More Efficient Design with Load Shed?

[Designer69]

Please see attached pic.

Design option 1 requires 3 panels and no load shedding. Option 2 requires only 2 panels but load shedding of 60 loads.

In this particular application, which is the better design?

I guess if it is really feasible/possible to shed 60 loads, then option 2 could make sense but you'd still need a main service disc. sw. vs. a panelboard so I'm not sure there's really any cost savings in option 2.


Thank You

Loads?

Demand structure rate?

Overall rate structure? (poco pricing)

option 1 is simpler and uses a much lower rated ATS.

panelboards are relatively cheap anyway.

How are you going to load shed the loads in Option 2 in panelboards? Shunt trip? Then who will have to go reset those breakers.

Option 1 seems much simpler to accomplish and operate.

Ok thank you. I wasn't sure what current load shedding technology is capable of. Thought maybe it's possible nowadays to just program and shed as you please. Guess not haha

I did design this job with option 1, just wanted to check here to make sure I didn't provide a less efficient design.

Thanks
