Terra One (Berlin, 2022) develops and operates modular lithium-ion grid storage using machine learning and autonomous trading algorithms to stabilize grids, integrate renewables, and optimize market returns for utilities, municipalities, and investors.
Terra One deploys modular lithium-ion battery energy storage systems with compact, containerized designs to minimize land use and visual impact. Its control stack uses advanced machine learning and autonomous trading algorithms for real-time response to grid conditions and market signals. Systems include thermal management, grid-compliant power conversion, and safety controls for cycle life and fire mitigation. The platform supports frequency regulation, peak shaving, congestion relief, and renewable firming while reducing curtailment and enabling faster integration of variable generation into transmission and distribution networks.
Terra One delivers turnkey grid-scale battery storage projects including site acquisition, permitting, engineering, construction, and lifecycle asset management. Offerings include merchant trading services, direct marketing, long-term land lease arrangements, and operational optimization for utilities, municipalities, and investors. Primary applications are grid stabilization, ancillary services, peak shaving, congestion management, and renewable energy integration to improve system reliability and commercial returns.
In June 2025 Terra One began construction of a 15 MW / 30 MWh battery storage facility in Ahlerstedt, Germany, using its autonomous control and market participation platform to manage charging, discharging, and exchange participation. The project is intended to provide grid balancing services and commercial market revenues while demonstrating the company’s operational model for future rollouts.
Terra One has secured multiple funding rounds and institutional backing. In September 2025 it obtained up to €150 million mezzanine financing from Aviva Investors to support roughly 3 GWh of development and leverage up to €750 million in investments. Earlier, a $7.5 million seed round in early 2024 was led by PT1 and neosfer with participation from 468 Capital and others. Other investors include 468 Capital, Alpha Protocol Ventures, Andreessen Horowitz, Formulate Ventures, PT1, neosfer (Commerzbank), and private backers.
