So there's a 200 amp relay in the meters now? I can't find anything.

My home power installation includes an automatic transfer switch for an outboard generator.  The electric company replaced the meter assembly with a new one that sticks out an additional 6 inches and added another metal box for control circuitry and the plug for the generator to connect to.  The 200 amp transfer relay is inside the new meter assembly.  It is noticeably bigger than the old one and is hard to miss.

If they replaced the meter assembly with one to support remote monitoring, it is conceivable they could have  included a 200 Amp relay in there.  The relay wouldn’t need to be physically larger than your main power breaker, but I would expect to see the whole meter assembly be a bit bigger than your old one.

That's what I was asking about. I can't find anything that says they do that, and no one has posted any links.

The new meters do indeed have service relays in them.  Keep in mind nec never intended 200 amps continuous ratings anyway.  The power company will still charge you a reconnect fee if you don't pay your bill in a timely fashion.

I assume this capability is standard in smart meters. PECO for example also mentions it. As does Dominion: https://www.dominionenergy.com/company/electric-projects/smart-meters

WILL SMART METERS BE USED TO REMOTELY TURN OFF MY SERVICE?

Smart meters enable BGE to remotely turn service on
and off at a customer’s home. This feature will be used
when a customer moves out of their current home and
start service elsewhere. BGE’s policies for situations
involving disconnection are the same as they were prior
to the installation of smart meters. The remote connect
feature also enables BGE to put customers back into
service more quickly.
