A public utility (usually just utility) 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.
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, but the network infrastructure used to
distribute most utility products and services has remained largely
monopolistic.
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 private 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, but 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.
