Fort McDowell Yavapai:
Harnessing solar power for energy independence and utilities savings

The Fort McDowell Yavapai Nation is located east of Phoenix in central Arizona. Not surprisingly, the large deserts of Arizona, including those in the Phoenix area, "offer some of the highest solar power potential in the country" according to the U.S. Energy Information Administration (see Figure 1; US EIA, 2009). In addition to the greenhouse gas reductions associated with renewable energy, the Fort McDowell Yavapai Tribe long ago realized the tremendous financial incentives posed by solar power. As Dan Catlin, Air Quality Specialist for the tribe explains, "Arizona should be on the forefront of solar energy. A lot has happened economically [in the energy sector] and as rates go up, the value of solar goes up."

Solar Photovoltaic Demonstration System
Project Implementation and Progress


In the interest of educating community members on the benefits of renewable energy, the tribe decided to install a solar demonstration project. The planning for this project began in early 2009 and a little over a year later, in March 2010, installation of the 12-kilowatt (kW) demonstration project was complete.

The system was initially expected to provide 15-20 percent of the energy for tribal headquarters building 2 (HQ2). As of mid-2010 however, the installation has been providing about 23 megawatt hours of energy annually, which is over 22% of the electricity used by HQ2. In order to fund the HQ2 solar demonstration project, which cost approximately $54,000, the tribe received approval to use funds from a section 103 Clean Air Act grant combined with about $27,000 worth of rebates from Salt River Project (SRP), one of Arizona’s largest utilities. In order to contract with the most qualified and affordable solar installer, a number of solar contractors were interviewed. Following the interview process and bid requests in the summer of 2009, the tribe awarded the project to a company by the name of S3 Energy, a Phoenix-based company.

Air Quality Monitoring Station Solar System
Project Implementation and Progress


In addition to the demonstration project on HQ2, the tribe also operates a small, 1.5 kW solar tracking system on the air quality monitoring station (see photo below). The six 250-watt panels track solar radiation throughout the day and currently produce about 50% of the monitoring station’s energy.

Moving forward, the tribe plans to install a second PV tracking system for the monitoring station after which they expect energy from the sun to produce as much electrical energy as the monitoring station uses.

Future Projects

Given the success of the solar demonstration project, the tribe is investigating options for other, larger renewable energy installations. Currently, work is being completed on a feasibility study for a 1-megawatt (MW) project. The solar PV system would supply energy to the tribe’s minimart gas station, an RV park, and a wastewater treatment plant. Catlin explains that there are far reaching implications for these renewable energy projects. For instance, by using a purchase power agreement (PPA), the tribe could finance the project, lower utility expenses, and simultaneously reduce tribal reliance on fossil fuel-generated electricity.

About the Fort McDowell Yavapai
Fort McDowell Yavapai Nation (FMYN) is situated along the Verde River within the Fountain Hills Sub-basin. This forty square mile community is located in the northeast portion of Maricopa County and is on the far northeastern edge of the Phoenix Metropolitan Area. The FMYN lands contain a number of enterprise activities, such as sand and gravel facilities, a golf course/resort/convention center, a casino, a gas station, a recreational vehicle park, a farm, and an outdoor recreation facility (Arizona Adventures).
