ZBB Energy to Provide Energy Storage for Army's Micro-Grid Project

MILWAUKEE, WI--(Marketwire - Apr 4, 2011) - ZBB Energy Corporation (NYSE Amex: ZBB), the leading developer of intelligent, renewable energy power platforms, announced today a contract from Eaton Corporation to provide a 500kWH energy storage system for use in a micro-grid application at a U.S. Army facility in Ft. Sill, OK, utilizing ZBB's next generation ZESS V3 Zinc Bromide flow battery.

The demonstration at Ft. Sill is led by the U.S. Army Engineer Research and Development Center and the Construction Engineering Research Laboratory. This Department of Defense Micro-Grid Development Project will be used to develop standards for the U.S. Army's effort on the Energy Surety Micro-Grid Program. Research efforts will focus on evaluation of micro-grid technologies to provide off-grid, islanded power to specified areas at Ft. Sill. "We look forward to working with Eaton and the Army to showcase the capabilities of ZBB's third generation flow battery storage. This application is a great example of how cost effective storage will deliver multiple benefits to the Department of Defense," said Eric Apfelbach, President & CEO of ZBB Energy.

ZBB's ZESS V3 technology is a Zinc Bromide flow battery designed to serve as an advanced electrical energy storage device, constructed from environmentally-friendly materials that provide for long service life and advanced performance when compared with traditional chemical batteries.

ZBB will work closely with the Eaton's Major Projects group and the Eaton Innovation Center's design team to define operational standards for advanced energy storage systems on micro-grids such as this project and for use at future US DoD facilities.
