This fully integrated ZESS power system will be used in an on grid configuration with simulated wind and hydro electric sources. The ZESS POWR PECC system controls energy and power inputs from multiple power sources and then delivers energy out through an integrated inverter. The OSU project is supported by the Bonneville Power Authority and Central Lincoln Public Utilities District.

ZBB's Project Manager, Mr. Christopher Kuhl said, "This project is a first of a kind trial in the United States to use energy storage as a dispatchable resource on the grid to make up for shorter duration changes in outputs from wind power. Creating effective operational models using resources like the ZESS POWR system will make wind energy a more knowable and valuable generation source."
