Ohio Revised Code Title XLIX. Public Utilities § 4928.47

(A) An electric distribution utility may, on a nondiscriminatory basis and subject to approval by the public utilities commission, enter into an agreement having a term of three years or more with a mercantile customer or group of mercantile customers for the purpose of constructing a customer sited renewable energy resource in this state that will provide the mercantile customer or group with a material portion of the customer's or group's electricity requirements.

(B) Any direct or indirect costs, including costs for infrastructure development or generation, associated with the in-state customer-sited renewable energy resource shall be paid for solely by the utility and the mercantile customer or group of mercantile customers. At no point shall the commission authorize the utility to collect, nor shall the utility ever collect, any of those costs from any customer other than the mercantile customer or group of mercantile customers.
