TotalEnergies and Holcim Launch Europe’s Largest Floating Solar Power Plant in Belgium
TotalEnergies (Paris:TTE) (LSE:TTE) (NYSE:TTE) and Holcim, a global leader in sustainable construction, officially inaugurated a groundbreaking floating solar power installation in Belgium today. The new facility, located in Obourg on a former chalk quarry site that has been rehabilitated into a lake, boasts a total installed capacity of 31 megawatts (MW). This project represents a major milestone for both companies in advancing renewable energy adoption and industrial decarbonization.
The Obourg floating solar plant is designed to generate approximately 30 gigawatt-hours (GWh) of renewable electricity annually. Remarkably, all of this electricity will be self-consumed by Holcim’s industrial facilities, reducing the company’s reliance on grid electricity sourced from fossil fuels. By producing energy locally, the project not only helps cut greenhouse gas emissions but also provides Holcim with a stable and predictable supply of clean electricity, which is increasingly important amid fluctuating energy prices and growing energy security concerns in Europe.
With a capacity of 31 MW dedicated entirely to self-consumption, this floating solar power plant is now the largest of its kind in Europe. Floating solar technology has become an increasingly attractive solution for industrial and utility-scale projects, particularly in regions with limited available land. By installing panels on bodies of water such as lakes, reservoirs, and quarries, developers can avoid land-use conflicts and take advantage of natural cooling effects, which enhance solar panel efficiency and reduce water evaporation from the underlying water body.
One of the key engineering highlights of the Obourg project is the meticulous attention given to landscape and environmental integration. More than 700 meters of horizontal directional drilling were performed to connect the floating solar panels to the electrical substation. This approach minimized visual impact and environmental disturbance, ensuring that the surrounding ecosystem and local landscape were preserved. Horizontal directional drilling is a sophisticated technique often used in sensitive sites to lay electrical and utility cables underground without extensive surface excavation, which was critical for a project of this scale in a former quarry environment.
Olivier Greiner, Managing Director of Retail Power & Gas Belgium at TotalEnergies, commented on the inauguration: “We are delighted to inaugurate this floating solar power plant, which demonstrates TotalEnergies’ teams’ ability to innovate to meet the needs of our partner Holcim. We support Holcim, along with other industrial customers, in their efforts to decarbonize operations. This project exemplifies how energy transition solutions can be tailored to industrial energy consumption patterns while maximizing environmental and social benefits.”
For Holcim, this project aligns directly with the company’s broader sustainability strategy, which includes ambitious targets to reduce carbon emissions across all its operations and products. As one of the world’s leading building materials and cement producers, Holcim faces significant energy demand in its manufacturing processes. Utilizing renewable electricity generated on-site allows the company to take concrete steps toward decarbonization while maintaining operational efficiency.
The collaboration between TotalEnergies and Holcim highlights a growing trend in Europe: the integration of renewable energy directly into industrial operations. Traditionally, industrial facilities have relied heavily on electricity from the grid, which may still include a substantial share of fossil-fuel-based generation. By partnering with energy companies to develop dedicated renewable energy solutions, industrial operators can secure cost-effective, reliable, and sustainable electricity while simultaneously advancing their environmental objectives.
Floating solar technology, as demonstrated in Obourg, offers several unique advantages over traditional ground-mounted systems. Firstly, the cooling effect of water increases panel efficiency, allowing for greater electricity output per installed megawatt. Secondly, the water surface reduces the need for valuable land, making it ideal for regions where land availability is limited or where land-use conflicts exist. Finally, floating solar systems can help reduce evaporation from lakes and reservoirs, providing secondary environmental benefits, particularly in areas experiencing water stress.
This installation is part of TotalEnergies’ broader strategy to expand its renewable energy portfolio and strengthen its capabilities in industrial energy services. TotalEnergies has been actively investing in solar and other renewable technologies worldwide, focusing not only on power generation but also on delivering tailored solutions for industrial and commercial customers. The Obourg project demonstrates how TotalEnergies leverages its technical expertise, project management capabilities, and innovative approaches to meet complex energy needs while supporting the global energy transition.
For the local community and the broader renewable energy sector, the Obourg floating solar plant represents an important demonstration of how industrial energy needs and sustainability goals can coexist. By utilizing a rehabilitated quarry site, the project transforms an underused and previously extractive industrial area into a productive renewable energy hub. This approach underscores the potential for repurposing post-industrial landscapes for clean energy generation, creating value both environmentally and economically.
Looking forward, TotalEnergies and Holcim plan to monitor the performance of the Obourg plant closely and explore additional opportunities to expand floating solar installations across Europe. Lessons learned from this project—ranging from engineering design to environmental integration—will inform future deployments and help accelerate the adoption of similar solutions in other industrial settings.
The inauguration of this facility comes at a time when Europe is intensifying its efforts to meet ambitious climate and energy targets. The European Union aims to significantly increase the share of renewable energy in industrial and residential sectors while reducing greenhouse gas emissions. Projects like Obourg illustrate how industrial partnerships and innovative renewable technologies can contribute to these broader objectives.
