Silver Spring Networks Selected for AEP`s gridSMART Projects

Roll Out of Multiple Smart Grid Solutions Will Improve Efficiency and Empower
Consumers to Monitor and Control Their Energy Use

REDWOOD CITY, Calif.--(Business Wire)--
Silver Spring Networks, a leading provider of Smart Grid solutions, has been
selected by American Electric Power (NYSE: AEP) for the utility`s Smart Grid
programs at its operating companies, Indiana Michigan Power and AEP Ohio. Silver
Spring Networks is providing its field proven, IP-based technology, which
creates an end-to-end, secure and intelligent platform for the Smart Grid.

Part of AEP`s overall gridSMARTSM initiative, both projects enable multiple
Smart Grid applications over a unified network, including distribution
automation, home area networking and advanced metering. Through gridSMARTSM, AEP
will upgrade its existing energy infrastructure using Smart Grid technologies
and consumer programs. This transition will empower consumers, reduce
operational costs and enable new technologies, such as smart appliances, home
automation, plug-in hybrid electric vehicles and the integration of renewable
energy assets like wind and solar power onto the grid.

"AEP is one of the most innovative utilities in the country and we are honored
to assist them making their gridSMARTSM vision a reality," said Scott Lang,
Chairman, President and CEO of Silver Spring Networks. "By implementing an open
Smart Grid platform, AEP is ensuring it will be ready to meet its energy
efficiency challenges for generations to come."

Indiana Michigan Power initiated its Smart Meter pilot project in South Bend,
Indiana in late 2008. The initial success of that project led AEP Ohio to select
Silver Spring Networks for the expansion of its AEP Ohio gridSMARTSM
Demonstration Project in northeast central Ohio. AEP`s goal is to network 5
million homes and businesses throughout its service territory by 2015.

Silver Spring Networks` open, IP standards-based network technology allows AEP
to utilize an ecosystem of best-of-breed Smart Grid technology companies to
revolutionize the creation, distribution and consumption of energy. GE Energy,
one of the world's leading suppliers of power generation and energy delivery
technologies, will provide the smart meters and grid management software. Other
companies include S&C Electric and Cooper Power Systems which will provide
distribution automation equipment to improve grid reliability and efficiency.
