About Ontario Utilities

Ontario Utilities are business enterprises that provide essential public services including electricity, natural gas, water, and sewer services in Ontario, CA. Because of the infrastructure required to deliver services, a monopoly is often the most economical way for an utility service to operate. Ontario Public Utility Companies serve all of the customers for a particular service in Ontario.

Public & Private Utility Companies

Utilities in Ontario, California may be publicly owned enterprises or private companies. In both cases, the primary source of revenue supporting the Utility is user fees paid by customers. In the case of publicly owned Utilities, the assets of the Utility are owned by the Ontario Government Utilities Department, but it operates as a self-sustaining public enterprise supported by its own revenues rather than relying on taxes to fund operations.

Public Utilities Commissions in Ontario, California

In California, Utilities are regulated by the San Bernardino 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 Ontario consumers receive safe, reliable, and reasonably priced services from competent and financially viable companies. Ontario Utilities must receive approval for the rates they charge and they are also required to demonstrate to the Ontario Public Services Commission that they have plans to maintain an infrastructure capable of supporting current and future demand for services.

Electric Utilities

Ontario 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 San Bernardino County, CA. Therefore, transmission and distribution of electricity operates as a monopoly and customers do not have a choice when selecting their Ontario electric power company. However, the electricity in the Ontario electric grid may come from numerous suppliers.

Water Utilities

Water Utility Services in Ontario provide potable tap water directly to residential, commercial, industrial, and institutional customers through a distribution system.

Sewer Utilities

Ontario 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 San Bernardino County waterways.

Natural Gas Utilities

Ontario 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.
