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

 

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.
