Gresham Smith has designed $17.7B of electric vehicle battery plants. It could be the start of a yearslong run.

The Nashville region’s largest engineering firm (and second-largest architecture firm) has created at least nine electric vehicle battery facilities in a three-year window. In that time, battery plants have gone from 0% of gross revenue to 16% of gross revenue. “I’ve been doing this 35 years. I’ve never seen anything like this, in terms of the speed and the scale and the number,” a principal said.
