Many large PG&E cities do not allow the 2nd meter.
SCE rules ... unknown, sorry.
SCE people on the phone have told me they are not charging anything for the second meter, either at installation or monthly. I believe they used to charge $ 3 or so per month but not now, at least for the EV program.
I agree for folks like garygid, with a crowded main service panel, a completely separate free second meter panel with a single 40-amp breaker would be the way to go. In my case, I want to get a new panel to support remodeling, and the "two-meter adapter" might be simpler for me.
A completely separate meter means that SCE must approve the details of how they are both connected to the lead-in, because wiring before the meters is "theirs." As I understand things, I pay my electrician to install everything, and SCE just comes out to connect it, but I can't get any detailed guidance for the electrician to follow.
I will ask my local city inspector. The SCE service planner, when he visited, told me that all the second meter installations that he had seen (for other purposes, not EV) were assigned a separate address (-A, -B etc). If that satisfies both the city and SCE, that should work.
