$30 per month for unlimited night rate electricity

looking further though - can someone clarify what is the max current you could pull for charging?

i.e. the $30 seems to be for unlimited charging - not unlimited electricity at night. but for most people, the difference may be moot, i suspect?

the average energy consumption in the states appears to be ~900kWh per month - or about 30kWh per day. what's the average battery install for their customers? i.e. if you charged at night and tried to draw down 30kWh per day, you'd quickly run your batteries dry, i presume? maybe this is a way for tesla to drive consumers to a massive capital investment in their batteries.

that's my point - you're very invested in the technology, and have 50% more capacity to store what the average american household uses in a day. but you can bet your bottom dollar that the average american household doesn't have within an asses' roar of that.

let's say (plucking a figure out of the air) that the average in the states is 6kWh of storage. at the rates i can see per unit in the PDF i linked to, it'd cost about $1 to charge that. and if they're offering that $30 for charging only, that's already what they're paying to fully charge the battery every single night.

as i mentioned, this seems simply to be a way for tesla to get people to buy more batteries.

i think we're coming at this from different assumptions; i googled to see what was on offer and this was the first result.

it suggests that they are not offering night rates *all day* - it suggests that they're capping a price on charging at night, no matter how much electricity you use to charge?

"If charging at night is an option for you and you drive quite a bit, $30 per month is going to result in significant savings."

so my assumptions based on that were:

1 - the $30 only applies to consumption at night

2 - it applies to charging consumption only.

i.e. your consumption, as long as they meet those two parameters, can be unlimited.

well, that doesn't change my other point - who has the capacity to use 135kWh at night? you'd need a huge battery bank and/or several cars whose batteries you are fully draining on a daily basis. you do, but for the vast majority of americans, it might be worthless.

do tesla collect data on the usage of their batteries? in the states, i'd have kinda assumed they do - that they could potentially distinguish what is used for charging a battery vs what's being pulled into the home.

but that contradicts what you said in your previous post - "Nobody knows what you use your electricity for. That's private." so tesla know how much electricity you've used, to charge tesla batteries, which was my question.

again, i'll go back to my previous point - you're talking about a price per unit which is essentially hypothetical; only achievable if you're actually using 135kWh every day. the average in the states is 30 (and A/c would be a large part of that there)

you'd have to be doing a lot of driving to make up the difference, averaging 600km or 800km a day or thereabouts to use that in charging an electric car.

or leaving your power shower on 24/7 at greater than half power.

is powerwall not their house battery system? from the link i posted:

"Tesla Electric is actively and automatically buying and selling electricity for Tesla Powerwall owners – providing a buffer against peak prices.The company is essentially becoming an energy retailer.

Tesla Electric is currently only available to Powerwall owners in Texas"

in the context of texas, the average unit price is 12c, so $1 a day would usually buy you 8kWh. so it makes sense if someone is able to pull down and store more than 8kWh a night, and use it all the next day (using it is probably reasonably trivial given the average daily consumption is approx 30 units, but that's ignoring the costs of installing the equipment in the first place, which would change the calculation)
