As the operator of one of Europe’s largest Virtual Power Plants, we connect thousands of energy producers, consumers, and storage systems to form a powerful team for renewable energy. We are more than just an energy trader, energy service provider, or cleantech company – we are “The Power of Many.” Our Virtual Power Plant (VPP) currently aggregates over 15,000 small and medium-sized units, including solar and biogas plants, battery storage systems, CHP units, wind farms, industrial consumers, backup generators, and power-to-X technologies. Using our central control system, we optimize the operation of these assets to ensure energy is supplied in line with demand and market conditions. Our 24/7 energy trading team brings electricity from our portfolio to European markets such as EPEX Spot and EEX. Additionally, we participate in balancing energy markets and have become the largest PV trader in Germany. But our growth goes beyond technology: we continue to welcome new team members who are curious and enthusiastic about the energy transition. “The Power of Many” is not only the driving force towards 100% renewable energy but also stands for collaboration and our shared drive to make a difference. Together, we make the energy transition possible.
