More energy. Same footprint.

This was the guiding principle behind the repowering of the photovoltaic installation in Tessera near Venice, Italy. Entering operation at the beginning of 2026, the project demonstrates how modern technology can unlock substantially higher performance from existing renewable energy infrastructure. 

The project also marks the Group’s first PV plant realized with a tracker system, broadening our expertise with this technology. 

Rather than expanding the site's footprint, Kelag International focused on maximizing the potential of the existing 1.71-hectare area. Through the replacement of the original installation with innovative bifacial PV modules and a modern tracking system, the plant's installed capacity increased from 961 kWp to 1.741 MWp. 

The result is a solar power plant capable of generating approximately 2.7 GWh of renewable electricity annually, enough to supply around 900 households with green energy. 

The upgraded installation consists of 2,742 PV modules and combines higher efficiency with improved durability and sustainability. As part of the repowering process, the existing modules were responsibly recycled, while the former static structure was replaced by a modern tracking system that enables the modules to follow the sun and optimize energy production throughout the day. 

Designed for long-term performance, the new installation can withstand wind speeds of up to 257 km/h and makes significantly better use of the available space without requiring additional land. 

Delivered end-to-end by Kelag International's team, the Tessera project highlights the growing importance of repowering as a smart and resource-efficient approach to the energy transition. It demonstrates how existing renewable energy assets can be given a second life—producing more energy, with better technology, from the very same footprint. 

With projects such as Tessera, we continue to support a more sustainable and efficient energy future across Europe.
