A milestone for the Romanian BESS market

Repono AB (“Repono”), a European energy storage developer and operator headquartered in Göteborg, announces a strategic commercialization and optimization partnership with Gunvor Group (Geneva), in collaboration with enspired GmbH (Vienna), for its 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, Gunvor Group 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.

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

”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, is creating a strong business case for large-scale BESS assets. Together with Gunvor, enspired and our local development partner, we believe the Argeș project is exceptionally well positioned to support grid flexibility while capturing the significant opportunities offered by this evolving market environment.”
