From the US Department of Energy Cast Study on wind development on the Rosebud Reservation:
"Since the late 1990s, the tribe has been actively pursuing wind development on the Rosebud Reservation. In March 2003, the Rosebud Sioux Tribe commissioned a single 750 kW NEGMicon Vestas wind turbine, which has come to be known as the Little Soldier (Akicita Cikala) turbine, in respect to the vision of Alex "Little Soldier" Lunderman and his contribution to this effort. This turbine was the result of a U.S. Department of Energy (DOE) grant awarded in late 1999, along with a matching U.S. Department of Agriculture Rural Utilities Service Loan. With the assistance of a developer and the Intertribal Council on Utility Policy (ICOUP), the RST applied for and received a DOE grant to develop a 30 MW wind farm. This resulted in the development of the Owl Feather War Bonnet Wind Farm. After five years, this wind farm's development is almost complete, with the exception of a signed power purchase agreement (PPA) and the resulting interconnection agreement. This signed agreement will enable the completion of the wind farm. The RST shall act as a passive landowner, reaping a percentage of gross receipts based on Grant of Use and Lease Agreement agreed upon by action of the RST Tribal Council and the Bureau of Indian Affairs."
2010 Project Update
"The Rosebud Sioux Tribe (RST) and Citizens Wind will complete the required pre-construction activities necessary to secure funding for the proposed 190 MW North Antelope Highlands wind farm, including identification of power purchasers, National Environmental Policy Act (NEPA) permitting requirements, transmission and interconnection studies, and subsequent interconnection agreements required to deliver energy to a specific set of potential purchasers. This project will result in delivery of all required environmental and cultural studies, permits and contracts sufficient to secure project financing."
