BPA Interconnection of the Proposed Shepherds Flat Wind Farm
Gilliam & Morrow Counties, Oregon

Bonneville Power Administration (BPA) has been asked to interconnect up to 846 megawatts (MW) of electricity from the Shepherds Flat Wind Farm, a private energy facility, proposed in Gilliam and Morrow counties, Ore. The BPA interconnection facility would require constructing a new yard at an existing BPA substation in Gilliam County in 2008 and 2009. BPA does not propose to purchase any of the power produced by this wind project.

Caithness Shepherds Flat, LLC would develop the wind project on privately owned grazing and farming land near the town of Arlington. The wind project would be developed in phases, with the eventual installation of up to 303 3.0 MW turbines. Two transmission lines would be constructed between the wind project and the BPA interconnection site.

The wind project must go through Oregon Energy Facilities Siting Council (EFSC) review in order to obtain a site certification. The developer, through the EFSC Site Certificate Application process, has conducted environmental studies for the proposed wind project and associated facilities and is in the final stages of Siting Council review.

BPA interconnection project has completed the environmental review stage and is proceeding to construction. BPA issued a Record of Decision (ROD) under the National Environmental Policy Act (NEPA) on July 18, 2008. BPA believes the decision to interconnect the wind project is consistent with BPA's Business Plan ROD, August 1995 and Business Plan Environmental Impact Statement (EIS), June 1995.
