WESTBOROUGH, Mass.--A123 Systems, LLC announced today that its businesses focused on advanced batteries for electric grid, backup power and lead-acid replacements for commercial applications will be branded A123 Energy Solutions, combining the activities of several previous groups of A123 Systems. This new division, headquartered in Westborough Massachusetts, will continue to design, develop, and manufacture advanced lithium ion energy storage systems ranging from small industrial batteries to multi-megawatt grid-scale energy storage systems. A123 Energy Solutions will also continue to support its network of value-add channel partners, distributors and resellers for A123 Systems' industry-leading Nanophosphate® cell products.

"A123 Energy Solutions has always been focused on high performance, safe and reliable battery systems and will continue to develop new energy storage products under this new brand, which helps to distinguish our activities from the transportation division in Livonia and the technologies division in Waltham," said Bud Collins, President of A123 Energy Solutions.

With locations in Westborough, Massachusetts and St. Louis, Missouri, as well as Suzhou, China, A123 Energy Solutions utilizes its state-of-the-art development centers and ISO 9001/ISO 14001 certified manufacturing facilities to design and manufacture advanced lithium ion batteries, including products like its ALM 12V7 batteries for replacing lead-acid, and its megawatt-scale Grid Storage Solution, a containerized battery system used for stabilizing the grid. As a leader in the lithium ion battery industry for stationary grid-connected energy storage systems, A123 Energy Solutions has delivered over 100 megawatts of grid battery systems, more than any other lithium ion provider in the world, and has been installing and supporting the operation of these systems since 2009, in diverse locations ranging from the Atacama desert in Chile to the island of Maui in Hawaii.

A123 Energy Solutions will unveil its new brand and showcase its industry-leading grid energy storage products at the AWEA Windpower 2013 conference, May 5-8, 2013, Chicago, IL (booth #2745).
