ZBB ENERGY CORPORATION SHIPS ZESS 500 ENERGY STORAGE SYSTEM.

First Wind Energy Storage for Ireland

ZBB Energy Corporation (NYSE AMEX: ZBB) advises today that, as part of its previously announced contract with the Dundalk Institute of Technology (DIT), it has shipped a ZESS 500 system to the Republic of Ireland for inclusion in DIT’s Centre for Renewable Energy project.

This ZESS 500 zinc energy storage system has been chosen to provide key energy storage in conjunction with existing wind energy assets. The ZESS 500 will be installed alongside an existing 850kW wind turbine that is already providing half of the DIT’s power requirements. The addition of the energy storage system will maximize the viability and value of onsite wind energy.

This will be the first installation of the ZESS 500 in a wind application and will allow the campus to operate completely independently of the electrical grid. The ZESS 500 is a 500kWh ‘plug and play’ system consisting of ten of the Company’s standard 50kWh modules, together with associated power electronics and integrates with the existing power management system operating with the wind turbine.

ZBB’s Chief Executive Officer Robert Parry added “I am pleased to advise that this project was entirely on schedule and on budget, marking an important milestone for the company’s commercial success.”

In addition to this shipment, the Company also advises that it has recently shipped a ZESS 50 system to Likusasa Engineering and Contracting Pty Ltd, for their cell tower project in Zambia with MTN Group, and a ZESS 50 system to Levitate Energy for their mobile emergency power and communications centre project in Moses Lake, Washington.
