How much power does their microreactors generate?
Electrical output isn't listed, my wild guess would be about a quarter of that figure.
The page does indeed say that.
At the same time that seems like very little, it's in the range of a single large wind turbine (e.g. https://www.vestas.com/en/products/offshore/V236-15MW). I'm not convinced this will be anything but a niche application for defence or other remote outposts which for some reason cannot rely on solar+wind+storage.
Large companies with huge campuses could also use it for electricity + heating. Industry could also use the heat for chemical processes.
There are also places with small grids, where a bigger reactor can't be easily integrated, like islands or remote villages. I think Canada wants to use their BWRX-300 SMR for remote grids.
