Chief Executive Officer
Mike Hall currently serves as Chief Executive Officer and board member at Anza. Mike began his career in renewable energy in 2002 when he co-founded Borrego with his brother, Aaron, and his ultimate frisbee teammate Chris Anderson. Mike’s 21-year career at Borrego included serving as the company’s CEO from 2009 to 2023. Borrego built several successful downstream solar and storage business lines during that time. One of the businesses was a leading middle-market solar, storage, and distributed wind developer. Energy Capital Partners bought that business in 2022, now New Leaf Energy. In 2020, Mike and his brother Aaron developed the initial Anza business strategy after observing Borrego’s IPP customers’ challenges in managing a rapidly changing module supply environment. Today, Mike’s focus is working with the Anza team to help the entire solar and storage industry achieve superior project outcomes. He is passionate about building high-performing teams, developing leadership, and maintaining a lean philosophy of continuous improvement—in all things related to renewable energy. Before joining Borrego, Mike worked as a Process Engineer for Applied Materials in Santa Clara. Mike holds an M.S. in Chemical Engineering from Stanford University and a B.S. in Chemical Engineering from the University of California Santa Barbara.
