A 'public utility' (usually just 'utility' in British English) is a company that maintains the
infrastructure for a
public service (often also providing a service using that infrastructure). Public utilities often involve
natural monopolies, and as a result are often government monopolies, or if privately owned, the sectors are specially
regulated by a
Public Utilities Commission.
Public utilities can be
privately owned or
publicly owned. Publicly owned utilities include cooperative and municipal utilities.
Municipal utilities may actually include territories outside of city limits or may not even serve the entire city.
Cooperative utilities are owned by the customers they serve. They are usually found in
rural areas. Private utilities, also called investor owned utilities, are owned by
investors. Unlike public companies, private utilities may be listed on the
stock exchange. Private, in this context, means not owned by the
public or the
government.
In poorer
developing countries, public utilities are often limited to wealthier parts of major cities, as used to be the case in
developed countries in the nineteenth century. However, in some developing countries utilities do provide services to a large share of the urban population, such as in the case of
water and sanitation in Latin America.
Examples of utilities are:
★ An
electric utility, which in some instances can be
electric power transmission or
electricity distribution organizations.
★
Drinking water purification and distribution
★
Sewage treatment and disposal
★ Other
waste disposal
★
Natural gas distribution
★
District heat generation and distribution
★
Public transport
★
Telecomunications, such as
cable television and
telephone lines
★
Roads, including
tollways
Developments in technology have eroded some of the natural monopoly aspects of traditional public utilities. For instance,
electricity generation,
electricity retailing,
telecommunication and
postal services have become competitive in some countries and the trend towards
liberalization,
deregulation and
privatization of public utilities is growing. However, the network infrastructure used to distribute most utility products and services has remained largely natural monopolostic.
