Types of Electric Suppliers

All businesses and residential customers in the Potomac Edison service territories can shop for their electric generation supplier. The supplier you choose might be a firm located in Maryland or elsewhere in the U.S. If you decide not to choose a supplier right away, Potomac Edison will continue to supply your electricity until you do.

The following are some of the types of electric generation suppliers. 

  • Aggregator - An entity, licensed by the MdPSC that purchases electric energy and takes title to electric energy as an intermediary for a large number of consumers and to bargain on their behalf for electricity and related services. The group "aggregates" or combines customers into one large customer for purposes of negotiation. It purchases the electricity as a single customer for the group.
  • Electric Generation Supplier - A person or corporation, generator, broker, marketer, aggregator or any other entity licensed by the MdPSC that sells electricity to customers, using the transmission or distribution facilities of an electric distribution company.
  • Investor Owned Utility - A utility company owned and operated by private investors.
  • Marketer - A company, licensed by the MdPSC that buys and resells electricity, but typically does not own generating facilities.

Additional definitions can be found at the Maryland Public Service Commission (MdPAC) website.

All electric generation suppliers must be licensed by the MdPSC, including municipalities and boroughs that want to provide service outside their municipal limits. Rural electric cooperatives must have a certificate to supply service outside their areas.

All licensed suppliers will be required to furnish a bond that will ensure their financial responsibility and the supply of electricity to satisfy their contracts. Consumers who want to know if an electric supplier is licensed can check with the MdPSC or ask Potomac Edison for the MdPSC's list of licensed suppliers.
