The Ohio Power Siting Board
Before construction can begin on any major utility facility or economically significant wind farm within the state of Ohio, a certificate of environmental compatibility and public need must be obtained from the Ohio Power Siting Board. The Ohio Revised Code defines a major utility facility as:
- Electric generating plants with a capacity of 50 megawatts (MW) or more
- Electric transmission lines and associated facilities of 100 kilovolts (kV) or more
- Gas pipelines that are greater than 500 feet in length, more than nine inches in outside diameter, and designed for transporting gas at a maximum allowable operating pressure in excess of 125 pounds per square inch.
- Economically significant wind farms and associated facilities with a single interconnection to the electric grid and designed for, or capable of, operation at an aggregate capacity of 5 or more MW but less than 50 MW.
