As part of the joint project, Electrohold Trade will manage a pool of photovoltaic systems and associated battery storage systems. In the first expansion phase, new systems with a total output of around 2.5 GWh (AC) will be integrated on an ongoing basis. Full commercial market launch is planned for the fourth quarter of 2025, with further expansion into the first quarter of 2026.
Bavarian technology meets Bulgarian market expertise
The Mobility House Energy is contributing its aggregation and trading software, which has been continuously refined since 2016 and tested with various battery technologies and numerous energy products.
Expert analysis: Key challenges and opportunities for the European renewable energy market
Electrohold Trade uses this technology to operate its energy storage systems commercially and achieve higher returns from its solar plants through advanced flexibility and intermittency trading – far beyond traditional feed-in tariff models. Together, software innovation and market experience are merging to unlock new value creation potential in Bulgaria.
Scalable model for large-scale storage projects
At the heart of the project is the co-location principle: battery storage systems are connected directly to solar parks. This close coupling allows both systems to be used optimally. Fluctuating feed-in can be better managed, grid stability is increased, and expensive grid expansion measures can be avoided. The project is a significant step for Bulgaria's energy transition and a scalable model for large-scale storage projects across Europe.
Market for hybrid power plants in Europe still in the starting blocks
Economic significance and market integration
The project establishes battery storage as a central element of Bulgaria's future energy supply and uses state-of-the-art algorithmic trading software and innovative incentive structures to exploit the full potential of renewable energies. Beyond technical innovation, the project demonstrates how classic energy trading expertise can be seamlessly integrated with state-of-the-art algorithmic trading to set new industry standards.
