- 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."
