For decades the Navajo Nation powered the American Southwest. The coal under Black Mesa ran the Navajo Generating Station, 2.25 gigawatts that lit Phoenix, Las Vegas and Los Angeles, while thousands of Navajo families lived under the transmission lines with no electricity of their own. Brett Isaac grew up next to the Kayenta mine, in a family that worked in coal. As a kid he rode with his uncles to load trucks with coal for the winter, came home covered in black dust, and started wondering who was going to clean it up. In his twenties he started putting solar panels on off-grid homes in his father's community of Shonto. About 200 homes later he co-founded Navajo Power, a Native-owned developer building utility-scale solar and storage on tribal land, with the Nation sharing in the ownership. Its Painted Desert Power project is 750 megawatts on nearly 5,000 acres, one of the largest solar and battery projects in the Southwest, and the first commercial lease for a utility-scale project on the Navajo Nation. Its residential arm, Navajo Power Home, has put solar and batteries on more than 600 homes, with a goal of 3,000 by 2031. The first money behind it was not bank money. It was impact investors and foundations: Candide Group, the W.K. Kellogg Foundation, the Sierra Club Foundation, Halloran Philanthropies, the Schmidt Family Foundation, and sixteen CataCap donors who have put more than $360,000 into the Navajo Power fund. In this episode: The elder in Shonto who had no light bulbs, so the first proof her house had power was the refrigerator light, after years of keeping food on dry ice Why coal workers were the most skeptical customers for off-grid solar, and what changed their minds Nicole Horseherder, the Navajo matriarch and activist who was the toughest skeptic of Painted Desert, and how she became a supporter The Turquoise Share: how Navajo Power gives communities equity in the developer instead of handing them a power plant and its liabilities What Brett got wrong early on, and why eight years of development on tribal land opens the door for every other tribe What he would tell a friend with a donor-advised fund who has never made an impact investment Brett's line to remember: "Your light switch at some point is tied to one of our facilities."
