Belgium: TotalEnergies and Holcim Inaugurate Europe’s Largest Floating Solar Power Plant Dedicated to Self-Consumption

PARIS & OBOURG, Belgium--(BUSINESS WIRE)--TotalEnergies (Paris:TTE) (LSE:TTE) (NYSE:TTE) and Holcim, a leading player in sustainable construction, inaugurated today in Belgium a floating solar power plant with a capacity of 31 MW, located in Obourg on a former chalk quarry site that has been rehabilitated into a lake.

The solar power plant produces 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. To maximize landscape integration, more than 700 meters of horizontal directional drilling were carried out to connect the panels to the electrical substation.

“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,” said Olivier Greiner, Managing Director Retail Power & Gas Belgium at TotalEnergies.
