Itron and Trilliant Partner to Deliver Energy Management Solution for Dominican Republic Utility

Dominican Republic energy distribution companies move to advanced metering for commercial and industrial customers

LIBERTY LAKE, Wash and REDWOOD CITY, CA.—October 31, 2011—Itron, Inc. (NASDAQ: ITRI), a leading provider of energy and water resource management solutions, and Trilliant, a global smart grid communications leader, announced today that the Dominican Corporation of State Electricity Companies selected Itron's data management system and electricity meters and Trilliant's communications system for commercial and industrial (C&I) customers in the Dominican Republic. The fully integrated solution will help the Dominican Republic-based utility improve meter reading accuracy and enhance service for its large customers.

The award was made by the Dominican Corporation of State Electricity Companies (Corporación Dominicana de Empresas Eléctricas Estatales - CDEEE), the holding company that manages the transmission and distribution companies EdeNorte, EdeSur and EdeEste.

"The Itron and Trilliant solution was one of the best choices available to help us meet our business goals," said George Reinoso, energy adviser at CDEEE. "With this flexible solution, we will be able to leverage our existing public cellular network to better manage C&I meter data, eliminate manual meter reads to reduce costs and errors, and the near real-time data will help us improve our regulatory compliance."

The partners are providing the SENTINEL® CellReader®, an under-the-glass communication solution that discourages tampering. CellReader technology will provide two-way communications between Itron's SENTINEL C&I meters and Itron's industry-leading C&I data management system. In addition, Trilliant and Itron will deploy the system and provide support and on-site training services during meter installation.

"Timely and accurate data communications are essential to smart grid initiatives," according to Arnie Liepa, Trilliant senior vice president of Channel Businesses. "The combined Trilliant and Itron offering will help CDEEE achieve greater reliability in the complex interval data required by their C&I customers."

"We are pleased to provide a tailored solution that delivers the critical knowledge to support advanced pricing programs and meet CDEEE's customer needs," said Lou Gust, Itron vice president of Sales and Marketing, Electricity. "Our partnership with Trilliant creates another flexible communication option for customers like CDEEE and demonstrates the benefits of interoperability."
