Horn Butte Wind Project
Gilliam County, Oregon


    Invenergy (as Willow Creek Energy LLC) submitted an interconnection request to BPA for up to 150 megawatts (MW) of power generated from the proposed Willow Creek Winds Project located in Gilliam and Morrow Counties, Oregon. BPA's has already agreed to interconnect up to 72 MW from the wind project to BPA's Tower-Alkali 115-kV transmission line in Gilliam County, and that portion of the project is currently operating. Invenergy (as Horn Butte Wind Energy LLC) is currently proposing to construct an additional 78 MW of wind power under the existing interconnection request. Construction of the Horn Butte Wind Farm is scheduled for 2011 and will consist of 52 GE 1.5 SLE wind turbines.

    BPA has already constructed the proposed interconnection site as part of the Willow Creek phase of the project. No new infrastructure would be needed to interconnect the remaining 78 MW, however some metering equipment would be placed within several of BPA's existing substations and within the wind farm substation.


    BPA will prepare a Record of Decision tiered off of it Business Plan EIS. If BPA decides to interconnect the project, interconnection of the wind farm would take place in 2011.


    A public scoping meeting was held on October 18, 2005, from 6 to 8 p.m. at Arlington High School, 1200 Main Street, Arlington, Oregon. Gilliam and Morrow Counties have held several public meetings as part of their Conditional Use Permit processes.


    The public comment period is now closed. BPA accepted public comments about interconnection of the remaining 78 MW through July 14, 2009.
