At BESIX, we are actively supporting the transition to a low-carbon society by reducing both direct and indirect emissions across our operations. One way we’re addressing indirect emissions is by implementing more sustainable energy solutions to power our construction sites. In Belgium, two recent initiatives highlight our progress in this area.
Smarter Energy at Liv – De Molens, Deinze
On the Liv – De Molens housing project in Deinze, the team has introduced an innovative smart battery pack system to better manage energy consumption on site. Developed in partnership with Belgian start-up Bright Energy, the system offers a cleaner alternative to traditional diesel generators. These smart, easy-to-install battery units are designed specifically for construction environments.
“The batteries store energy during off-peak hours and release it during high-demand periods, particularly when operating heavy machinery or tower cranes”, explains Emmanuel Cornille, Project Manager at BESIX. “This approach not only reduces dependency on high-voltage grid connections but also cuts emissions and operational costs.”
Equipped with programmable timers and detailed monitoring features, the system ensures energy is used only when necessary, and helps teams track and optimise their consumption.
“It’s a win on all fronts,” adds Emmanuel Cornille. “Not only does this help us meet our sustainability targets, it also gives us better control over energy use on site – which translates into real cost savings.”
Solar Power at Strijderslaan, Hamme
In Hamme, BESIX Infra is working for client Aquafin on the Strijderslaan road rehabilitation project.
“As part of our effort to test eco-friendly and innovative solutions, the site office is now powered by solar panels installed on its roof,” explains Thomas Eilers, ESG Coordinator. “They are combined with a battery system to store and maximise the use of locally produced green energy.”
Similar solar-powered setups are already in place at other projects, including the R4WO ring road in Ghent, reflecting BESIX’s wider commitment to renewable energy. “The system allows us to monitor real-time data on energy production, consumption, emissions, and cost savings – many insights that we can apply to future sites!”
In addition, the Hamme site is expanding the use of electric construction equipment. Alongside an electric roller, the team has introduced two new battery-powered machines: a rammer and a core drill. After an initial hands-on training session, the team quickly got to work testing the equipment under real site conditions.
“This site is also a platform for open dialogue with our client, Aquafin, as we explore shared strategies for more sustainable site operations,” adds Thomas. “At the same time, it provides valuable practical experience in applying the CO₂ performance ladder at site level.”
