We are proud to announce that Symetrium is launching a new project for the modernization of I&C systems at the Porąbka-Żar pumped-storage power station – one of the most strategic and unique power facilities in Poland.
The project is being executed on behalf of PGE Energia Odnawialna by a consortium of GE Vernova and Mostostal Warszawa S.A. This marks yet another joint deployment between Symetrium and Mostostal Warszawa, building on our long-standing and fruitful cooperation on infrastructure and power projects. The investment is scheduled for completion in 2028.
The Porąbka-Żar Power Plant is a unique technological facility on the map of Poland – the first and only underground power station in Poland (with full technical infrastructure housed inside an underground cavern), located in a chamber 300 m below the summit of Mount Żar. The installed capacity of the plant is 500 MW, making it the largest energy storage facility in Poland.
It features an impressive ramp-up time to full capacity – taking just 180 seconds. It is a pumped-storage facility capable of operating in both generation and energy storage modes, providing operational flexibility depending on current grid demands. Due to its capabilities, it constitutes a critical element for stabilizing the National Power System (KSE), supporting its reliability and security.
Symetrium’s scope of work includes, among others:
- Testing and commissioning in compliance with PGE requirements,
- Implementation of modern automation solutions tailored for operation in underground infrastructure environments,
- Close cooperation with the General Contractor regarding scheduling and technical coordination.
