Status: Planning / Pre-Construction (Secured Power Connection) | Location: Madrid Sur Area, Spain (South of Madrid)
The Echelon Iberdrola Digital Infra Madrid Sur Campus is the first and flagship project arising from a landmark joint venture (JV) between Dublin-based data center developer Echelon Data Centres and Spanish energy giant Iberdrola. This collaboration, finalized in mid-2025, represents the largest European JV of its kind between a utility and a data center developer, with a planned investment exceeding €2 billion for the Spanish market. This initiative is designed to address the explosive demand for hyperscale capacity in Spain, solidifying Madrid's status as a top-tier European digital hub.
The Madrid Sur Campus is an immense undertaking, featuring a planned 160,000 square meter complex that will ultimately deliver 144 MW of IT processing capacity in its first phase. Crucially, the JV has already secured a substantial 230 MW electricity connection, an essential and often limiting factor for large-scale developments. The involvement of Iberdrola is key to this power provision; they are tasked with identifying and securing land with excellent grid connectivity and guaranteeing a 24/7 clean energy supply.
Sustainability is central to the design. The project commits to 100% renewable energy consumption, sourced partially from a planned on-site photovoltaic solar plant and additional clean energy Power Purchase Agreements (PPAs) supplied by Iberdrola. Echelon, bringing its expertise in design and operation, will manage the permitting, design, marketing, and operation processes. This energy guarantee ensures the campus adheres to the highest European environmental standards, an increasingly important factor for large cloud providers and AI companies.
Madrid's rise as a digital hub is driven by its central location in Iberia and its role as a network relay point connecting the growing number of subsea cables landing on Spain’s Atlantic and Mediterranean coasts. The Echelon Iberdrola JV, with its planned portfolio capacity of over 700 MW secured in grid connections, is a game-changer for the market, providing the large-scale, resilient, and green infrastructure necessary to position Spain as the strategic digital gateway for Southern Europe, Latin America, and North Africa.
