ZBB Energy Announces Agile Hybrid Series Energy Storage for Commercial and Industrial Building Market

MILWAUKEE, WI--(Marketwired - May 12, 2015) - ZBB Energy Corporation (NYSE MKT: ZBB), a leading developer of innovative energy management systems solutions serving the utility and commercial and industrial (C&I) building markets, today announced the introduction of the Agile Hybrid Series, the first energy storage system optimized specifically for high performance, safety, longevity and ability to deliver both power and energy for all available behind-the-meter applications in commercial, industrial, multi-tenant and resort buildings.

Such buildings may have 10 or more different applications for energy storage, ranging from very short UPS type applications lasting seconds or minutes, to "rate or demand shift" type applications lasting several hours and backup applications for longer term outages. To perform all of these applications requires a storage system with versatility. The frequency at which the battery is discharged can range from numerous short cycles per day for applications such as frequency regulation or renewables firming, to a single extended cycle during the day as required for "smart export" or "peak shaving". Some storage technologies are good at short discharge, high frequency cycling and some are good at deep discharge, long duration cycling. There is no battery technology that is inherently optimized for performance, longevity and safety across all potential applications. The Agile Hybrid solution is simple, economical and safe and designed with the versatility required by C&I building owners.

ZBB's hybrid storage system pairs its latest C&I Flow Battery platform, the Agile Flow Battery, with the optimum complementary storage technologies required to meet any application or set of applications required for a particular building. The Agile Flow Battery recently achieved 3^rd party certification from a leading, globally recognized test facility in China, validating that it achieved performance at or beyond design specifications and company claims.

"ZBB begins the design of nearly all our energy storage systems for the C&I market with the Agile Flow battery because it is ideally suited to applications that require discharge times greater than 2 hours. These applications form the backbone of most C&I opportunities where high financial return is possible, taking large amounts of energy from distributed generation or from the grid and moving it within the building from one time period to another, or delivering out to the grid when the utility needs it," said Brad Hansen, President and COO of ZBB Energy.
