This large flat-panel screen is displaying the emergency electrical circuits. The generators are at the top with building loads twoard the bottom. The emergency power is distributed at 4kV. The red/orange lines show hot (energized) circuits. The white rectangles are switches that will toggle if line power is lost. Note the seasonal decoration!
