Energy Vault shares surge 34.73% this week as they enter Swiss market

Energy Vault Holdings, Inc. reported a sharp rise in its share price as the company announced its formal entry into the Swiss market. The stock gained 34.73% in the past week, placing it among the week’s strongest performers in the energy sector. The company has now advanced more than 85% since the beginning of 2025.

Energy Vault develops and deploys utility-scale energy storage solutions in the United States, Australia, and other international markets. Its latest move centers on the introduction of FlexGrid, a new configuration of the B-VAULT battery energy storage system tailored for commercial and industrial users in Europe.

The company said on December 4 that it signed two agreements for FlexGrid in Switzerland. One contract is with Schindler Group, and the other is with Energie Wettingen AG. Both projects will operate under CKW Group’s Flexpool, which the company described as Switzerland’s most advanced and diversified flexibility network. Energy Vault said the agreements represent a strategic expansion of its European presence, where its B-VAULT portfolio now exceeds 2 GWh of deployed or contracted capacity across several regions.

The company stated that FlexGrid offers a compact, modular, and regulation-ready platform designed to meet evolving energy requirements in European markets. It is intended to serve industrial customers and municipal utilities across varied site conditions, including dense urban areas and larger utility-scale networks.

Gianmarco Zorloni, Director of Business Development at Energy Vault, said the launch of FlexGrid underscores the company’s ability to provide compliant and adaptable storage solutions. He said the two Swiss projects reflect the system’s capacity to address the needs of different customers while maintaining performance and limiting community impact.

Energy Vault said it will continue to expand its footprint in Europe as demand for storage solutions grows. The company noted that recent stock performance coincides with its broader international deployment activity and ongoing commercial progress.
