ZBB signs for small solar/battery project at a university in Hawaii

MILWAUKEE, WI--(Marketwired - Jul 7, 2015) - ZBB Energy Corporation (NYSE MKT: ZBB), the world's leading developer of energy management systems serving the utility, commercial and industrial building markets, signed a 20-year Power Purchase Agreement (PPA) with University of the Nations on the Island of Hawaii.

The installation will feature the industry's most advanced distributed generation system, comprised of 408kW of photovoltaic panels, Agile Hybrid batteries, and accompanying Matrix electronic power controls. In addition to providing resiliency and availability of power during grid outages, the state-of-the-art power plant and partnership with the university is expected to result in more than $2.4 million in energy savings over the lifetime of the PPA.

The University of the Nations installation is an example of how ZBB's innovative products and services are changing the way electricity is generated and managed by saving customers, like schools, commercial, and residential buildings, millions of dollars in electricity spending, while significantly reducing CO2 emissions. ZBB has recently announced and commissioned multiple grid-tied micro grid projects in Hawaii, creating numerous, unique benefits in customer-side-of-the-meter applications. ZBB's energy management system features the recently introduced Agile Hybrid Battery, the only storage system that combines the robust energy characteristics of a zinc bromide flow battery with the highly desirable power characteristics of lithium ion storage batteries in a safe, compact and economical system.

"We entered the commercial and industrial building market segment by developing the best storage and energy management platforms in the market. They are highly innovative and can simultaneously perform many power and energy applications in the most efficient manner. We implemented the PPA model into our portfolio to provide our customers with savings in electricity and our company's investors an instrument that generates a high financial rate of return over a long duration and we will continue to build our portfolio of PPAs," said Brad Hansen, President and COO of ZBB Energy. "There are hundreds of thousands of commercial, industrial and campus locations in our target markets that are paying high electricity rates or have poor power quality. Our products and services solve both problems, and do so more economically than other offerings in the market."

Founded in 1978, University of the Nations is a Christian university with branches in 600 locations in more than 140 countries. Its campus in Kona, Hawaii, is one of its largest. The installation is scheduled for completion in two phases beginning in the fourth calendar quarter of 2015, with operation pending completion of the necessary permits.
