Energy Vault Holdings announced the launch of its FlexGrid battery energy‑storage system in Switzerland, marking the company’s first commercial deployment in the country. The FlexGrid is a new configuration of the B‑VAULT platform, engineered for 2‑25 MW industrial, commercial, and small‑utility applications with a 2‑hour duration.
The FlexGrid’s modular design allows rapid installation and scalability. In Switzerland, the company has secured a 2 MW/2‑hour system for Schindler Group’s headquarters in Ebikon, which was completed in October 2025 and qualified by Swissgrid in under four weeks. A second, larger 8 MW/2‑hour system was signed with Energie Wettingen AG, featuring a stacked configuration that delivers 8 MW of power in less than 50 square meters and will operate under CKW’s Flexpool, the country’s largest flexibility network.
This expansion positions Energy Vault to capture demand from European grid operators and commercial customers seeking long‑duration storage. The FlexGrid launch complements the company’s global B‑VAULT portfolio, which now exceeds 2 GWh of deployed or contracted capacity across Europe, North America, and Asia, and is supported by a new regional service and logistics center in Central Switzerland.
Financially, Energy Vault reported Q3 2025 revenue of $33.3 million, missing analyst forecasts but showing a year‑over‑year improvement. Earnings per share were –$0.10, below expectations, reflecting higher operating costs and investment in new markets. The company’s debt‑to‑equity ratio stands at 0.79 and its current ratio at 0.63, indicating moderate leverage and liquidity constraints, while the stock has risen 105 % year‑to‑date, underscoring investor confidence in the company’s growth trajectory.
Management highlighted the significance of the Swiss launch. Gianmarco Zorloni, Director of Business Development, said the FlexGrid “offers a compact, modular, easy‑to‑install, and regulation‑ready platform tailored for Europe’s evolving energy landscape.” Herbert Stadelmann, Head of Real Estate & Facility Management at Schindler, praised the system’s quiet operation and seamless integration with the company’s solar generation. Louis Lutz, CEO of Energie Wettingen, noted that the FlexGrid “helps stabilize the Swiss grid and optimizes the company’s own energy management.”
The announcement was well received by investors, reflecting confidence in Energy Vault’s European expansion and its ability to secure high‑profile contracts in a growing market for long‑duration storage.
