Energy Window International (Media) – TotalEnergies said it has inaugurated, along with Holcim, described as a leading player in sustainable construction, a floating solar power plant with a capacity of 31 MW in Belgium. The plant is located in Obourg on a former chalk quarry site that was rehabilitated into a lake.
The solar power plant according to the French major will produce 30 GWh per year of renewable electricity, which is self-consumed by Holcim’s industrial facilities, making it the largest floating solar power plant in Europe dedicated to self-consumption. The firm said more than 700 meters of horizontal directional drilling were carried out to connect the panels to the electrical substation as well as to maximize landscape integration.
Olivier Greiner, Managing Director Retail Power & Gas Belgium at TotalEnergies said: “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, whom we support along with other industrial customers in their efforts to decarbonize their operations.”
TotalEnergies has described Holcim as a global leader in innovative and sustainable construction solutions. It added that the company has been promoting the development of more sustainable cities, smarter infrastructure, and improved living standards worldwide. It has also become, according to TotalEnergies, a carbon neutral company, advocating for more circular construction by using fewer resources. Holcim globally employs 45,000 people, with 985 employees across 26 sites in Belgium alone.
TotalEnergies says it is building a competitive portfolio that will combine renewables (solar, onshore wind, offshore wind) and flexible assets (CCGT, storage) to deliver clean firm power to its customers. It added that at the beginning of 2026, it has recorded more than 34 GW of gross renewable power generation capacity and aims to achieve over 100 TWh of net electricity production by 2030.
