Polish utility PGE has started construction of the Gryfino BESS (battery energy storage system), a 400 MW / 800 MWh site near the German border, with 94 Fluence Smartstack units of 10 MWh each, ESS News reported on Oct. 27.
The project sits near the town of Gryfino, just south of Szczecin. ESS News says commercial operations are scheduled to begin in 2028. SPEC BAU Polska and El Professional will handle turnkey engineering and construction, and Fluence supplies the storage technology.
The unit count and the headline capacity do not match exactly. Ninety-four units at 10 MWh each add up to 940 MWh, against the 800 MWh project figure, and ESS News notes the project may include an overbuild to guarantee supply. Overbuild means installing more nameplate energy than the project is rated for.
The unit total is above the project figure; ESS News says the project may include an overbuild.

Why It Matters for Poland's Grid
A 400 MW / 800 MWh battery can discharge at full power for two hours. For a system with growing solar and wind output, that is capacity that can absorb midday surplus and release it in the evening peak. The sources do not describe the site's grid connection or revenue model.
Fluence said Gryfino is its third large-scale BESS (battery energy storage system) build-out in Poland, after Trzebinia and Osiek, and that it has contracted roughly 1.5 GWh of Smartstack capacity in the country. Voltgrid News reported earlier on Greenvolt's sale of two Poland battery storage projects.
Who Is Building the Gryfino Battery Project
Dawid Kliś, president of the management board at SPEC BAU Polska, said the project combines Polish engineering and construction expertise with proven global storage technology. Łukasz Stelmach, vice president of the executive board at El Professional, said the facility is underpinned by a long-term focus on safe, reliable operation. Aric Zurek, Fluence's chief of sales for future markets, called Gryfino another landmark project for storage in Poland.
What Is Still Unconfirmed on Cost and Grid Connection
ESS News said it had contacted Fluence for further information. The report does not give the project's cost, its grid connection date, the battery cell supplier or any revenue contract. The 2028 operating date comes from a single outlet's report, and the unit total of 940 MWh has not been reconciled with the 800 MWh project size by PGE or Fluence in the material available.
