Ohio Rev. Code Ann. § 4909.16

When the public utilities commission deems it necessary to prevent injury to the business or interests of the public or of any public utility of this state in case of any emergency to be judged by the commission, it may temporarily alter, amend, or, with the consent of the public utility concerned, suspend any existing rates, schedules, or order relating to or affecting any public utility or part of any public utility in this state. Rates so made by the commission shall apply to one or more of the public utilities in this state, or to any portion thereof, as is directed by the commission, and shall take effect at such time and remain in force for such length of time as the commission prescribes.
