with U.S. Department of Energy for Smart Grid
$12.7 million to be used to enhance smart grid within ATC footprint

PEWAUKEE, Wis.--(EON: Enhanced Online News)--American Transmission Co. has entered into two
agreements with the United States Department of Energy, accepting investment grants totaling $12.7 million to invest
in smart grid technologies to be incorporated into ATC’s transmission system.
The DOE in October notified ATC that two of its applications for smart grid investment grants were selected for
smart grid grant awards. The grants to ATC are among 100 made nationwide – totaling $3.4 billion – by the DOE to
advance smart grid technologies.
One of the grants will be used to equip ATC substations with phasor measurement units, a new technology for
monitoring the status of the grid in real time. PMUs are considered one of the most important measuring devices for
the future of power systems because they provide a wider, more integrated and time-synchronized view of the
system as a whole. ATC installed a limited number of the PMU devices on its system last year and evaluated their
performance with a positive result. A $1.3 million grant will help ATC equip remaining substations in its footprint with
the smart technology.
A second $11.4 million grant will assist in extending the use of fiber optic cable to enhance communications between
ATC’s substations and its system operations centers. ATC has installed optical ground wire on a number of recent
transmission construction projects. The more widespread use of OPGW that will be fostered by the grant will
provide ATC with a more secure and reliable data network infrastructure. The OPGW also provides a means to
transmit information from the PMUs back to the operations centers for use in system analysis.
“We are pleased to enter into these agreements and take part in the effort to more fully deploy smart grid
