United States General Services Administration (GSA) has signed a Power Purchase Agreement (PPA) with MG2 Tribal Energy for 140MW of wind power from the Walnut Ridge Wind Farm located in western Illinois, US.
The PPA deal is a first for MG2 Tribal Energy, which represents a partnership between the federally recognised tribal nation in southern California, Mesa Grande Band of Mission Indians and US based renewable energy firm Geronimo Energy.
The wind power facility, spread across an area of around 14,500 acres, is under development and is expected to have a total generation capacity of 225MW.
The PPA deal purchased by the federal body is likely to produce around 500GWh of clean energy in a year. It can thus eliminate around 499,973 metric tonnes of annual carbon dioxide equivalent emissions.
GSA administrator Dan Tangherlini said: "As part of GSA's commitment to greening the federal government, we are working to ensure that we don't just use energy but create it as well.
"This project will add to the power grid in a sustainable way and ensure that we become less dependent on fossil fuels. We are proud of our progress toward meeting the federal government's renewable energy goals, and look forward to taking advantage of future opportunities that will help us with this effort."
Mesa Grande chairman Mark Romero said: "The Mesa Grande Band is excited about our partnership with both Geronimo Energy and the GSA.
"With very limited opportunities to generate revenue on the reservation due to our remote location, the Mesa Grande Band has sought out multiple economic development strategies, including our partnership with Geronimo.
"This contract represents an important step forward in the history of the Mesa Grande Band because it is entirely consistent with our historic concern for Mother Earth and the continued availability of clean water, land and air for future generations. Few other economic development opportunities enable us to remain so true to our cultural and spiritual values."
Geronimo Energy President Blake Nixon said: "Geronimo is proud to develop economically viable renewable energy projects for customers, now including the federal government via this contract with the GSA.
"Our partnership in MG2 has been a mutually beneficial venture from the beginning, and by securing this PPA with the GSA, our partnership with the Mesa Grande has an exciting future."
