Just another glitch evidencing a global conspiracy against the detail obsessed
A Tesla Powerwall2 retails for about $13k for 13kWh. No way the raw manufacturing costs are $65 for 77 of them.
$65/mwh works out to $0.065/kwh, so that makes sense. Effectively you can read this as "it costs $65/mwh to store and then consume electricity using these batteries"
But now it’s time to better understand why a Powerwall or other wall-mounted units are so much more expensive. I understand UL-listing costs, marketing, warranty, and other things are thrown in, but it’s $75/kwh versus $1000/kwh, a 13x difference.
If even at a $100/kwh price point all homeowners need to get 10-20kwh in batteries just to help peak shave the grid and save tons of money since batteries will be a fraction of the cost of grid power.
