The company sits at the intersection of clean energy, grid modernization, and digital intelligence. As power grids worldwide transition toward higher penetrations of renewable energy sources such as wind and solar, the need for reliable, scalable energy storage has grown dramatically. Fluence positions itself to address this challenge by providing technology that helps utilities, developers, and commercial operators store and dispatch electricity efficiently.

What Fluence Does

Fluence's core mission centers on transforming the way power is stored and delivered, enabling a cleaner and more resilient energy future. The company designs, builds, and delivers grid-scale battery energy storage systems, and it supplements these hardware offerings with long-term service agreements and software platforms that optimize the performance and value of energy storage assets.

Energy storage plays a critical role in modern electricity grids. It helps balance supply and demand, provides backup power, smooths the intermittency of renewable generation, and supports grid stability through services such as frequency regulation and peak shaving. Fluence's products and platforms are engineered to address all of these use cases at utility and industrial scale.

Products and Hardware

Fluence offers a portfolio of energy storage product lines designed for different applications and deployment environments. These modular, factory-built systems are intended to simplify installation, reduce project risk, and accelerate time to operation.

Gridstack is Fluence's flagship grid-scale energy storage product. It is designed for large utility and infrastructure projects that require high power and high energy capacity. Gridstack supports a wide range of grid applications, including renewable integration, capacity firming, and ancillary services.

Sunstack is a product purpose-built for solar-plus-storage applications. It is optimized to pair directly with photovoltaic solar installations, allowing operators to capture excess solar generation and dispatch it when needed, maximizing the value of solar assets.

Edgestack is designed for commercial and industrial customers as well as microgrid applications. It addresses smaller-scale storage needs where flexibility and resilience are priorities.

Ultrastack is a product tailored for transmission and distribution applications, helping utilities defer or avoid costly infrastructure upgrades by deploying storage strategically on the grid.

These hardware products are built around standardized, modular designs that incorporate battery cells, enclosures, thermal management, safety systems, and power electronics. Fluence emphasizes safety and reliability across its product lines, integrating fire suppression, monitoring, and protective features into its systems.

Software and Digital Applications

Beyond hardware, Fluence has developed a significant software and digital intelligence business. The company's software platforms are designed to optimize the operation of energy storage and renewable assets in increasingly complex electricity markets.

Fluence Mosaic is an AI-enabled bidding and market participation software platform. It helps asset owners and operators automate the trading and dispatching of energy storage and renewable resources in wholesale electricity markets. By analyzing market conditions, price signals, and forecasts, Mosaic seeks to maximize revenue and value from storage assets.

Fluence Nispera is an asset performance management platform that uses data analytics and machine learning to monitor, analyze, and optimize the performance of renewable energy and storage assets. It provides operators with insights into plant health, performance trends, and maintenance needs, supporting better operational decision-making across portfolios of wind, solar, and storage facilities.

These software offerings reflect Fluence's strategy of pairing physical infrastructure with intelligent digital tools, creating recurring revenue streams and deeper customer relationships.

Services

Fluence provides comprehensive long-term service agreements to support the energy storage systems it delivers. These services are essential for ensuring that storage assets perform reliably over their operational lifetimes, which can span many years.

Service offerings include operations and maintenance, performance monitoring, warranty support, and system optimization. Fluence's service teams provide ongoing technical support, software updates, and capacity assurance, helping customers maintain the performance and availability of their assets. The company also offers augmentation services, replacing or supplementing battery capacity over time to counteract the natural degradation of battery cells.

Markets and Customers

Fluence serves a diverse customer base that includes electric utilities, independent power producers, renewable energy developers, commercial and industrial enterprises, and grid operators. The company has deployed and contracted energy storage projects across a broad geographic footprint, including North America, Europe, Asia Pacific, and other regions.

Its customers use Fluence's products to integrate renewable energy, enhance grid reliability, reduce energy costs, provide backup power, and participate in energy markets.
