MILWAUKEE--(Business Wire)--
Please replace the release dated July 1, 2009 with the following corrected
version due to multiple revisions.

The corrected release reads:

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.
