The Gridstream solution offers a two-way network platform that forms the
backbone for grid management solutions ranging from advanced meters to
intelligent switches, reclosers, capacitor banks and RTUs. By incorporating
the Gridstream network communication into GridSense™ monitors such as the
TransformerIQ™ and LineIQ™ solutions, utilities are able to expand their
distribution automation capabilities to full-featured overhead line and
transformer monitoring within a trusted, proven and widely deployed
intelligent communications platform. The GridSense™ LineIQ™ solution provides
intelligent overhead line monitoring, while TransformerIQ™ monitors all
failure modes in transformers from the poletop to the substation.

Utilities across the country are striving to maintain reliable, high-quality
power distribution. Advanced monitoring solutions from Landis+Gyr and
GridSense™ will simplify their task. For instance, American Electric Power
(AEP) recently chose this solution to reliably monitor end-of-line voltage in
their Public Service Company of Oklahoma Project. The GridSense™
TransformerIQ™ equipped with the Landis+Gyr Gridstream radio provides a
cost-effective, easily deployable monitoring solution.

"GridSense™ is extremely pleased to integrate the Gridstream communication
platform into our monitoring solutions," says GridSense CEO Lindon Shiao.
"Many utilities are actively using their Gridstream platform for distribution
automation and smart meter rollouts today. These utilities can now accomplish
network-wide, full-featured line and transformer monitoring more
cost-effectively and with less risk simply by leveraging their existing
communications framework. The entire team at GridSense looks forward to
serving this market."

Landis+Gyr Director of Grid Management Solutions, Kent Hedrick, acknowledged,
"Utilities are looking for ways to realize additional benefit from systems
they already have in place. Using the Gridstream platform to bring
intelligent two-way communication to the distribution grid monitoring network,
and pushing the intelligence and decision making closer to the consumer is a
win-win."
