The Ohio Power Siting Board on Nov. 12 granted an application filed by Hardin Wind LLC to add two new turbine models to the list of turbine models, change the location of various associated facilities, and add new associated facilities to its wind farm project in Hardin and Logan counties, Ohio.
In March 2014, the board granted the applications filed by Hardin Wind for certificates to construct a wind-powered egeneration facility, a substation, and a transmission line in Hardin and Logan counties.
In September 2014, as revised in December 2014, Hardin filed this application pertaining to the certificates issued in the so-called Hardin I Case. Hardin proposed to change the location of one meteorological (met) tower, five access roads, six collection lines, and the collector substation; add two new access roads and six new collection lines. In addition, Hardin proposed to add two new turbine models, the Suzlon S111 and the General Electric 103, to the list of possible models to be used.
The staff of the Ohio Power Sting Board in a report filed Sept. 4 recommended that the board approve the changes. In March 2014, the board authorized Hardin Wind to construct a wind-powered facility consisting of up to 172 turbine sites with a combined generation capacity of 300 MW. The project is called the Scioto Ridge Wind Farm.
The new turbine models approved are the Suzlon S111 (2.1 MW) and the General Electric 103 (1.7 MW). The Suzlon turbine would have a rotor diameter of 111 meters, a hub height of 90 meters, and an overall tip-height of 479 feet. The GE turbine would have a rotor diameter of 103 meters, a hub height of 96 meters, and an overall tip-height of 486 feet.
The overall project nameplate capacity of 300 MW approved in the original case does not change. Therefore, the actual number of turbines constructed would depend on the capacity of the turbine model selected in order to reach the total generating capacity of 300 MW.
