"With integration of more renewable resources, changes in market design, faster synchrophase information and other changes, we understood that, for the human being, the mission was getting more complicated and complex," Legatt said. "Gary believed that the best way we can succeed is to empower our human beings to be successful, and if we empower our operators to do their best, that benefits us the most," said Mike Legatt, who was a software developer on the project at the time and now serves as ERCOT’s principal human factors engineer. It has played an integral role in ERCOT operations ever since. This visualization software offers comprehensive and customizable views of power flows, constraints and numerous other inputs, available on command, in both their control room environments and training simulations.Īn ERCOT team in 2007 completed initial development of the first Macomber Map, which upon its release was named for Gary Macomber, a human factors engineer who originally envisioned the project and died unexpectedly before its completion. Today, two grid operators are using a visualization tool, designed by their own in-house experts, that is helping their operations teams maintain that awareness more efficiently and effectively than ever before, and it is available at no cost to other entities that can benefit from this type of resource.ĮRCOT, the operator of the electric grid serving most of Texas, and Southwest Power Pool (SPP), grid operator in 14 states in the central United States, use a tool in their control rooms called the Macomber Map ® to provide a geographical depiction of their systems.
Knowing what is occurring in many places at one time - and being able to process that information quickly - is critical to the success of an electric grid operator.
