Fluence, a Siemens and AES company, has unveiled its energy storage technology stack of the sixth generation combining factory-built hardware, advanced software and data-driven intelligence.

The technology stack provides the basis for three purpose-built systems, Gridstack, Sunstack and Edgestack, which are designed 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 chosen for 800 megawatts, 2300 megawatt-hours, of projects using the latest technology by leading customers such as Enel, LS Power, sPower and Siemens.

“Energy storage applications require highly flexible systems that can be tailored to specific markets and customer needs. Until now, customers were forced to choose between custom-built solutions or inflexible, vertically integrated products. This sixth-generation technology combines our proprietary dataset – among the industry’s largest – and our deep industry experience to deliver unparalleled intelligence and flexibility, while adding the benefits of mass production to standardize safety features and significantly reduce the time and cost needed to deploy energy storage. Over the past decade, Fluence has reduced the total cost of energy storage systems by 90 percent; our new technology stack focuses on driving down the non-battery costs of energy storage systems by up to 25 percent, while empowering gigawatt-sized deployments.”

 Brett Galura, CTO Fluence.

Fluence’s new technology stack includes three components:

• Fluence IQ: Artificial intelligence engines use data and machine learning to improve device decision-making, control battery depletion, reduce running costs and maximize dispatch on the energy market.
• Fluence Operating System ( OS): Based on a decade of advancement of digital control systems, the fully integrated operating model integrates robust controls, system visibility and asset management to maximize asset efficiency at a single location or across entire fleets.
• Fluence Cube: The building block constructed by the manufacturer is 4-5 times more flexible than conventional structures and integrates the latest rapid installation and scale technology, consistent operations & maintenance and increased quality control.

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.

“Battery storage is a rapidly growing segment and crucial for the energy transition. For the cost-efficient and fast execution of projects in the area of distributed energy, microgrids and eMobility infrastructure, the productization and modularization of storage technologies are decisive. With the new stack & OS approach, Fluence has a unique system providing cutting-edge safety.”

 Jean-Christoph Heyne, global head of future grids, Siemens AG.

“Cost-competitive technologies, aggressive emissions targets and increased need for grid reliability and resilience are driving global utility and C&I demand for energy storage, which BloombergNEF predicts will attract more than $560 billion in investment by 2040. What separates our carbon-intensive past from a sustainable future is market inflection. With the introduction of our next-generation design, Fluence is helping drive that inflection, making it more cost-effective, faster and safer to replace smokestacks with tech stacks that provide communities around the world with cleaner, more resilient energy systems.”
