EDF power solutions Polska and Eurus Energy Europe B.V. have announced the formation of a joint venture to develop, build and operate a utility-scale battery energy storage system in Porąbka, Poland, marking the first large-scale energy storage partnership between the two companies in the country.

Project Details and Timeline

The Kobiernice battery energy storage system will have a capacity of 120 MW and 280 MWh, making it a significant addition to Poland's emerging grid-scale storage infrastructure.

The project was initially owned and developed by EDF power solutions Polska before the joint venture was established. Construction is expected to begin shortly, with commercial operations targeted for the second half of 2027.

Partnership Structure and Rationale

The joint venture was announced, bringing together two distinct areas of expertise. EDF power solutions Polska contributes what the companies describe as a strong local presence in Poland, along with experience in developing, building, and operating battery energy storage projects. Eurus Energy Europe brings international experience as a global power producer to the arrangement.

Alicja Chilińska-Zawadzka, CEO of EDF power solutions Polska, described the deal as a pivotal moment for the project and for the broader relationship between the two companies.

"Our partnership with Eurus Energy on the Kobiernice BESS project is important in the project's life and marks a significant step forward into the rich cross-country collaboration between the two companies. It is a key step in building EDF power solutions Polska's energy storage portfolio," she said.

Hidenori Mitsuoka, Managing Director of Eurus Energy Europe, indicated that the Kobiernice project represents the company's first major move into the Polish market.

"The Kobiernice BESS project marks our first major step in Poland, where we see significant opportunities in renewable energy and energy storage markets. We look forward to further expanding the partnership between EDF power solutions and Eurus Energy Group worldwide," he said.

Poland's Grid Flexibility Needs

The two companies framed the project as a direct response to growing demand for flexibility within Poland's energy mix. According to the joint announcement, energy storage systems of this scale are intended to support system balancing, strengthen grid reliability, and facilitate further integration of renewable energy sources into the national grid.

Poland has been navigating a significant energy transition, and large-scale battery storage is increasingly seen as a critical tool for managing the variability associated with wind and solar generation.

Broader Ambitions

While the Kobiernice project is described as the first partnership of its kind between EDF power solutions Polska and Eurus Energy in Poland, comments from both executives suggest the companies view this agreement as the foundation for a wider working relationship.

Mitsuoka's reference to expanding the partnership "worldwide" points to potential collaboration beyond the Polish market, though no specific future projects were identified in the announcement.

The Kobiernice site in Porąbka positions the project within a region that already has existing energy infrastructure connections, which is a common consideration in the siting of utility-scale battery installations.

The 280 MWh energy capacity relative to the 120 MW power rating indicates a system designed for sustained discharge over an extended period, a configuration suited to grid balancing and ancillary services markets.

Powering Smarter Decisions Across Poland's Energy Landscape

With Poland's power sector undergoing one of its most ambitious transformations in decades, driven by decarbonisation targets, grid modernisation, and surging renewable investment, the cost of missing a critical project opportunity has never been higher.
