Fluence, a Siemens and AES company, has unveiled its sixth-generation energy storage technology stack combining factory-built hardware, advanced software and data-driven intelligence.
Drawing on more than 12 years of industry leadership and innovation, the new technology is changing the way energy storage systems are built and operated — making them simpler, safer, faster and more cost-effective to deploy at scale.
The technology stack creates the foundation for three purpose-built systems, Gridstack™, Sunstack™ and Edgestack™, that are configured for grid, renewable and commercial & industrial (C&I) applications, respectively, while easily addressing the need for larger systems and larger fleets of systems. Fluence has already been selected by leading customers such as Enel, LS Power, sPower and Siemens for 800 megawatts, 2300 megawatt-hours, of projects using the new technology.
Fluence’s new technology stack includes three components:
- Fluence IQ: Digital intelligence engines use data and machine learning to improve system decision-making, manage battery degradation, reduce operating costs and optimize energy market dispatch.
- Fluence Operating System (OS): Built on a decade of digital control system development, the fully integrated operating platform combines comprehensive controls, system visibility and asset management to improve asset performance at a single site or across entire fleets.
- Fluence Cube: The factory-assembled building block is 4-5x more modular than traditional systems and incorporates the latest technologies for rapid installation and scale, consistent operations & maintenance and improved quality control.
Fluence Cube, OS and IQ incorporate enhanced safety features to meet the most stringent safety standards, such as NFPA 855 and UL 9540A. Together, they provide the foundation for three pre-configured energy storage systems optimized for specific market segments and project needs:
- Gridstack: A utility-scale system designed for the most demanding grid applications (such as T&D enhancement, frequency regulation and capacity peak power), with industry-leading reliability and safety.
- Sunstack: A PV-optimized, co-located system designed to improve and expand the capabilities of solar generation with firm renewable energy delivery and additional grid services.
- Edgestack: A commercial & industrial system designed to support 500+kW applications with rapid deployment and minimum footprint to reduce demand charges and provide critical power.
Major global power suppliers and industrial customers have already committed to deploy Fluence’s sixth-generation technology in Asia Pacific, North America and Europe. Siemens is delivering Gridstack and Edgestack for customers in Germany, Portugal and Finland.
