New Orleans, LA and San Jose, CA – October 6, 2016 – Silver Spring Networks, Inc. (NYSE: SSNI) today announced that it has been selected by Entergy Services, Inc., to support the comprehensive grid modernization program of the Entergy utility Operating Companies.

In addition to advanced electricity and gas metering, the Entergy Operating Companies have the option to evaluate additional applications to be connected through Silver Spring’s platform in the future.
