GOLDBECK SOLAR Polska appointed as EPC contractor for 8 MW / 16 MWh battery storage project in Poland
Under the full EPC contract, GOLDBECK SOLAR Polska will assume comprehensive responsibility for the design, procurement, construction, grid connection, system integration, testing, and commissioning of the facility. The installation will be developed as a standalone, grid-connected battery system and is expected to be among the first projects of its kind in Poland. Once operational, it will enhance grid stability, provide flexibility services, and support the continued integration of renewable energy sources into the national power system.
As part of the BESS project in Przeworsk, a medium-voltage cable connection will be built, 4 BESS battery containers with a combined capacity of 8 MW and total storage of 16 MWh installed, and 2 PCS units with transformers along with a dedicated auxiliary transformer station will be set up. The site will also feature internal roads, fencing, lighting, security systems, and noise protection for neighboring properties. Works are scheduled to start in Q2 2026, with completion and commissioning planned for the turn of Q1/Q2 2027.
The project will be executed for LC Energia, renewable energy company, Low Carbon’s majority-owned Polish entity, established in partnership with local developer Evercon and leading energy trading house InCommodities. The investment represents an important step in the expansion of utility-scale energy storage infrastructure in the Polish market.
“Battery storage will play a key role in strengthening grid stability and supporting the continued growth of renewable energy in Poland. We are proud to support LC Energia in delivering one of the early standalone BESS projects in the Polish market and to contribute our EPC expertise to this important step in the country’s energy transition” says Steffen Emmerich, Managing Director of GOLDBECK SOLAR Polska.
With growing demand for balancing services and increasing penetration of renewable energy, battery storage is becoming a critical component of Poland’s energy transition. The Przeworsk BESS project demonstrates the accelerating deployment of advanced storage solutions and highlights the role of experienced EPC contractors in delivering reliable, bankable infrastructure assets.
