Bucharest / Stockholm, 21 October 2025 – Repono AB, the Sweden-based pan-European energy storage operator, has completed the acquisition of a 202 MW / 404 MWh (2.0 h) standalone battery energy storage system (BESS) project located in Argeș County, Romania. The partnership with the local developers foresees additional projects across Romania with a total combined capacity of up to 1.4 GW, reinforcing Repono’s long-term commitment to the Romanian energy storage market.

​

Developed by a Bucharest-based renewable energy developer, the project is ready-to-build and benefits from a grid connection contract with Transelectrica at the 220 kV Pitești Substation. Once operational, it will be among the largest grid-scale storage assets in Southeast Europe, capable of storing and releasing enough energy to supply more than 120,000 four-person households during peak-demand periods.

​

Gunvor, in collaboration with Enspired, the Vienna-based optimiser, will manage the offtake and market optimisation strategy, ensuring efficient integration into the Romanian and regional power markets.

​

The transaction and closing were successfully enabled with the legal support of the Romanian law firm RTPR, whose expertise ensured a smooth execution within the Romanian regulatory framework.

​

The Argeș project will play a pivotal role in enhancing grid stability, balancing renewable generation, and advancing both Romania’s and the EU’s decarbonisation goals.

​

“This transaction represents an important milestone for Repono AB and demonstrates our continued commitment to developing large-scale storage infrastructure that supports Europe’s energy transition,” said Karim Nils Grueber, CEO of Repono AB.

​

Harmen de Kool, Chairman of the Board of Repono AB, representing the leading clean tech impact investor InnoEnergy, added: “With this project, InnoEnergy’s aim to achieve carbon neutrality is further fortified. Large-scale storage assets like Argeș are key enablers of a stable and decarbonised European power system.”

​

With this acquisition, Repono AB continues to expand its pan-European portfolio of grid-scale battery energy storage systems, with active developments across Germany, Romania, Italy, Austria, and Poland, underscoring its role as a leading independent storage platform driving Europe’s renewable energy transformation.
