Fluence Announces 6th Generation Energy Storage Technology

June 20th, 2020 by  

If you want an indication of where the energy storage market is heading, a recent announcement by Fluence is it. The company says it has commitments from companies like Enel, LS Power, sPower, and Siemens to install 800 megawatts/2300 megawatt-hours of battery storage using its 6th generation technology in Asia Pacific, North America, and Europe.

“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,” says Jean-Christoph Heyne, head of future grid technology at Siemens.

“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,” says Fluence CEO Manuel Perez Dubuc.

“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.”

The sixth generation systems are made possible by three innovations. Fluence IQ uses machine learning to manage battery degradation, reduce operating costs, and optimize energy market dispatch. The Fluence operating system combines comprehensive controls and asset management to improve performance at a single site or across entire fleets. Finally, Fluence Cube is a factory assembled energy storage unit that is up to 5 times more modular than traditional systems. Together, the three components allow for rapid installation and system scaling to meet the needs of individual customers.

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, which makes them simpler, safer, faster and more cost effective to deploy at scale. Fluence has three pre-configured energy storage platforms designed to meet the individual needs of customers.

  • 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.

Fluence CTO Brett Galura says, “Until now, customers were forced to choose between custom built solutions or inflexible, vertically integrated products. This sixth generation technology combines our proprietary data set 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.”

That’s good news for the energy storage sector.
