Yeah, I get demand charges and why the electricity companies charge them. This presents a prime opportunity for Tesla to use their Powerpacks to smooth demand. Considering the Superchargers are rarely full, or even half full, A single Powerpack per install or a couple for the larger 8 or 10 stall Superchargers would significantly mitigate the demand charge. Based on Powerpack's specs of 130kW continuous output and 232kWh storage, one Powerpack could potentially more than halve a 4 stall Supercharger's grid demand. Tesla has mentioned using energy storage to supplement their Superchargers in the past. Do we have any evidence they are doing this yet?
