I don’t agree with you .

I read comments back so time ago made by Mark W, on this site, in turn I followed Mark W advise and installed a 175kw battery system with a 35kw solar array and got off the Ausgrid network provider, so i don’t pay them one cent or pay other solar grid tied payments to those on the network which are free loading (rorting the Network).

This year i have save $15,000 in power bills payments to Ausgrid, beside this i don’t have pay for poles and wire or a grid solar rorting payment system that cause electricity bill to sky-rocket out of control.

No demand on the grid means no coal base load co2 emission, so get of the grid like Mark W told us, get off the carbon loading grid tied solar power and go at it alone.

Why do we continue to use an out date network that continue to pollute the planet with carbon pollution.
By going off the grid we cut carbon emission, if we continue to depend on the grid there is no hope of saving the planet because of the tree that get cut down for power poles to deliver carbon base energy to home.

That’s interesting. I’ll have to be more careful in the future.

Thanks. You are undoubtedly right.

The article doesn’t say but I’m pretty sure the battery is 60kW/240kWh. So four times the standard Tesla battery pack.

Enough storage to let individual houses store their own solar for use in the late afternoon/evening peak demand hours would make a huge difference on the supply side by lowering demand.

And then the end-user battery could store cheaper off-peak power to offset the early morning peak.

On grids where there is daytime solar and nighttime wind this can really cut into the need to access more supply during the early/late peaks.

Yeah, that would be enough for 1 off grid house…and they would have to practice some conservation measures. The company I work for installs battery systems of this size regularly. I guess the interesting and novel thing about this is that it will be used by the utility rather than the homeowners. Put one of these in every neighborhood and the peak shaving becomes very powerful.

The size is a “small fridge”. I think that puts it in the 60kwh range. That being said, I don’t think it would help much on the supply side…

I’m not sure if the author meant to say 60 kWh battery – because in that case you are correct. But a 60 kW battery is different, kW measure POWER, what can be produced instantaneously, while kWh measures ENERGY, what can be released over time. Clarification on this battery, like the Ahrs and voltage would go a long way. If the author did mean 60 kWh, but used kW instead, that would be an egregious mistake for an author for an energy-centric site such as this to make.

Isn’t one 60kW battery for the suburb of Newington rather small. I’d think that might be more appropriate for a household. Tesla uses batteries of this size in their smallest cars but most people buy the 85kW version. (Tesla did away with their 40kW version because practically nobody bought that.)

Are you sure it is one 60kW battery for an entire suburb?
