R.Power has appointed Polish EPC contractors Onde SA and Esix to build two utility-scale battery storage projects in Poland—Dziegielewo (300 MW/1200 MWh) and Gdansk (250 MW/1000 MWh)—with completion targeted for late 2027/early 2028, doubling the scale of its earlier CEE projects and bringing total BESS capacity under construction across the region to over 800 MW.

◆ ◆ The Wire takeaway
Poland's grid now has proven buyers for utility-scale battery storage at scale, and the supply chain is following: if you make thermal management, BMS software, grid interconnect hardware, or power electronics at the 250-300 MW tier, R.Power and the developers competing with them just became customers with funded, site-ready projects and hard delivery dates.
