Hardin Wind LLC, approved earlier this year by the Ohio Power Siting Board for a 300-MW wind project, applied Sept. 11 at the board for some changes in that prior approval.
Hardin Wind is a wholly-owned subsidiary of EverPower Wind Holdings. It received from the board a certificate to construct a wind facility (the Scioto Ridge Wind Farm) consisting of 172 turbines, along with access roads, electrical interconnect, construction staging areas, operations and maintenance facilities, and a collection substation. The project is to be located in Lynn, McDonald, Roundhead, and Taylor Creek townships (in Hardin County) and Richland and Rushcreek townships (Logan County).
The board approved the project on March 17. The company is now proposing minor changes to the approved facility design, including five minor turbine shifts, relocating a meteorological tower, minor changes to the access road and collection line system designs, and relocating the collector substation, which in turn will shorten the certificated transmission line. In addition, two new turbine models are proposed for consideration.
Final project designs are expected to be done in the third quarter of 2015. Construction is anticipated to begin in the fourth quarter of 2015 and run through the middle of 2016. The facility is anticipated to be placed in service at the end of 2016 after operational testing is complete.
“Due to market factors such as availability and cost, a specific turbine model has not yet been selected for the Facility,” said the company. “A number of turbine models that were determined to be suitable for this site were described in the original Application. Two additional turbine models are under consideration in this Amendment: the Suzlon S111 (2.1 megawatts [‘MW’]) and the GE 103 (1.7 MW). Both have shorter rotor diameters and are less in total height than the maximum rotor diameter and maximum total height of the currently certificated turbines.”
The actual number of turbines constructed will depend on the capacity of the turbine model selected, in order to reach a total capacity of 300 MW. If the 1.7 MW GE103 is selected, it is expected that up to 172 turbines will be constructed. If the 2.1 MW Suzlon S111 is selected, 142 turbines will be constructed.
“As indicated in the original Application, preliminary analysis indicates that the turbines will have capacity factors of 30-38%,” the company said. “Accounting for the total generating capacity of 300 MW, anticipated operating times, and turbine capacity factors, the Facility will generate approximately 788,400 to 998,640 megawatt hours (‘MWh’) of electricity each year. It is expected that the Applicant will develop, construct, own, and operate the Facility.”
