FirstEnergy employs a large workforce of engineers, power line and substation employees who work on our transmission and distribution system every day to ensure safe and reliable electric service to the customers in our service area.

Line workers are responsible for the construction, maintenance and repair of transmission and distribution lines, while substation electricians construct, inspect and maintain our substation equipment. Engineers and technicians who work in one of our ten operating companies ensure FirstEnergy’s substations, transformers and transmission and distribution lines are functioning properly, allowing customers to continue to receive reliable and safe electric service.
