Iberdrola and Echelon Data Centres have closed their strategic alliance to build and operate large-scale data centres in Spain. Echelon Iberdrola Digital Infra has been created, with planned investments of more than 2 billion euros, making it the largest European joint venture between an energy company and a data centre developer.

With the completion of this transaction announced in July 2025, and after obtaining the necessary regulatory approvals, Echelon Iberdrola Digital Infra will begin its commercial activity with a focus on hyperscale technology companies and providers of infrastructure and services for artificial intelligence, a sector with great growth potential.

The first project of this alliance will be Madrid Sur, a 160,000 m² complex that will have 144 MW for data processing and already has a 230 MW electricity connection secured. This project will generate about 1,500 direct and indirect jobs and its estimated demand is 1 TWh. In addition, it will have a photovoltaic solar plant and additional renewable energy from Iberdrola to guarantee all its electricity consumption.

Keys to the agreement

Iberdrola will contribute its experience in renewable generation and in the development and management of large electricity infrastructures. It will be responsible for identifying and securing land with good connectivity to the electricity grid and ensuring a 24/7 clean energy supply. For its part, Echelon will assume the permitting, design, marketing and operation processes.

The stake in the joint venture will be up to 80% for Echelon, the rest of Iberdrola. Iberdrola has already secured more than 700 MW in electricity connections in strategic areas near Madrid and plans new projects that could add up to 6,000 million euros of investment.

With this alliance, Iberdrola reinforces its position as a key energy partner for data centres. It currently markets more than 11 TWh to technology companies and data center operators worldwide.

Spain, European digital hub

Currently, more than 70% of data traffic to Europe passes through Spain, which consolidates our country as a strategic digital hub in Europe thanks to its fibre optic network and submarine connections. Added to this are the high availability of renewable energy at competitive costs and an advanced electrical infrastructure.
