Featured Aussi Powerwall, Musk pisses off climate deniers

Well yes, both used Tesla batteries, but the Powerwall installed in australia had standard samsung battery cells, not the model 3 improved panasonic cells made at the gigafactory. The construction of the modules also didn't have anything to do at the bottle neck in the gigafactory to make model 3 specific modules (model S/X modules are smaller and different). So no, other than management tasks, they have different people and parts, so no conflict.

Model S and X production at the Fremont assembly plant are being reduced this quarter to move resources to the model 3. Model 3 appears to be tesla's highest priority. The solar roof plant was also delayed because of model 3 manufacturing issues, as this might have taken management resources away.

 

no - modern grid interconnectivity is such that as demand Ebbs & flows, facilities can properly regulate. Perhaps what you miss is that Australia is coming out of the Stone Age - power wise, & trying to get rid of it coal burners. Watch the video.

It may help for folks understand better - that this is just a start - & not meant to be a cure. It doesn't make sense to complain that, "oh my God this is not enough!"
What should they rather .... do nothing? Give aussies a chance. The future is coming, & it's just around the corner. Some will say, "we are moving too fast! " while others - "we're moving too slow!" the rest will say, "chill..." or, "let's see you do better yourself"

The South Australian Tesla battery just helped mitigate a frequency issue happening due to a trip over 1000 km away.

Wow, if that one Tesla battery station did this, I wonder what several dozen of them could do, at a fraction of the cost of having to keep those other stations on standby mode.

 

The Tesla battery did not resolve the situation but it reduced the effect and responded quicker than anything else.

 

Traditional power grids need a 'spinning reserve' big enough to cover the largest single machine (generator), so that a single machine suddenly tripping out doesn't take down the whole grid. More reserves would cover larger system failures.

These battery systems certainly ought to fit into this reserve strategy, providing faster response while allowing greater time to spin up and warm up traditional machines. And with no smokestacks and other traditional siting constraints, they could be distributed more strategically and widely with lower environmental impact.

Though I'm not so sure about the 'fraction of the cost' claim. These plants will probably need to stand on their other merits.

 

Pumped water is not faster than batteries. Pumped water is cheaper than batteries if you have it at the right place ;-) Think of it this way, batteries are easy to locate anywhere you need them, and can react in seconds. Pumped storage if it is good in about a minute, but it often is not where you need it. Round trip pumped storage is around 80% efficient, and normally built to be run for 6 hours or more. Batteries typically in a grid application are specified to be able to give peak power for 5 minutes to 2 hours depending on the application. IIRC this tesla battery can provide it for about an hour.

The batteries didn't take much of the load (energy) but stabilized the grid. The spinning resource took 8 seconds from the alert. The battery 4 seconds, but it didn't get the alert, it just monitored the grid ;-) Idealy if you had a battery to cover the first 5 minutes of a problem, then pumped storage or fast ccgt natural gas, the battery could give the time to diagnose and start the other energy to protect the grid. Currently on the australian grid there is coal operating inefficiently to give grid stability.

I don't think the batteries are really good for energy, but are great for short term power. Australian coal power plants take a long time to start up, so unless you have a better back up, they need to be spinning, just in case. As bob mentioned pumped hydro, that is probably a great solution for australia. In the us batteries could be used until natural gas units can be fired up, which is much faster than coal.

Looks the same as post 23
Great minds think alike? Or fools seldom differ?

 

A.D.D. in full swing ... I humbly apologize for skimming.

I felt fortunate to see that story early. We all miss things on threads.
I enjoy your Tesla insights even though I will never be able to own one.
