Tesvolt’s latest commercial battery storage innovation, the TESVOLT Forton, has successfully completed extensive field tests across ten customer sites, demonstrating strong revenue potential in Germany’s rapidly expanding energy trading market. According to Tesvolt AG and its subsidiary Tesvolt Energy, the outdoor storage system—designed for commercial-scale renewable energy applications—has already begun generating four- to five-figure monthly earnings for operators participating in energy trading.
High Revenues Accelerate Commercial Storage Adoption
During the multi-month field trial, Forton units deployed exclusively for power trading delivered consistent returns, validating the business case for commercial energy storage in the front-of-the-meter (FOM) segment. Companies utilizing the system for classic applications—such as peak shaving and self-consumption optimisation—also reported substantial efficiency gains.
“Energy trading is creating a gold-rush atmosphere in the energy storage industry right now,” said Johannes Mitterreiter, Managing Director of Reichbrandstätter Electrical Engineering. “My four Forton units are generating the forecasted revenues, meaning they’ll amortize within five to six years.”
Software-Driven Optimization Key to Success
Tesvolt Energy’s virtual power plant (VPP) aggregates storage assets starting from 50 kW, enabling small and mid-sized commercial systems to access lucrative spot-market trading. The company works with three of Germany’s top energy traders, ensuring competitive returns.
“Field tests allowed us to streamline the integration of new storage assets. What earlier took days now takes just half a day,” explained Juri von Wilcken, Product Manager at Tesvolt Energy. He emphasized early coordination with grid operators as a major lesson, crucial for preventing delays in commercial operation.
Advanced Battery Technology & 15-Year Guarantee
The Forton is the first Tesvolt system equipped with high-temperature cells that operate without liquid cooling—enhancing durability and enabling multiple charge cycles daily. Tesvolt offers a 15-year performance guarantee, underscoring confidence in the system’s longevity.
“Such intense daily cycling is only possible with extremely robust battery technology,” said Simon Schandert, CTO and Co-Founder of Tesvolt. The system’s intelligent software manages trading strategies to maximize revenue while protecting battery health.
Growing Demand for Trading-Ready Storage
Following the successful field tests, Tesvolt Energy is seeing rapid onboarding of new systems into its VPP.
Two-thirds of current orders are specifically for energy trading applications, noted von Wilcken. The remaining installations cater to traditional commercial use cases, which continue to deliver strong financial returns.
