The main responsibilities of a power transmission engineer revolve around planning routes for energy transmission. In this career, you play a pivotal part in the power system’s infrastructure. Your duties are to survey maps and GIS data to estimate the best path of transmission lines from the energy source (e.g. power plant) to the end user (e.g. home, building, street light, etc.). You need to be able to plan the most efficient route while simultaneously addressing safety standards and environmental laws. In addition to the planning and logistics of the power system, a power transmission engineer oversees the construction of the power system.
