Fluence

Fluence originated in January 2018 when Siemens and AES combined their energy-storage operations. The firm supplies complete battery systems and digital controls for grid and behind-the-meter applications. Products include Smartstack, Gridstack Pro and Gridstack platforms. These systems are deployed in utility-scale projects, industrial sites and data centers. Confirmed activity spans North America, Europe, Asia Pacific and Latin America. A 1 GW / 4 GWh project with LEAG in Germany was announced as the largest single storage installation for the company. Headquarters sit in Arlington, Virginia with additional offices in fifteen countries. As of March 2026 the firm reported deployed, contracted or managed assets measured in GWh and GW. No family-office or wealth-management activity appears in corporate filings or site content. Fluence operates as a commercial joint venture rather than a private investment vehicle. Ownership remains with Siemens and AES; no succession or multi-generational governance structures are disclosed.
