FlexGen Power Systems and Rosendin have partnered to develop a utility-scale Battery Energy Storage System (BESS) that can meet the power demands of modern data centres.
The companies plan to bring to market a battery-powered system that can be used as a cheaper and faster alternative to traditional uninterruptible power supply (UPS) solutions in data centre applications.
They are performing real-world, grid-connected tests on their utility-scale ESS. Tests include investigating whether it can support mission-critical loads, enhance resiliency, and simplify transition between grid-connected and islanded modes (when the system isolates itself from the main grid in the case of a fault).
Additional tests include looking at existing grid-forming Power Conversion System (PCS) technology and how modifications to current AC PCS firmware from manufacturers can support the replacing of traditional UPSs.
The project will integrate proprietary technology and innovations from both firms.
California-based Rosendin will supply its BESSUPS design and its expertise in delivering complex electrical systems.
FlexGen will supply its battery energy storage solution and its HybridOS energy management software. This will include its Soft Grid Interconnection and Island Grid Transient Frequency Stabilization patents.
The project will further leverage FlexGen’s Innovation Lab.
Pasi Taimela, Chief Innovation Officer of FlexGen, said the partnership would bring to market a solution that is ‘a smarter, leaner, and more responsive approach to data center energy design that doesn’t require any redesigns inside the walls of the data center’.
