How will Iberdrola & Echelon Invest in Spanish Data Centres?
Spanish energy provider Iberdrola has partnered with Irish firm Echelon Data Centres to build and operate hyperscale data centre facilities across Spain, in a move that brings energy expertise and digital infrastructure under one banner.
The partnership, structured as a joint venture, is set to develop major capacity at sites selected for strong grid access and renewable energy potential.
Iberdrola, through its subsidiary CPD4Green, will hold a 20% equity share in the new data centre assets, while Echelon, backed by investment firm Starwood Capital Group, will control the remaining 80%.
Under the agreement, Iberdrola will identify sites with existing grid connections and guarantee 24/7 electricity supply.
Echelon will lead the construction, design, operation and commercialisation of the facilities.
David Mesonero Molina, Corporate Development Director at Iberdrola Group, describes the agreement as aligned with the company’s energy growth strategy.
“This agreement reinforces Iberdrola Group’s strategy to support the development of data centres, which have already become a key driver of electricity demand growth,” he says.
“The partnership signed with Echelon will allow us to leverage our portfolio of sites with grid access and our ability to supply these infrastructures with secure, clean and competitive energy 24 hours a day, 365 days a year.”
Madrid Sur: first of several hyperscale builds
The joint venture’s first development will be a large-scale data centre located in Madrid Sur, south of the Spanish capital.
The facility will span 160,000m² and deliver 144MW of IT capacity, supported by a 230MW connection to the national grid.
The site is designed to run on a mix of on-site solar photovoltaic energy and supplementary power from Iberdrola’s renewable energy portfolio.
The construction phase of the Madrid Sur campus is projected to create around 1,500 jobs.
Full operational status is expected before the end of the decade.
Annual energy consumption for the facility is forecast at 1TWh, indicating its hyperscale classification and reflecting demand from AI workloads and enterprise cloud deployments.
The choice of Madrid aligns with Iberdrola’s strategy of prioritising data centre locations with grid-ready infrastructure.
The presence of large-scale solar power capabilities nearby supports the site's renewable-first energy model, critical to meeting the energy intensity of hyperscale centres without increasing reliance on fossil fuels.
Spain’s position as a European data hub
The Iberdrola–Echelon partnership highlights Spain’s emergence as a key access point for digital infrastructure in Europe.
The country is now responsible for over 70% of data traffic entering the continent, supported by dense terrestrial fibre networks and multiple submarine cable landing stations.
These assets, combined with cost-effective renewable energy and strong build capabilities, have made Spain an increasingly attractive option for global hyperscale and cloud providers.
David Smith, Chief Investment Officer at Echelon Data Centres, points to Spain’s competitive position in the European market.
“Spain offers significant benefits for our clients: access to large-scale renewable energy at some of the lowest prices in Europe and strong construction and operational capabilities,” he says.
“Iberdrola Group is a global energy leader and we are delighted to have this opportunity to join forces to deliver world-class data infrastructure to our clients.”
Echelon is already active in the hyperscale segment in Ireland and has now extended its model into mainland Europe.
The collaboration with Iberdrola enables the company to scale faster across Spain using a ready-built energy foundation and streamlined site approval through Iberdrola’s existing property portfolio.
Renewable infrastructure supports long-term growth
Iberdrola is already supplying more than 11TWh of electricity annually to technology firms and infrastructure providers worldwide.
Its CPD4Green subsidiary manages a Spanish land bank with 700MW of permitted capacity, and a potential pipeline totalling 5,000MW.
That expansion potential positions the joint venture to scale in line with growth in AI, machine learning and cloud computing, all of which require stable, renewable-powered infrastructure.
The agreement follows a wider industry trend of tighter integration between utility firms and data centre operators, with both sectors recognising the efficiency gains and reliability benefits of cooperative infrastructure investment.
As demand grows for greener, larger-scale compute power, Spain’s blend of location, power availability and network reach is shaping it into a European gateway for data operations.
