The decision aligns with the operator's ongoing efforts to reduce emissions and improve the sustainability of its operations.
The project forms part of Aena's Climate Action Plan and is designed to generate renewable heating and cooling energy for airport facilities. According to the company, the energy produced will be equivalent to the annual consumption of approximately 1,700 households.
A key element of the initiative is the construction of up to 400 geothermal wells, each reaching a depth of around 140 metres. The underground system will harness the stable temperature of the earth to provide efficient heating and cooling, reducing reliance on conventional energy sources.
The investment represents another step in Aena's broader strategy to decarbonize its airport network and increase the use of renewable energy across its infrastructure.
Madrid-Barajas, Spain's busiest airport and one of Europe's largest aviation hubs, has been at the centre of several sustainability projects in recent years as Aena works toward its environmental objectives.
The company said the geothermal installation will contribute to lowering the airport's carbon footprint while supporting long-term energy efficiency improvements.
The announcement comes as airports across Europe continue to invest in renewable energy technologies and sustainable infrastructure projects in response to growing environmental requirements and industry-wide decarbonisation targets.
