Silver Spring Networks and GridSense Partner on Advanced Transformer Monitoring Solution

Silver Spring Networks, Inc. (NYSE:SSNI) today announced that GridSense, Inc., an Acorn Energy company, will integrate the GridSense transformer monitoring solution with Silver Spring’s multi-application networking platform to enable more cost-effective, secure and intelligent transformer monitoring for utilities. The new offering within Silver Spring’s Grid Management solution creates mission critical intelligence for grid operation via the in-depth data captured by the GridSense transformer monitoring solution, resulting in cost savings from optimal use of grid assets and increased operational efficiencies through automation.

The integration of Silver Spring’s IPv6 networking platform and GridSense’s transformer monitoring solution means that utilities can make better grid management decisions with more precise intelligence, including energy measurement, theft detection, loading, harmonics, and fault analysis.

“We welcome GridSense to the Silver Spring Partner Program – their solution is easy to install to help utilities modernize their aging distribution infrastructure,” said Don Reeves, Executive Vice President of Engineering and Managed Services, Silver Spring Networks. “With Silver Spring’s networking platform providing continuous connectivity and data, the new solution will give utilities the ability to do continuous monitoring at the edge of the grid and send this intelligence back to the hands of the operators for immediate action, resulting in increased reliability for customers.”

“GridSense provides real-time continuous intelligence for distribution transformers to prevent overload, identify imbalances and accurately determine end of line voltage,” said Brett Sargent, President and COO of GridSense. “We are excited to partner with Silver Spring Networks, a global smart grid leader, to bring utilities enhanced reliability and efficiency to the grid.”

With more than 65 partners, the Silver Spring Partner Program is delivering comprehensive smart grid solutions, to help connect over 18.5 million IPv6-enabled devices across five continents.
