ZBB Energy Achieves Milestone

Two 550kWh modular, transportable energy storage systems by ZBB Energy Corp. of Milwaukee, Wisconsin, have successfully completed continuous grid-connected, load following reliability testing at Pacific Gas and Electric (PG&E) in California. “The performance of the system, running unattended under independent testing over the entire 40 cycles, proves the reliability and robustness of our products,” says Robert Parry, ZBB Energy’s CEO.

This represents the final stage in interfacing ZBB’s systems into the California transmission and distribution grid. The on-site testing was conducted at PG&E’s San Ramon test facility and included independent data gathering and assessment by Sandia National Laboratories.

ZBB Energy Corp. develops and manufactures distributed energy storage solutions based on its zinc-bromine rechargeable electrical energy storage technology. The modular construction of its core 50kWh product enables ZBB’s battery to be sized and packaged as a fully customized, large format, energy storage system.
