ZBB Energy Corporation Announces Australian Sales Distribution Agreement With Zest Energy

MILWAUKEE, Oct. 21 /PRNewswire-FirstCall/ -- ZBB Energy Corporation announced today that it has entered into a sales distribution agreement with Zest Energy Pty Ltd ("Zest"), for the marketing, sale and distribution of ZBB's ZESS energy storage products in Australia and New Zealand.

Zest is an Australian company specializing in the use of regenerative fuel cells for energy storage. The company works with technology suppliers, property developers, utilities and energy users to design and install energy storage systems to reduce peak demand and energy costs, and to provide a quality power supply without the complication of diesel or gas fired generators. Zest focus on storage systems to facilitate the widespread adoption and dispatch of renewable energy generation.

Mr. Jon Pemberton, Managing Director of Zest, said, "distributed energy storage is poised to change the way we use electricity and has been described as a 'disruptive technology.' As energy prices escalate because of emissions, network constraints and rising fuel prices, energy storage will play a unique role in better utilizing existing generation and distribution assets and facilitating the introduction of renewable energy technologies. We believe that energy storage, and regenerative fuel cells in particular, will provide new opportunities for distributors, renewable generators, developers and systems integrators to meet the challenges of building a new, low emission, high efficiency energy network. We are proud to be associated with ZBB, whom we consider to be the leader in such energy storage and look forward to introducing the ZESS product to our markets." Mr. Pemberton is a former manager at Australian National Industries and Evans Deakin Industries.

Zest Co-director, Professor Tony Vassallo, said: "Energy storage will become an integral component of distributed energy systems and we are very pleased to be able to work with ZBB Energy Corporation in facilitating the uptake of this technology in Australia and New Zealand."

ZBB's Sales and Marketing Vice President, Mr. Kevin Dennis, added, "Australia is an important market region for energy storage and renewable energy. Australia has vast areas with remotely located towns, communities and mining camps, many of which rely on localized power production and distribution and are isolated from connection to its national grid. Renewable energy sources, such as solar and wind, are playing an ever increasing important role in Australia's energy future, and we know that storage is integral to that future. We are therefore delighted to appoint Zest as our representative in this market and to be working with Jon and his team."

Zest will market and distribute both ZESS 50 and ZESS 500 products manufactured and shipped from ZBB's Menomonee Falls, Wisconsin facility.
