Ostenweg has reached an important milestone in its flagship 126 MWp solar project in Văcărești, Romania. The installation of more than 202,000 photovoltaic modules is now complete, moving the project into the commissioning phase ahead of schedule. This achievement marks a decisive step toward bringing clean energy online for thousands of Romanian households.
The scale of the work underscores the complexity of the project. Over 27,900 piles have been driven into the ground to form a resilient foundation, while 2,265 trackers have been installed to ensure optimal solar capture. The electrical backbone is equally impressive, with 1,645 kilometers of DC cabling, nearly 44 kilometers of MV cabling, and 72 kilometers of LV cabling laid across the site. Supporting infrastructure includes 476 inverters, 17 transformer stations, and more than 50,000 square meters of newly built access roads.
With the mechanical scope completed, the project now transitions to commissioning. Activities such as string verification, insulation checks, and system integration will validate the performance and safety of the plant before its first energization. Commercial operation is expected one month earlier than initially planned, highlighting the discipline and efficiency of the delivery team.
This achievement reflects the commitment and expertise of Ostenweg’s professionals on the ground. Led by Project Manager M. Cabaza and Construction Manager I. Popovici, the team has ensured that quality, safety, and schedule remain aligned with the project’s ambitious goals.
Once operational, the Văcărești solar farm will stand as one of our largest projects, providing clean, renewable electricity while avoiding significant CO₂ emissions. The successful completion of modules installation demonstrates not only engineering precision but also the growing momentum of solar energy across the region.
