BESIX Infra & BESIX Unitec solar plant

BESIX Infra and BESIX Unitec installed a 420 kWp solar plant in Schelle to meet Flanders' PV obligation, covering 3,700 m² of roof space with 715 panels and achieving 65% self-consumption and 30 tons of CO₂ savings annually.

Context

In response to tightening energy regulations in Flanders - particularly the PV obligation for high-consumption sites by April 1, 2026 - BESIX Infra and BESIX Unitec have taken a decisive step toward sustainability. By investing in solar energy, the companies not only comply with legal requirements but also reinforce their commitment to decarbonization and brand leadership.

Project overview

BESIX Power, in collaboration with its installation company Energieconcepten, developed, financed, and installed a 420 kWp solar power plant on the Schelle site of its subsidiaries. The installation features 715 solar panels across 3,700 m² of roof space. The system powers the entire charging park, workshops, warehouses, and offices with 100% green electricity. An intelligent curtailment system ensures optimal performance even when electricity prices drop, making the installation both flexible and future-proof.

Installing a solar plant on our buildings allows us to make substantial savings on energy bills. More importantly, it’s a strong signal to our partners and teams about the importance of reducing our carbon footprint. Our headquarters and adjacent workshop are now carbon-neutral - a major step forward.
