $1k/yr; $10k over 10 years, or 25% of the TCO (ignoring all other costs).
