Yeah, that's definitely bullshit, esp considering residential power in the PNW is $0.07/kWh.

- DannyBee 9y agoResidential power is often cheaper than commercial (at least, small scale) in practice. One reason is that commercial folks pay surcharges for power factor. For example, in San Jose, CA, the average residential is ~$0.156/kwh Commercial is $0.1408/kwh [1]. If you operate at a 90% power factor, and are surcharged the other 10%, ...

I could believe that to be the all-in cost for a supercharger or something weird like that. Because they should be paying close to the industrial rate, if not lower.
- jimrandomh 9y agoNope. Electricity for residential use costs more than electricity for commercial use, which costs more than electricity for industrial use. A fast-charging truck stop is most similar to industrial use, since it involves a lot of power at a single location, and probably also can give the utility at least a few minutes warning before ramping up to full power.
