Depends on the wire coming into the building and the transformer on the pole. A decent electrician can tell. The electric company may have to upgrade the cable. Worse case they may have to upgrade the transformer on the pole. Usually they will do it for free but not always
If they do not have to, an electrician can just replace the panel with a new 200 amp or possibly just add another 100 amp box to the one you have now.
This is not a DIY deal either, . Hire a licensed electrician.
