- cheaper - much less upfront capex, lower operating costs

- removes nasty geopolitical dependencies on eg gulf state oil and gas; costs are more predictable

- easier to plan and build because the base units are much smaller

Variability remains a valid objection, to which the main answer today is "batteries. Lots of batteries. And other cheaper longer duration storage, like sand heat storage, vanadium flow, and good old pumped hydro."
