FirstEnergy Corporation and its subsidiaries are primarily engaged in the transmission, distribution, and generation of electricity across the Midwest and Mid-Atlantic regions of the United States. With a utility operating framework, FirstEnergy serves approximately 6.2 million customers across 65,000 square miles. The company operates mainly through its regulated segments: Regulated Distribution, which focuses on delivering electric services, and Regulated Transmission, which manages the infrastructure required for electricity transmission. FirstEnergy maintains a robust rate base that supports its operations through its various utility subsidiaries, including electric public utilities in Ohio, Pennsylvania, West Virginia, Maryland, New Jersey, and New York.
The business model is heavily regulated, with revenue derived predominantly from electricity service in these areas. As of 2024, FirstEnergy has consolidated its regional operations, aiming to enhance operational efficiency and potentially explore further consolidations in Ohio. The company's overall structure includes a significant transmission network and control over generation facilities, indicating a comprehensive approach to managing its electric supply, while also adapting to the evolving regulatory landscape and competitive dynamics within the energy sector.
