(NASDAQ: ITRI) and Silver Spring Networks announced today that they have finalized an expanded agreement to integrate Itron's CENTRON® II electricity meters, 100G gas ERT® modules and 100W water ERT® modules with Silver Spring's Smart Energy Platform. Under the terms of the agreement, the companies have addressed the technical, functional and solution delivery issues required to deliver a robust, multi-vendor advanced metering solution for gas, water and electricity providers. This further extends our existing agreement which provides for compatibility of the Itron CENTRON I electricity meter with the Silver Spring Smart Energy Platform.

"This next level of integration underscores our commitment to provide our multi-service customers expanded residential metering options," said Warren Jenson, Chief Operating Officer of Silver Spring. "Through integration of Itron's proven gas and water modules and electricity meters, Silver Spring further demonstrates the power and flexibility of IP and our Smart Energy Platform. Utility customers with a range of distribution assets will be able to manage multi-commodity metering and at the same time increase operational efficiency with a single network technology."
