Exelon engages in pure-play utility-scale electrical energy and natural gas transmission and distribution businesses. Having spun off its power generation assets, the company focuses exclusively on operating and maintaining physical high-voltage transmission towers, distribution poles, and underground gas pipeline network systems across multiple states. Its daily task is the physical transport of electricity and gas from upstream energy suppliers to millions of residential and commercial terminals. The business is sustained by collecting strictly government-regulated metered basic transmission fees.
