It works that way in California for households using PG&E, Southern California Edison, or San Diego Gas and Electric Company [1].

Same up here in Washington for service to a single family residence through a single meter for customers of PSE [2].

quite a few of the providers in Texas are exactly the opposite strangely.. they bill a surcharge for using less than some fixed KWh. i.e. I get charged $5 if i use less than ~500KWh in a month.
