Adding a meter main to a service entrance section....

Adding a meter main to a service entrance section....

(OP)
OK, I could use some suggestions for this small commercial building design project!
This is a link to a picture of the switchgear.....

There are parallel 600A feeders running underground from the power company transformer rising up into the middle section, and there is a main disconnect at the top of that section. The two sections on either side are 100/2 metered house feeds (one feed the entire building complex, the other feeds the house for this particular building).

So, now a tenant is moving in, and I am not sure how to provide a metered service from a set-up like this. Initially, I had nothing but a single line diagram to work from, and I assumed that a meter/main module could be installed in the service entrance section. I'm not sure now if that would be possible.

The electrical contractor has offered two suggestions - to use a bus kit to extend to a brand new CT meter section with a main circuit breaker, which would be expensive.... or to tap off of the 600A bus and extend to a standard meter main - less expensive, but what about the unmetered tap?

Any other suggestions? I am not sure why the original design didn't account for a need for a tenant meter, but so be it. I'd like to be able to just throw a meter/main in the service entrance section, but I am not sure if that can happen. I could really use some insight into this!!!

Thanks guys.

RE: Adding a meter main to a service entrance section....

(OP)
PS - Could I replace the service entrance section (27") and one of the house sections (15"?) with a CT Meter section with a main (36"), and relocate the abandoned house loads and reconnect the second house section?  Would the meter/main section have provisions for service entrance?
