FirstEnergy owns one of the largest transmission systems in the PJM Interconnection (PJM)—a region of interconnected electricity networks—with about 24,500 miles of lines connecting the Midwest and Mid-Atlantic regions. Modernizing the transmission system is essential to building a more resilient, reliable and lower-carbon grid. Through our Energizing the Future program, we have invested nearly $6.8 billion since 2014 to upgrade our transmission system to ensure customers benefit from a smarter, stronger and more secure power grid for years to come.


Our 10 electric distribution companies form one of the nation’s largest investor-owned electric systems, serving 6 million customers in Ohio, Pennsylvania, New Jersey, West Virginia, Maryland and New York with approximately 270,000 miles of distribution lines. Our distribution business strategy is to build a more dynamic, intelligent and secure network that modernizes the way energy is delivered and provides opportunities for enhancing customer-focused services. We are deploying smart grid technologies and evaluating other emerging technologies to modernize our distribution system, meet the evolving needs and expectations of our customers, and enhance system and service reliability. 

Generation Fleet

In recent years, we have significantly reduced the size of our generation fleet. At our peak, we owned or controlled more than 23,000 MW of generating capacity. As environmental regulations and market conditions changed, the company decided to close older generating facilities, sell or retire other units and facilities, and eventually exit the competitive generation business. Accordingly, our generating fleet and associated CO2 emissions levels have been reduced significantly. FirstEnergy’s generation fleet includes just two regulated, coal-fired facilities in West Virginia (the Harrison and Fort Martin power stations), and ownership interests in pumped-storage hydro facilities in Virginia (Bath County) and New Jersey (Yards Creek)1. Together, these four facilities have 3,779 MW of generating capacity.

1 On April 6, 2020, JCP&L signed an asset purchase agreement to sell its 50% interest in the Yards Creek pumped-storage hydro generation facility in New Jersey (210 MWs), subject to closing conditions.
