Reference project

Kerschgens sustainably reduces peak loads

How is a traditional industrial company in Stolberg setting new standards for sustainable energy? The  Steel and materials trading Kerschgens shows how intelligent battery storage and local commitment can reduce peak loads, cut costs and sustainably reduce CO₂ emissions. Together with Voltfang, the industrial company is paving the way to an efficient and climate-friendly future.

charging infrastructure for electric vehicles
CO₂ reduction immediately measurable
Fewer emissions thanks to the use of requalified electric vehicle batteries.

Implemented use case

At Kerschgens, the Voltfang battery storage system ensures a stable and cost-efficient energy supply in industrial operations – even with fluctuating production requirements. At the same time, it optimizes self-consumption of the self-generated electricity and effectively reduces peak loads. The smart energy management system adapts flexibly to the specific requirements.

Aim of the project

Kerschgens aims to use energy sustainably, cut costs and reduce CO₂ emissions. Originally planned with 1 MWh, the project was successfully expanded to 2.8 MWh at the end of 2025 – a clear sign of the growing demand for energy and confidence in the technology. The installed industrial storage system will permanently increase energy efficiency and secure a sustainable energy supply in the long term. In addition, the charging infrastructure for electric vehicles is being expanded and the vehicle fleet is gradually being electrified. The project underlines the importance of innovative partnerships and sustainable storage solutions for an economic and ecological transformation.

Our customized solution

A high-performance, modular storage system with a capacity of 2.8 MWh was installed. The battery storage system consists of requalified e-car batteries and is specially tailored to Kerschgens’ requirements. The system has an output of up to 736 kW to effectively reduce peak loads and optimally increase self-consumption.
