Fluence Energy
Julian Nebreda leads Fluence Energy, the AES-Siemens joint venture that went public in 2021 and operates globally in utility-scale battery storage.
Fluence Energy
Fluence Energy was founded in 2018 through the combination of AES Energy Storage and Siemens' battery-storage business, backed by AES (a US power utility) and Siemens (a German industrial conglomerate). The firm went public on the Nasdaq in 2021 under the ticker FLNC, raising capital to expand its utility-scale battery storage footprint worldwide. The firm's strategy centers on design, supply, and lifecycle management of grid-scale battery energy storage systems, including its modular Fluence Cube platform and the Fluence IQ digital management software. Asset classes covered include utility-scale battery storage, solar-plus-storage hybrids, and ancillary grid services. Geographic operations span the United States, Canada, the United Kingdom, Ireland, Germany, Italy, and Australia. Confirmed deployments include the 300 MW/1,200 MWh Gateway Energy Storage project in California and the 200 MW/500 MWh system at the Elkhorn Battery in Moss Landing, California (per public filings, 2022). Fluence reported approximately $2.7 billion in revenue for fiscal year 2024 (per the firm's annual report, November 2024). The firm employs over 2,000 people globally, with offices in Arlington, Virginia; London, UK; Erlangen, Germany; Melbourne, Australia; and other locations. No philanthropic structures or separate investment vehicles were publicly disclosed at the time of writing. A structural differentiator is Fluence's hybrid status: a publicly traded company with substantial institutional shareholders (AES and Siemens each retain over 30%) but operating with independent management and a singular focus on energy storage technology rather than diversified energy infrastructure.

How does Fluence source its equipment?
Fluence sources battery cells primarily from suppliers in China, South Korea, and Japan. It assembles modules at factories in the United States, Europe, and Australia. Supply-chain disclosures are made in the firm's annual 10-K filing.
What is the relationship between Fluence and its founding shareholders AES and Siemens?
AES and Siemens each contributed technology and personnel at founding and remain significant minority shareholders. They are represented on Fluence's board but do not manage day-to-day operations. No exclusivity agreements prevent Fluence from working with competitors (per the firm's 2021 IPO prospectus).
Has Fluence faced regulatory or operational challenges?
In September 2022, a thermal runout event at Fluence's Elkhorn Battery in Moss Landing, California, led to a fire. The firm subsequently revised designs and implemented new safety protocols. The project resumed operation after modifications were approved by regulators (per the California Public Utilities Commission, 2023).
