Abstract

As extreme weather events and aging infrastructure continue to challenge the reliability of the electric grid, the ability to restore power as fast as possible has become a priority. At the center of this issue lies the substation, a critical and vulnerable node that houses equipment like power transformers that are large, expensive, and difficult to replace. When equipment damage occurs, especially in remote or inaccessible regions, restoration can be delayed not just by supply chain shortages[1] but also a logistics network that depends heavily on roads, rails, bridges, and ports that may not be intact or convenient.

This thesis explores the potential for hybrid airships to solve these logistical constraints and alter how utilities respond to grid emergencies. What was once regarded as obsolete technology, airships are being reinvented with updated materials, navigation systems, and efficient propulsion systems[2], [3]. Possessing the ability of vertical takeoff and landing, soft delivery, and carrying excessively heavy payloads, these bulbous aircrafts offer an ideal alternative to helicopters, trucks, cargo planes, trains, and even shipping barges.

Through comparative analysis to evaluate recent hurricanes and power system equipment transport needs, this paper argues that airships could close substantial logistical gaps in grid resilience. This thesis identifies regulatory and technical barriers to adoption while outlining a policy roadmap involving various government agencies to support integration and resilience planning.
