PGE Installs the Heart of the Energy Storage Facility in Żarnowiec
At the construction site of the Żarnowiec Energy Storage Facility, a logistics operation of rarely seen scale has begun. PGE Energia Odnawialna has received the first of 204 containerized DC-Link system units. The investment, worth PLN 1.5 billion, is scheduled for completion in 2027.
A strong local footprint – production in Biskupice Podgórne
The Żarnowiec investment is a project with a capacity of 262 MW and nearly 1 GWh (981 MWh) of energy storage. The scale of the undertaking is best illustrated by the weight of the equipment—each of the more than 200 units weighs approximately 45 tonnes. Since April 13, the containers have been systematically placed on previously prepared foundation slabs at a pace of four units per day.
One of the most important aspects of the project, emphasized by representatives of the PGE Group, is the very high level of local content. The batteries—the heart of the entire system—are not imported from Asia or the United States, but are produced in Poland.
“We are creating a full local value chain. We have launched a production line for energy storage systems built entirely locally—from electrodes, through cells, to complete units. The first mass production for PGE has just started in Biskupice Podgórne,” emphasizes Sang Hun Lee, President of LG Energy Solution Wrocław.
Cooperation with the factory near Wrocław not only optimizes logistics costs, but also provides tangible support for the domestic technology industry. Krzysztof Müller, President of PGE Energia Odnawialna, stresses that basing the investment on domestic production is a strategic choice that strengthens the Polish economy while making use of funds from the National Recovery Plan.
Technology and system safety
The Żarnowiec energy storage facility is based on DC‑Link battery technology. These are integrated container systems housing not only battery modules, but also advanced liquid cooling systems and independent fire protection systems. The equipment meets stringent European safety standards (IEC and CE).
The deployment of such a large capacity at this specific location has strong system-level justification:
- The storage facility will support the effective integration of renewable energy sources, whose share in the Polish energy mix is growing dynamically.
- The site is located near planned PGE offshore wind farms in the Baltic Sea.
- The investment neighbors the country’s largest pumped-storage power plant, creating a unique hybrid energy hub on a national scale.
According to the current schedule, deliveries of all container units are to be completed at the turn of June and July 2026. The following months will be dedicated to system integration, testing, and electrification of the facility.
