McSally supported the Apache Solar Project in 2016. In October 2017, once construction was completed, she gave the keynote address at its dedication, calling it a "great example of member-driven co-ops, from the bottom up, figuring out ways to provide reliable power to the community, instead of top-down bureaucrats telling them what to do." She called the project a "case study" for the rest of the country in that other communities could learn how to provide customers with "low-cost, competitive renewable power."
