What it does

Fluence designs and sells large battery energy storage systems, plus operating services and software that help utilities and power developers store and dispatch electricity.

Why it matters

Grid-scale and onsite batteries help data centers connect faster and smooth the sharp power swings of AI training; Fluence contributed battery storage to a Siemens reference design for NVIDIA Vera Rubin AI data centers. Most of its business is still utility and renewable storage.

How it makes money

Utilities, independent power producers and large energy users pay for battery storage systems, long-term service contracts and optimization software.

Geography

United States (Arlington, Virginia)

AI stack position

Energy and the electrical grid. The companies that generate, distribute and manage the electricity AI infrastructure runs on. AI data centers use enormous amounts of power, so the companies producing and delivering that electricity are just as critical to the AI economy as the chip makers.

Same-layer peers

Same-layer peers share an editorial stack classification; that alone does not establish direct competition.
