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.

I'm fairly pro-nuclear but the EIA (Energy Information Administration) publishes a "Levelized Costs of New Generation" report every year that compiles the total cost of installing new generation, taking into account the fuel, build up, maintenance, interest, and inflationary costs, and nuclear ends up costing more $$$ than other renewable alternatives.

It's no conspiracy why nuclear never gets traction these days -- maybe it was cost-effective 10-30 years ago but renewable technology has gotten relatively cheap. (Shutting down active nuclear reactors earlier than needed is a whole different issue though.)

Here's the report for 2023: https://www.eia.gov/outlooks/aeo/electricity_generation/pdf/...

There is no report for 2024 because they are building a new model to take into account even newer technologies: https://www.eia.gov/pressroom/releases/press537.php
