I suggest you consult with a professional electrician in your area. Since you posted in the Electrical Engineering section, I assume you mean maximum electrical power demand. This figure is not dependent on area alone.
You can try adding more details and we'll try our best but your post does not provide enough information for us to give you a good answer.
