2 services 1 building

I am bidding a service upgrade at a small commercial business that was built in the 1970’s. The service is currently a 240 volt 200 amp single phase that is coming off an overhead transformer to a meter socket. The original install has 2 sets of service conductors, 100 and 200 amps, coming out of the meter. Somehow they were able to stack the wires under the lugs. Out of the meter each set went to a disconnect mounted directly below the pole mounted meter. For some reason the disconnects were gutted and wires spliced straight through. There are 2 separate panels in the building but are located 200’ away from each other. So currently the utility is pulling the meter to shut down the building. The utility has noted that the energy consumption is in excess of the existing 200 amp meter socket demands and upgrade to a 320amp and an external disconnect. Finding equipment to correct this is a challenge. I found a pole mounted 320 amp meter socket with 2 individual disconnects, 1 -200 amp and 1 -100amp. Each breaker is in their own compartment for separation. The 2 services to 1 building is 1 of several issues here. I have been looking at 230.2 for clarification but this situation is kind of unique being it is an existing service. Any input would be appreciated.

If you are going to have a disconnect at the pole Art 225 would apply and the two feeder allowance will depend on your Code cycle
