A major utility transmission company set out to evaluate two emerging battery technologies that are shaping the future of grid-scale storage—and likely to become foundational elements of tomorrow’s microgrid networks.
To compare availability, round-trip efficiency, and life-cycle cost, the client installed both a Powin lithium iron phosphate (LFP) battery and a UET ReFlex Vanadium Flow Battery. For consistent and unbiased dispatch and monitoring, Generac’s ARC microgrid control system was selected as the centralized energy management solution. Its ability to operate as an energy resource-agnostic platform made it ideal for side-by-side evaluation of distinct battery chemistries.
The ARC controller standardized all aspects of the test plan—enforcing safety protocols, managing charge and discharge rates, and ensuring interconnect compliance. This robust microgrid technology made it possible to simulate real-world operational scenarios under controlled conditions.
System performance data was streamed in real time to the utility’s SCADA system via DNP3, while also being locally logged in the ARC database. This dual-layered approach enabled high-resolution performance analysis and long-term data retention.
This deployment showcases how advanced microgrid systems can provide critical insight into energy storage innovation, helping utilities validate the assets that will define the next generation of distributed energy infrastructure.
