In Bulgaria, Electrohold Trade is working with The Mobility House Energy to combine solar parks and battery storage facilities based on the co-location principle. The facilities are intelligently optimized via a modern trading platform.
Battery storage sets the standard for a sustainable energy future
Electrohold Trade, a leading electricity trader and subsidiary of the Eurohold Group, is developing a high-performance pool of photovoltaic systems and battery storage facilities in Bulgaria. Systems with a capacity of around 2.5 GWh will be integrated in the first expansion phase. The market launch of these facilities is planned for the fourth quarter of 2025, with expansion planned until early 2026.
What makes this project special is its focus on the co-location principle, whereby battery storage systems are directly connected to solar parks. This allows the solar power generated to be stored flexibly on site and fed into the grid as needed. This approach increases grid stability, reduces grid expansion costs, and serves as a scalable model for further large-scale storage projects in Europe.
Technological edge through smart aggregation
The aggregation and trading software from The Mobility House Energy, which has been continuously refined since 2016, is used. The software specializes in bundling and optimizing various battery technologies, real-time data, and market dynamics.
This means that energy plants are no longer operated traditionally via fixed feed-in tariffs. Instead, the platform enables advanced flexibility trading: energy is traded dynamically, and supply and demand are optimally balanced. Algorithms ensure that yields are maximized and system services are provided for the power grid.
The integration of classic energy trading expertise with state-of-the-art algorithmic methods takes the potential of renewable energies to a new level.
"This collaboration sends a strong signal for the future of battery-based energy supply in Europe. We are proud to meet Electrohold Trade's high technological standards and honored to be their partner in this groundbreaking project. Together, we are bringing a scalable solution to life that will drive the energy transition in Bulgaria and set the pace for the whole of Europe."
