Press release from 07.07.2025

Combined power plant consisting of many small commercial storage systems makes the electricity grid more flexible

Distribution grid operators are receiving a large number of requests to connect large-scale energy storage systems to the medium- and high-voltage grid. This has been published by Bayernwerk Netz, Bavaria’s largest distribution system operator, and Mitnetz Strom. Due to the necessary grid expansion measures, the waiting period for applicants is usually at least five years. Start-up TESVOLT ENERGY has found a solution that can quickly connect battery storage solutions to the utility grid. It gives commerce and industry – which usually already have a sufficiently large connection to the low-voltage grid – the previously lacking incentive to connect smaller energy storage systems of 100 kWh or more to the utility grid.

TESVOLT, a leading European full-service provider of innovative energy storage solutions for public utilities and commerce, is collaborating with Samsung SDI to provide public utilities with a particularly secure, state-of-the-art battery container and comprehensive project management on site. Data servers in Germany and KRITIS-capable software are designed to effectively protect the new battery storage solution against cyber attacks. In addition, a world-first thermal runaway propagation prevention system ensures it’s a safe investment. The new SBB 1.5 battery container with 5.26 MWh storage capacity will be compatible with various European inverters and will be launched with exceptional performance and guarantee features. With the new storage solution, public utilities can also reliably provide grid services and participate in energy trading.

“Made in Europe” funding bonus for the new storage system

TESVOLT presented its new battery storage solution TESVOLT TAYTAN at the ees Europe trade fair in Munich. The system consists of battery modules that simply plug into each other – with no external cables. Between three and ten modules can be stacked, depending on the desired storage capacity. The battery modules for the new energy storage system are manufactured by TESVOLT itself in its new gigafactory in Wittenberg. This means that in future, project planners who use the TESVOLT TAYTAN can apply for the “Made in Europe” funding bonus. The battery system is designed to work with different inverters, while built-in Infineon chips protect it against cyber attack. A 12-year performance guarantee ensures investment security.

Start-up TESVOLT Energy debuts at E-world

TESVOLT, an innovation and market leader for commercial and industrial energy storage system solutions in Germany and Europe, has announced a spin-off: TESVOLT Energy. The start-up’s business model makes energy trading with battery storage systems of 100 kWh and above not only possible but profitable as well. Until now, battery storage systems of this magnitude were excluded from highly complex energy trading or only accepted on less lucrative terms. Here TESVOLT Energy is working with Germany’s most renowned traders: Enspired, Entrix and The Mobility House. The new company debuts at E-world in Essen from 11 to 13 February.

Press release from 09.09.2024

TESVOLT has announced a new joint venture, TESVOLT OCEAN. The TESVOLT Maritime Solutions division merged with Ocean Batteries from Norway last week. The innovation and market leader TESVOLT is focused on commercial and industrial energy storage solutions in Germany and Europe. Its new joint venture has developed a battery system that will enable significantly more ships in the maritime and inland shipping sector to be equipped with clean e-drives for the first time. Space in ships was often too tight for the compact battery storage systems available on the market, until now. The new “Kaptein Series” power storage system has the advantage that the battery modules can be installed individually anywhere in the ship – even on the floor. Due to its disruptive technology, the new power storage solution also features the highest energy density, the lightest weight, and the fastest charging capability on the market. This makes clean e-drives for shipping easier to implement as well as more cost-efficient.
