One idea is that the reactor is small and mass produced, not the power plant! So at a site similar to one where you have 2-4-6 big reactors now you would put 5-10-15 SMRs, with a similar large scale infrastructure (HV grid, transformers, security, water treatment, maybe cooling towers, etc.), but you can get going sooner as the reactors are standardized, with type-permits ready, which helps in the design and paperwork of the complete site, and the site might be able get going sooner at lower capacity, starting to generate revenue earlier.
