Independent System Operator
Encyclopedia : I : IN : IND : Independent System Operator
In the U.S. an Independent System Operator or ISO, is a federally regulated regional organization which coordinates, controls and monitors the operation of the electrical power system.
It also acts as a marketplace in wholesale power, especially since the electricity market deregulation of the late 1990s.
Most are set up as non-profit corporations using governance models developed by the Federal Energy Regulatory Commission or FERC in April 1996.
FERC Order 888/889 required Open Access of the grid to all electricity suppliers and mandated the requirement for an Open Access Same-Time Information System (OASIS) to coordinate transmission suppliers and their customers.
The Canadian equivalent is an IEMO Independent Electricity Market Operator.
