In the new advanced power control center the New York Independent System Operator (NYISO) has constructed, operators work around the clock in 12-hour shifts to monitor and balance the supply and demand for power throughout the state of New York. At the heart of the new control room is an Activu-powered video wall – the largest video wall installation in the North American utility industry. The wall features 100 80-inch diagonal light-emitting diode (LED) screens that are stacked 25 wide by 4 high and span a space of 131.5 feet wide and 18.3 feet tall. At nearly 2,300 square feet, the new control center’s video wall is more than 1,000 square feet larger than the big board at NYISO’s previous facility. The center section of screens features the electric system topology of the New York Control Area, providing more than 3,000 live status points displaying line flows, line limits, transformer loading, voltages and generator output among others.
