Milwaukee, Wisc., March 14, 2012 — ZBB Energy Corp. won a contract from a Florida-based solar integrator to provide an integrated, continuous power ZBB EnerSystem.
This technology combines ZBB EnerStore flow-battery technology and ZBB EnerSection power and energy control capability for use in an application designed to operate in both grid-connected and transportable microgrid applications at an undisclosed U.S. military base.
The installation dovetails with a multi-year project at the base to increase energy efficiency, incorporate renewables, and increase overall energy reliability and independence with respect to the availability of the civilian grid.
As part of the Department of Defense's numerous goals relating to increasing renewable energy use, the National Defense Authorization Act of 2007 has mandated that the DOD produce or procure 25 percent of the total installation energy requirement from renewable sources.
The Florida-based integrator was awarded a demonstration grant to deploy and trial the micro-grid system using ZBB capabilities that offer a hybridized solution to integrate the mix of renewables, diesel and energy storage.
The technology will demonstrate the ability to provide a continuous power supply to local loads on the base regardless of time of day, intermittent renewables or level of stored energy, while minimizing the use of diesel fuel.
The ZBB EnerSystem will be used continuously in an ongoing operational mode in conjunction with the base grid loop, and will also demonstrate the ability to disconnect from the grid and operate as a micro-grid in 'island mode,' and then seamlessly synchronize back to the grid interconnection as appropriate. The trial at the base will monitor the overall system and will focus on the power control for micro-grid stability, power quality and minimization of fuel use.
ZBB Energy Corp. designs, develops and manufactures energy storage, power electronic systems, and engineered custom and semi-custom products targeted at the growing global need for distributed renewable energy, energy efficiency, power quality and grid modernization.
