The PJM Interconnection is responsible for the day-to-day operation of the largest centrally dispatched electric system in North America. One of its foremost responsibilities is ensuring the reliable supply of energy from generating resources to wholesale customers.

PEI Power Corporation produces electricity and steam energy at its Archbald cogeneration facility. While the company sells the steam to occupants of PEI Power Park, the electricity is sold to PJM Interconnection, which resells the electricity to wholesale customers.
