One of ATC’s applications was for $1.3m in funding to extend its use of phasor measurement units (PMUs), a new technology for monitoring the status of the grid in real time. Earlier this year, ATC installed a limited number of the PMU devices on its system.

A second ATC application for $11.4m was for funding to extend its use of fiber optics to improve communications between its electric substations and its system operations centers. ATC already has installed optical ground wire fiber on a number of its recent transmission construction projects.

John Procario, president and CEO of ATC, said: “We are pleased that these two project applications were selected. The grants give us a means to proceed with these new technologies to improve our ability to monitor the grid and enhance the reliability of our infrastructure needed to help keep the lights on.”

ATC owns, operates, builds and maintains high-voltage electric transmission system serving portions of Wisconsin, Michigan, Minnesota and Illinois.
