Yes - I live in the Bay Area and installed a 2nd meter in December (E-9B for car; E-1 for the house), plus new solar to bring us down to zero kWh. No bills received for six months, then they all came at once in late May. E-9B is good for at least a couple of years before to potential change to proposed new rate card for the EV program (which is still pending with the public utilities commission). Regardless of what happens with the rate plan, you can still have a 2nd meter. I think it's worth it, as E-9B night rates are very low.
From a project perspective I had to apply for 2nd meter to PG&E, get a new drop to the house, add the meter as well as a 2nd panel for the car - and then run wiring to the HWPC and my 2nd 50A backup circuit (which I had installed first since I took delivery of the Tesla in December, but was still waiting for the HWPC at that point).
