Northern Arizona University student helps tribe's economic development

When Jemez Pueblo leaders in northwestern New Mexico wanted to weigh the benefits of building a renewable energy project, they joined a national program that pairs tribes with Native American college student researchers. It was ideal timing for Northern Arizona University (NAU) mechanical engineering graduate student Cherise John, who used the project for her thesis, which she will present this semester. “The pueblo is looking to generate some sort of income, so part of what we did was create an economic analysis for building a large-scale photovoltaic system,” explains John, who worked on the project with students from New Mexico’s Southwestern Indian Polytechnic Institute.

Building a 40-megawatt photovoltaic system and connecting it to the power grid could cost the pueblo $90 million. John and her colleagues determined that the Jemez Pueblo could provide energy for the reservation and turn a profit if tribal leaders negotiated a standard purchase price with the power company. The next phase of research is a transmission study to determine how much power the tribe could add to the grid. “Once we find out how much energy we can actually put on the grid, I can begin optimizing the design of the PV array system,” John says. “I think if we can do this for the tribe, it opens up a lot of doors for other tribes to help them in their economic development efforts.”

The research was sponsored by the American Indian Science and Engineering Society and the American Indian Higher Education Consortium and funded by the U.S. Department of Energy’s American Indian Research Education Initiative. In addition to John’s project, students at other institutions researched different real-life scenarios.

The project, managed by NAU’s Institute for Tribal Professionals (ITEP) Tribal Clean Energy Resource Center, is important to the university’s strategic mission, says Mehrdad Khatibi, director of ITEP. “Projects like this one give exposure to students who work on renewable energy technologies and learn what it means to work for a tribal community in the process.” Khatibi worked closely with Cherise John and her adviser, mechanical engineering professor Tom Acker. “It is important for students to work through some of the decisions tribes have to make when they are considering these renewable technologies,” Khatibi adds.

John’s upbringing in New Mexico influenced her career goals of optimizing energy production and reducing byproducts. “The reason I wanted to become an engineer is because I grew up between two mine sites and two power plants. I saw the pollution and I understood the economic side of it,” says John, whose parents worked at the power plant. John recently traveled to Arizona State University to present her findings to tribal leaders and U.S. Secretary of the Department of Energy Ernest Moniz.
