Formed in 1997 through the merger of Ohio Edison and Centerior Energy, FirstEnergy Corp. has grown into one of the largest investor-owned electric systems in the United States. The company operates through three core segments: Distribution, Integrated, and Stand-Alone Transmission. Its geographic footprint spans six states, including Ohio, Pennsylvania, New Jersey, West Virginia, Maryland, and New York. FirstEnergy manages over 24,000 miles of transmission lines and a vast distribution network, generating revenue primarily through regulated rates set by state authorities. In recent years, the company has transitioned away from competitive commodity-exposed generation to focus on grid modernization, reliability investments, and regulated infrastructure.
