About
Fluence, a joint venture between Siemens and AES, is a global market leader in energy storage solutions and AI-powered digital software for the clean energy sector. The company offers an integrated ecosystem spanning physical energy storage hardware (Gridstack, Ultrastack, Smartstack) and advanced cloud-based software applications designed to maximize the value of renewable and storage assets. At the heart of Fluence's AI offering are two key platforms: Mosaic, an intelligent bidding application that uses AI to optimize market participation for energy storage assets across major power markets including CAISO, ERCOT, and the NEM; and Nispera, an asset performance management (APM) platform that monitors and optimizes the performance of renewables and storage fleets. Fluence IQ, their underlying AI and analytics platform, powers real-time decision-making across deployed assets. With over a dozen gigawatts of AI-optimized renewables and storage under management, Fluence serves utilities, independent power producers, and large industrial energy users globally. The platform is purpose-built for enterprise energy operators who need to navigate increasingly complex grid environments, improve asset reliability, and capture maximum revenue in energy markets. Fluence operates across multiple continents and is trusted by some of the world's largest energy companies.
