Ohio Rev. Code § 4928.07
To the maximum extent practicable on or after the starting date of competitive retail electric service, an electric utility, electric services company, electric cooperative, or governmental aggregator subject to certification under section 4928.08 of the Revised Code shall separately price competitive retail electric services, and the prices shall be itemized on the bill of a customer or otherwise disclosed to the customer. Although a competitive retail electric service shall be supplied to any consumer on such a basis, such an electric utility, electric services company, electric cooperative, or governmental aggregator may repackage the service on or after the starting date and offer it on a bundled basis with other retail electric services to meet consumer preferences. Such repackaging by an electric utility shall be subject to sections 4905.33 to 4905.35 of the Revised Code. Repackaging by such an electric services company, electric cooperative, or governmental aggregator shall be subject to the limitation that no such entity, as to a competitive retail electric service for which the company, cooperative, or aggregator is subject to certification, shall furnish free service or service for less than actual cost for the purpose of destroying competition.
