So much for getting cheaper.
It looks as though either Tesla is doing a "bait and switch" or they (he?) had no idea of the real cost of production.

That confirms my post a few days back and the crickets chirping in response when I asked why prices were still going up when the batteries and solar are supposed to be 70% cheaper now than 5 years ago...

A tiny country town has just received a 274-kilowatt-hour battery with help from government grants.

"It's taken a lot of time, a lot of organisation, a lot of planning. It had to be shipped here from China and it cost a lot of money at about $200,000."

ALL the farms in the area now have their own stand alone supply. Western Power install it and maintain it, including fuel for the backup generator. In fact, the customer is not permitted to touch it.

Where he has retired to on a 100 acre block he his going to install a similar system at a much lower cost than Western Power are quoting. The ironic part being that there is a bloody great 66Kv HT powerline passing through his block! There is also single phase powerlines right outside his gate.

And in 10 years who’s going to pay to replace them?

I met some of the people up there driving this a few years ago.

I have no doubt when the time comes to replace the battery they'll have a decent yack about it.

cheers, DL

Maybe mains power is the same.

When I enquired I was informed because it goes across the property I’ll have to pay service (connection) charges even if I don’t use it as the connection is there.

Having said that, that’s how costs are shared, if people just disconnected the remaining would need to pick up the difference and prices for them would continue to spiral out of control.

For me it is more a matter of knowing how long the battery is going to last. The cost has to be amortised over a time period, which at this stage is unknown. Just as with aircraft components, such as a turbine engine that can cost $50,000 to replace, the replacement cost is added into the hourly rate, because the time life is a known factor. The big difference here of course is that neither the time or replacement cost is known today. So the Kw unit charge has to take that into account, and as it stands, probably a best guess!
