Based on the headline I thought that this was an enormous capital commitment for an enormous generating capacity, but the deal is with a company called Kairos that is developing small modular reactors with 75 megawatts of electrical output each [1]. 7 reactors of this type, collectively, would supply 525 megawatts (less than half of a typical new commercial power reactor like the AP1000, HPR1000, EPR, or APR1400).

Kairos is in a pretty early stage. They started building a test reactor this summer, scheduled for completion by 2027:

EDIT: Statement from the official Google announcement linked by xnx below [2]:

Today, we’re building on these efforts by signing the world’s first corporate agreement to purchase nuclear energy from multiple small modular reactors (SMRs) to be developed by Kairos Power. The initial phase of work is intended to bring Kairos Power’s first SMR online quickly and safely by 2030, followed by additional reactor deployments through 2035. Overall, this deal will enable up to 500 MW of new 24/7 carbon-free power to U.S. electricity grids and help more communities benefit from clean and affordable nuclear power.

Yeah I’m not going to lie, that’s quite disappointing. Google funding several AP1000’s would be huge.

Google's entire thing only consumed on average 2.6x worth of AP1000 energy last year. Why does anyone think that the IT industry needs to pull all of the weight of electrifying the American economy by building 7 AP1000 power stations?

You raise a very good point. I need to do some research to understand your comment.

1) Google uses about 25 terawatt-hours per year. Source: https://www.statista.com/statistics/788540/energy-consumptio...

2) An AP100 nuclear reactor can produce up to 10 terawatt-hours per year. Source: https://canes.mit.edu/overnight-capital-cost-next-ap1000#:~:....

That is incredible to think just how much power that a single nuclear reactor can produce!
