Project is among the largest standalone battery storage assets in Southeastern Europe

Centalion struck a commercialization and optimization partnership with Repono, a European energy storage developer and operator headquartered in Göteborg, Sweden, in collaboration with enspired GmbH (Vienna), for Repono’s flagship battery energy storage system (BESS) project in Argeș County, Romania.

The project, with an installed capacity of 202 MW / 404 MWh, is among the largest standalone battery storage assets in Southeastern Europe and comes at a time when Romania is rapidly establishing itself as one of the most attractive markets in Europe for battery energy storage. Driven by the continued expansion of renewable generation, increasing demand for grid flexibility, and a supportive regulatory framework, the Romanian power market is creating strong opportunities for large-scale storage assets to play a central role in balancing the system and enabling further renewable integration. 

Within this context, Centalion will market and commercially manage 100% of the project’s capacity via a cap and floor toll structure, while enspired GmbH will commercially optimize the asset across all existing revenue streams, providing full access to power and ancillary service markets. Together, this setup ensures that the Argeș project is well positioned to capture value across multiple revenue streams in an increasingly dynamic energy market.

Karim Grueber, Managing Director of Repono, commented:
“Romania is rapidly emerging as one of Europe’s most attractive markets for battery energy storage. The accelerated build-out of renewable generation, combined with growing system balancing requirements and increasing market volatility**Volatility** In the context of energy commodities trading, volatility refers to the degree of variation in the price of a commodity over a certain period of time. It is a... More, is creating a strong business case for large-scale BESS assets.”

“We believe the Argeș project is exceptionally well positioned to support grid flexibility while capturing the significant opportunities offered by this evolving market environment,” Grueber added.

Pawel Lewin, Head of Energy Origination & Bio Methane at Centalion, said:
“Centalion is pleased to partner with Repono in Romania, a fast-evolving power market, as we continue to explore new battery storage projects that further integration of renewable energy across the world.”

Jürgen Pfalzer, Chief Commercial Officer, enspired GmbH, said the collaboration “marks a transformative step for the deployment of large-scale storage in Romania, and we are proud to support by unlocking commercial value and boosting revenues with our advanced BESS optimization services.”

The Argeș BESS project is targeting commercial operation in Q2 2027, subject to the successful achievement of key project financing, and construction milestones.
