ZBB Energy Corporation - Clean Air Through Energy Efficiency
CATEE Presentation December 2008 Example Presentation April 2008 ZBB ENERGY CORPORATION ZBB Snapshot To become the leader in large capacity energy storage solutions Our energy storage solutions address issues related to grid stability and renewable energy intermittency. o Distributed storage of electrical energy during off peak periods. Re‐supply on high demand providing grid reliability and economic benefits. o Smoothing / shifting intermittent renewable energy generation. Controlled generation, grid stability and optimal use o Enabling energy independence and RAPS o Green back up power and power quality. ZBB ‘s technology fits hand‐in‐hand with alternative energy growth and deployment.
