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.

Nuclear is a terrible investment in 2024. Price per delivered megawatt-hour is guaranteed to be much lower for a combination of solar+battery+wind.

-- Edit --

To clarify, "Nuclear is a terrible investment for private industry in 2024." However, I understand why nation states (and their equivalents) would want a diversity of power sources. There many be non-economic reasons why nations want to build nuclear over solar+battery+wind.

Nuclear may not be competitive for electricity, but it could be a viable option for district heating. If you ignore electricity generation completely, you could make small simple low-pressure reactors and hide them underground. There is a spin-off company from a national research institute in Finland that believes it can make 50 MW (thermal) reactors for €100 million, with some municipal utilities semi-committed to buying ~15 of them.
