The certification applies particularly to the development, production, installation, and maintenance of Voltfang’s energy storage systems, recognising the company’s commitment to delivering reliable energy storage solutions.
Voltfang is planning to scale production to 900 MWh annually by 2030, continuing to drive energy resilience with its battery storage solutions and supporting Europe’s green energy transition. As part of the ISO 9001:2015 certification process, Voltfang has analysed and refined its processes to meet the highest international standards. This approach enables the company to meet high standards and establish a culture of continuous improvement.
“This certification reflects our commitment to delivering energy storage solutions of the highest quality” said Afshin Doostdar, Voltfang’s CTO and Co-Founder. “It shows that we take our responsibility seriously and are committed to building future proof solutions. As we scale our operations, this certification highlights our customer and partner centricity within our processes.”
The ISO certification is the latest in a series of achievements for the Aachen-based company. In November 2024, it received the 2025 Deutscher Nachhaltigkeitspreis (German Sustainability Award) for its green battery storage solutions, recognised for their role in advancing sustainable energy use among businesses and industries. Additionally, the company just recently raised 8 million euros in Series A, being backed by prominent existing investors including PT1, AENU, Helen Ventures, Daphni, Aurum Impact, and Maximilian Viessmann.
“The certification comes at an exciting time for Voltfang, laying the foundation for significant growth over the next few years” added Roman Alberti, CSO, Co-Founder and responsible for Business Development at Voltfang. “One of our most ambitious projects involves replacing the coal power plant Weisweiler with a network of connected battery storage systems by 2030 - a move that would support Germany’s energy goals and also create a model for how regions can transition to cleaner energy.”
