Energy Vault enters Swiss market, announces new FlexGrid C&I product for 2- to 25 MW needs

Energy Vault has entered the Swiss market this week, announcing multiple battery energy storage systems (BESS) projects and deployments with new partners in the region, while also launching a new product for the commercial and industrial (C&I) sector called FlexGrid, which is designed for projects between 2-25 MW.

The new product is the B-VAULT FlexGrid which the company says is both a modular system, while remaining compact.

“With the launch of B-VAULT FlexGrid, we are introducing a compact, modular, easy-to-install, and regulation-ready platform tailored for Europe’s evolving energy landscape,” said Gianmarco Zorloni, Director of Business Development at Energy Vault.

In one of the first installations, at Schindler Group’s headquarters in Ebikon, a 2 MW / 4 MWh system incorporates custom acoustic silencers, advanced noise attenuation, and reactive power compensation, ensuring quiet operation, grid stability, and voltage optimization. Energy Vault says it fully installed, commissioned, and Swissgrid-qualified the system in less than four weeks, and was delivered at the beginning of October.

In Energy Vault’s second deployment, it will supply Energie Wettingen, an independent public utility northwest of Zurich, with an 8 MW / 16 MWh B-VAULT FlexGrid system designed for stacked, high-density deployment. Both projects will operate under CKW’s Flexpool, a diversified flexibility network in Switzerland, which aggregates more than 1,700 assets, 15 technologies, and over 1 GW of qualified capacity.

“We chose the B-VAULT FlexGrid platform from Energy Vault because of its proven product, its modularity, and its seamless integration into our grid,” said Louis Lutz, CEO of Energie Wettingen AG. “This project helps to stabilize the electricity grid in Switzerland and to optimize the management of our own energy and power capacity in Wettingen.”

Energy Vault’s Zorloni added, “These installations embody what B-VAULT FlexGrid was designed to do: deliver compact, compliant, and intelligent energy storage where it’s needed most, without compromise on performance or community impact. We look forward to continued expansion in the European market as we seek to address the continent’s evolving energy demands.”

Energy Vault added that it has opened a new service and logistics center in Central Switzerland, acting as a hub for deployments and service in wider Europe and the Middle East.
