Solar Photovoltaics with Battery Storage Cheaper than Conventional Power Plants (cleantechnica.com)

I'll note that aggregate system cost still benefits significantly from including wind and other non-solar sources of energy; having a mix of different intermittent sources (and some firm generation such as geothermal) means less storage is needed.

How does solar + pumped hydro compare? I thought I read somewhere the cost of pumped hydro per unit of storage was crazy cheap (assuming suitable enough sites are available). I think that kind of system probably makes a whole lot of sense too for places where the geography allows.

Pumped hydro is great but limited by site availability

Yep, it's great that batteries have gotten cheaper as they can be used basically anywhere.

I'm selfishly thinking of Australia in particular where we have almost 70 TWh of potential storage.
