Before you do anything else, I suggest reading section 366 of the Bankruptcy Code. Then do some legal research to find out whether, in your judicial district, a utility company has to obtain relief from the automatic stay in order to shut you off or whether, instead, they can just do it if you don't provide whatever they demand in the way of adequate assurance under 366(b). Only an Ohio bankruptcy lawyer is qualified to give you the answer to that question, and the result may well be different for different kinds of utility because it may depend on the state utility regulations.
