Large scale clean power storage soon a reality?

Yeah, this guy was on Radio National this morning, saying that Tesla batteries are capable of being deployed on such a scale that they could have prevented SA losing power during that recent heatwave.

Quite remarkable, if true, and possible at acceptable cost:

Tesla's confidence of being able to plug gaps in grid power has been buoyed by its successful completion of a similar assignment in southern California last year, when it built an 80MW battery farm in 90 days after a gas peaker near Los Angeles leaked tonnes of methane and had to be mothballed.

Tesla was one of three battery companies to step forward when the California power system operator called for emergency storage and it is one of a large number of battery companies vying for the 1.6 million solar rooftop homes and businesses in Australia.
"We could install everything and get it up and running within 100 days," Mr Rive said at the launch of Tesla's Powerwall 2 battery in a converted substation at Newport, near Melbourne.

"We had a similar challenge in southern California ... We got 80MW up in 90 days. That's unheard of. You just don't get power plants running up and down that fast."
