JUNO BEACH, Florida -- April 24, 2013

Today Silver Spring Networks, Inc. (NYSE: SSNI) joined representatives of
Florida Power & Light Company (FPL), General Electric (NYSE: GE), and the U.S.
Department of Energy in a ceremony to celebrate the success of FPL’s
pioneering ‘Energy Smart Florida’ initiative and to demonstrate the benefits
of advanced smart grid networks at FPL’s Performance and Diagnostic Center.
FPL was one of the first utilities to take a “network first” approach to grid
modernization and proactively make the infrastructure investments that today
enable greater energy efficiency and improved service reliability, while
giving customers more control over the energy they use. In the initial phase
of the multi-year ‘Energy Smart Florida’ initiative, FPL and Silver Spring
successfully connected more than 4.5 million FPL customers to the first smart
grid network of its kind, helping them reap the benefits of this
infrastructure modernization investment.

“FPL is a true industry leader – its vision to put a network at the heart of
its smart grid transformed the way the industry thinks about grid
modernization and positions FPL to continue delivering long-term innovation on
behalf of its customers,” said Daniel J. Middlleton, Executive Vice President
of Sales, Silver Spring Networks. “What started with 100,000 homes in Broward
County now serves more than 4.5 million homes and businesses across Florida.
We’re proud that millions of residents now benefit from improved service
reliability, better outage prevention and speedier restoration, and greater
ability to manage and control their energy consumption.”

“FPL and Silver Spring began this journey with the common vision that a
single, cornerstone network platform would enable a multitude of smart energy
services for our customers – and we are thrilled to have completed this
initial phase of the program ahead of schedule and in record time,” said Bryan
Olnick, FPL’s vice president of Customer Service Smart Grid Solutions. “An
open, standards-based networking platform was essential to the success of the
‘Energy Smart Florida’ program. But this is only the beginning; we now have a
foundation for a wide array of future smart grid services delivering increased
value to our customers.”

Silver Spring’s standards-based networking platform unlocks more value by
enabling multiple smart grid applications to be deployed atop a single
network. In addition to advanced energy metering, FPL is also leveraging
Silver Spring’s smart grid networking platform for Distribution Automation and
advanced Smart Grid Analytics solutions. New devices and sensors deployed on
the smart grid, and data-driven operational insights gained from innovative
analytics, expand the functionality and performance of FPL’s distribution
system, increasing reliability and reducing operations and maintenance costs.
These investments are helping FPL be much more proactive in managing its power
systems and continue improving the value FPL delivers to customers.
