TotalEnergies (NYSE: TTE) and Holcim inaugurated a 31 MW floating solar power plant in Obourg, Belgium, located on a former chalk quarry site that has been converted into a lake.

The facility produces 30 GWh per year of renewable electricity for self-consumption by Holcim's industrial facilities. The companies stated it is Europe's largest floating solar power plant dedicated to self-consumption.

More than 700 meters of horizontal directional drilling were conducted to connect the solar panels to the electrical substation to maximize landscape integration, according to the press release.

"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.

TotalEnergies stated it aims to achieve over 100 TWh of net electricity production by 2030 and expects to have more than 34 GW of gross renewable power generation capacity at the beginning of 2026.

Holcim operates 26 sites in Belgium with 985 employees and is active in cement, ready-mix concrete, aggregates, and dry mortars business segments.
