Potential Future Loads

I am doing an electrical infrastructure project for a 63 unit apartment building. The building is 208V 3-phase. We are going to transfer the circuits from the old service to the new service. I am proposing new meter banks and switchboards.

So far I'm designing a oneline diagram showing all the loads on the switchboards. One switchboard will be for the meter banks and the other switchboard will be for public lighting and power in common areas.

I want to provide spare switches to the public lighting and power switchboard. Can you guys give me ideas on what future loads the building could potentially have? Technology is constantly changing and buildings may potentially come off gas so maybe electric boilers is one thing that they potentially might have. Maybe cogeneration could be a potential circuit in the future. This building does not have a parking garage so I don't think EV charging stations are a potential load in the future.
 
With New York looking to ban natural gas you are really opening "Pandora's Box".... Having to change to electric boilers would likely be a monumental increase.

New York has so many unrealistic expectations... I feel like I should intentionally oversize their service because of this stupid New York law about no gas.

Nothing unrealistic or stupid about moving away from on-site natural gas for space heating. In the long run, beats the alternative.

Upstate the current infrastructure would not be able to handle this rapid conversion to full electric. The poco engineers near me have been unwilling to consider on new installations oversizing for future use.
 
I wouldn't worry about the possibility of that the building converting to all electric in the future. There is nothing that you can add in that switchboard that would accommodate an all electric 63 unit building. Besides no one is going to just change the entire gas infrastructure anytime soon. Just add some extra capacity for a potential future load and call it a day.
