Solar farming

[nzoomed]

I guess I'm thinking more of load balancing.
Not sure if it's more economic or not, but larger batteries further away from homes may not be as practical as smaller units scattered around suburbs.
As the price comes down, it might not be so much of a barrier.
Prismatic LiFePO4 cells only cost about 50 dollars USD overseas, but they retail here for 6 times the price, even then that's pretty cheap but shows the high margins retailers are charging.

Things are progressing fast in this sector. Contact has today announced that it will be installing a 100MW/200MWh Tesla grid scale battery at Glenbrook with another planned at Stratford.

My comment on domestic uptake of storage units (static batteries, EVs/V2G) was in regard to not only distribution of storage but more so in the potential cumulative storage capacity of thousands of home batteries and EVs. Considering we have ~80,000 BEVs and 10s of thousands of home batteries that is potentially >5GWh of connected storage potential spread across the country, so perhaps 1 GWh assuming those EVs and batteries offered only 20% of their capacity serving duty as a VPP (virtual power plant). Not an insignificant buffer capacity for the grid.

Thats awesome news, those Tesla batteries have proven themselves in Australia, looks like Alice springs is now running almost entirely off solar now too with their recent battery thats installed.
They must be tolerating the heat well over there, I guess they have a decent active cooling system installed.

Oh yes good point, V2G has some good potential. The only issues I see is how and when the vehicles are used and charged. If they are out and about at work during the day and only bought home and plugged in at the evening after the sun has gone down then there might not be much benefit.
They can still act as a grid buffer though if left plugged in and you could charge it with electricity during off peak times and use it during peak hours to save costs if nothing else.
