Ohio may provide a sales and use tax exemption for certain tangible personal property used in energy conversion, solid waste energy conversion, or thermal efficiency improvement facilities designed, constructed, or installed after December 31, 1974.

Qualifying energy conversion facilities are those that are used for the primary purpose of converting natural gas or fuel oil to an alternate fuel or power source excluding propane, butane, naphtha, fuel oil, or natural gas. Solid waste conversion facilities include those that convert solid or semi-solid waste from industrial operations including public utilities, commercial distribution, research, agricultural, and community operations, and including garbage, street dirt, and debris. Thermal efficiency improvement is defined as "the recovery and use of waste heat or waste steam produced incidental to electric power generation, industrial process heat generation, lighting refrigeration, or space heating."

Facilities must apply for an Exempt Facilities Certificate from the Department of Taxation, which must also be approved by the Development Services Agency. Upon receipt of certification from the tax commissioner, such property is exempt from Ohio's sales and use tax. The application for Energy and Solid Waste Energy Conversion and Thermal Efficiency Improvement Facility is found at on the Ohio Department of Taxation web site (form number ECF).
