My home’s semi-peak rate is $0.37/kWh. I don’t know the peak rate since I have solar and always generate more than consumed, thus rate not showing on my bill.
My closest Supercharger (San Diego - Fashion Vally) charges just $0.31/kWh at 12pm noon. No wonder it’s always full during waking hours.
Tesla should study local residential rate to make sure to charge just a bit more, so that nearby owners don’t clog up the charging stalls just to achieve saving, leaving travelers and shoppers frustrated with long wait time.
Bottom line; Superchargers are not meant for local residents looking to save a few bucks.
