REDFLOW has installed the first of its megawatt-class electricity storage systems at a flat panel solar photovoltaic generation facility located at the University of Queensland.
As a demonstration control, the RedFlow-enabled photovoltaic array will be compared to an identical 390 kW PV adjacent section of the array which has no storage at all, but will face the same periodic power drops created by passing clouds.
It is hoped this comparison will show the effectiveness of large scale energy storage on managing harmonics and transient effects on the power network which could otherwise occur due to the natural fluctuations caused by solar power generation.
The system is the first in the Australian company’s planned roll-out of successive larger electricity systems in the megawatt-class. It has an installed capacity for twelve RedFlow zinc-bromine battery modules (120 kWh), coupled with power electronics rated at 30kW.
The installed prototype is packaged in a shipping container, but most of the space is being taken up by a demonstration room, with computer monitors and power meters to highlight system performance and energy flows.
According to RedFlow, it is already receiving customer interest for its MW-class electricity storage products, and the showcase unit coupled with Australia’s largest solar PV array is a great way to demonstrate its capabilities.
This installation was delayed by approximately two months as a consequence of the January 2011 floods, which affected both the RedFlow and UQ sites.
