Iberdrola Moves Deeper Into AI Data Centres as Clean Power Demand Accelerates

Iberdrola is positioning itself closer to the fast-growing artificial intelligence infrastructure market, not only as a supplier of renewable electricity but also as an investor in data centre assets. The Spanish utility’s move reflects a broader question facing the energy transition: whether clean power, grids and storage can expand quickly enough to meet the electricity demand created by AI, cloud computing and digital services.

According to OneStop ESG, Iberdrola’s strategy includes taking equity in AI data centres through its joint venture with Echelon Data Centres, rather than simply selling electricity under a conventional power purchase agreement. The deal was first agreed in July 2025 and later finalised after regulatory approval. Under the structure, Iberdrola contributes land, grid connection and renewable electricity, while Echelon leads permitting, design, commercialization and operations.

Reuters reported that Iberdrola will hold a 20% stake in the joint venture, with Echelon holding the remaining 80%. The first planned project is a 160,000-square-metre complex in Spain with 144 MW of data processing capacity and a secured 230 MW electricity connection. It is expected to be operational by 2030 and to require around 1 TWh of electricity annually, supplied through a planned solar plant and additional green energy from Iberdrola.

Why Data Centres Matter for the Energy Transition

The significance of the deal lies in the scale and speed of projected electricity demand. Data centres are no longer a niche load on the power system. They are becoming a central planning issue for utilities, regulators and grid operators, particularly in markets where AI deployment is accelerating.

The International Energy Agency estimates that global data centre electricity consumption could roughly double from 485 TWh in 2025 to around 950 TWh by 2030. AI-focused data centres are expected to grow faster, with electricity consumption from those facilities tripling over the same period. The IEA also notes that data centres could account for around 3% of global electricity demand by 2030.

For utilities such as Iberdrola, this creates both an opportunity and a challenge. On one hand, hyperscale data centres can become large, long-term electricity customers, supporting investment in renewables, storage and grid connections. On the other hand, their demand is continuous and highly sensitive to reliability. AI training and inference workloads require stable power, and the sustainability benefit depends on whether new demand is matched by additional low-carbon generation rather than increasing pressure on fossil-based backup.

Iberdrola’s Investment Case

Iberdrola’s data centre move fits into a wider strategic pivot toward networks and electrification. The company has said it plans more than €100 billion of investment through 2031, including €58 billion through 2028, with around two-thirds of that amount directed to power networks. Reuters reported that the company expects its grid asset base to reach €70 billion by 2028 and more than €90 billion by 2031.

This emphasis on grids is important. Renewable generation alone is not enough to meet rising electricity demand if transmission and distribution systems cannot connect new assets, manage congestion or provide a reliable supply to large industrial and digital loads. AI data centres, electric vehicles, heat pumps and industrial electrification all add pressure to the same infrastructure.

Iberdrola’s 2025 results also provide financial context. OneStop ESG reported that the company posted €6.285 billion in net profit in 2025, up 12% year on year, while total investment reached €14.46 billion. Renewable capacity stood at 46,741 MW by the end of the first quarter of 2026, with 2,710 MW of new power and storage added in 2025.

AI as Both a Customer and a Tool

The relationship between Iberdrola and AI is not limited to powering data centres. The company is also using AI within its own energy operations. In March 2026, Iberdrola said its MeteoFlow platform had been selected by the UNESCO-linked International Research Centre on Artificial Intelligence as one of the world’s top 100 AI projects supporting sustainability. MeteoFlow uses advanced weather models and AI to forecast renewable electricity production, helping improve grid management and renewable integration.

Iberdrola also describes AI as a tool for smarter electricity networks. Its applications include predictive maintenance, outage forecasting, vegetation management using satellite imagery and better planning of network capacity. These systems can help utilities reduce interruptions, optimise existing infrastructure and integrate more variable renewable generation without immediately building new physical assets.

This dual role is central to the sector’s next phase. AI increases electricity demand, but it can also help manage the complexity created by electrification. For grid operators, the practical question is whether AI-enabled efficiency gains can meaningfully offset the new loads created by AI infrastructure itself.

Sustainability Questions Remain

Iberdrola has one of the strongest sustainability profiles among major European utilities, with science-based climate targets and a long-running focus on renewables and networks. OneStop ESG notes that the company has achieved a 20% absolute reduction in Scope 1, 2 and 3 emissions against a 2020 baseline and is working toward a 65% absolute reduction by 2030 and net-zero across the value chain by 2039.

However, the data centre strategy raises governance and system-level questions. If utilities become both power suppliers and equity investors in the data centres they serve, transparency will be important. Investors and regulators will need to understand how power allocation, pricing, grid access and capital expenditure decisions are managed.

There is also a broader sustainability issue. A data centre powered by renewable electricity can still increase total system demand. If clean generation, storage and grid capacity do not expand at the same pace, the result may be higher pressure on the wider power system, increased use of gas-fired backup or delayed decarbonisation elsewhere.

For companies in the AI and cloud sectors, the implication is clear: clean power procurement is no longer a reputational add-on. It is becoming a core infrastructure constraint. For utilities, Iberdrola’s strategy suggests a future in which supplying electricity is only part of the value chain. The larger prize may be controlling the grid-connected sites, flexible power arrangements and infrastructure partnerships that allow digital growth to remain compatible with net-zero targets.
