Public Utilities Commissions in Annapolis, Maryland

In Maryland, Utilities are regulated by the Anne Arundel County Public Services Commissions or Public Utilities Commission. Public Services Commissions are necessary when monopolies exist or in cases where competition is very limited, to ensure that Annapolis consumers receive safe, reliable, and reasonably priced services from competent and financially viable companies. Annapolis Utilities must receive approval for the rates they charge and they are also required to demonstrate to the Annapolis Public Services Commission that they have plans to maintain an infrastructure capable of supporting current and future demand for services.

Electric Utilities

Annapolis Electric Utilities are the most likely to function as a hybrid of monopoly and competitive services. Only one system for transmitting and delivering electricity to customers is feasible in a given service area such as Anne Arundel County, MD. Therefore, transmission and distribution of electricity operates as a monopoly and customers do not have a choice when selecting their Annapolis electric power company. However, the electricity in the Annapolis electric grid may come from numerous suppliers.

Sewer Utilities

Annapolis Sewer Service Companies receive wastewater from customers via sanitary sewers at a wastewater treatment plant. The Sewer Utility treats the wastewater to reduce pollutants before it is released into Anne Arundel County waterways.

Natural Gas Utilities

Annapolis Natural Gas Companies are essentially local distribution companies that deliver natural gas, received from large capacity interstate or intrastate pipelines, to individual customers through small diameter distribution pipelines.
