If a utility plans a 345-kilovolt transmission line, a grid operator needs emergency storm hardening, or a hyperscaler wants a dedicated high-capacity substation, Quanta is on the shortlist and is often the only firm capable of delivering at scale. The company’s workforce includes more than 50,000 linemen, engineers, and technical specialists, many certified to perform the most difficult and hazardous live-line work. This specialization creates a high barrier to entry and helps explain Quanta’s record $30-billion-plus backlog.
