ZBB Energy and Itron, in Conjunction With Additional Project Partners, Determine Site for Project in Southern California

MILWAUKEE, WI--(Marketwire - Mar 21, 2013) - ZBB Energy Corporation (NYSE MKT: ZBB), a leading developer of intelligent, renewable energy power platforms and hybrid vehicle control systems, today offers an update to the project previously announced on September 8, 2010, taking place in conjunction with Itron, Inc. (NASDAQ: ITRI) and other complementary partners.

This project allows ZBB to demonstrate the integration of an advanced energy storage system at a yet to be publicly disclosed location in Southern California. The project is partially funded from the California Solar Initiative Research, Development, Deployment and Demonstration Program (CSI RD&D), and will provide for storage technologies to be integrated at the selected location. The objective of the project is to demonstrate the combined value of a photovoltaic (PV) energy source and energy storage.

"Based on the proactive leadership of partners for projects such as this, as well as recent announcements regarding long-term procurement goals relating to energy storage and distributed generation incentive programs in California, we are excited about size of the opportunity and near-term realization of the project, which is slated to be commissioned this summer," said Eric Apfelbach, President and CEO of ZBB Energy.
