The Control Center for the California ISO (Independent System Operator) is the high-tech electricity traffic controller for 75 percent
of the state, directing some 200 billion kilowatt-hours of electricity annually to utilities that serve
an estimated 30 million Californians. A combination video/mosaic display system serves as
the backdrop to the Control Center and allows ISO operators to assimilate large volumes of
information in one glance.
Within this 15,000 square foot Control Center is the window to California’s electrical backbone—
a giant mosaic mapboard that gives an instant overview of where electrons are flowing throughout
the state. A total of 230,076 square tiles, each 24-millimeters in size, are snapped into place by hand
to form the imposing mapboard. Dynamic indicators show what circuits are closed or open, and
the status of key power plants and substations. This enables the ISO to monitor the security and
transmission reliability of California’s high-voltage lines, as well as those extending into neighboring
states and portions of British Columbia and Mexico.
