Iberdrola announces a record €1.2 billion investment plan to upgrade Spain’s grid and enable data‑center growth
Executive summary: Iberdrola said it will resume investments in Spain with a record €1.2 billion to modernize the electricity network and support data‑center projects. The investment eases long‑standing grid bottlenecks, creates capacity for high‑power users such as data centers, and supports Spain’s energy transition and industrial policy.
Who is involved: Iberdrola (lead), Spanish government (as facilitator), potential data‑center operators and industrial customers.
Likely next: Construction of grid upgrades will begin in late 2026, with first data‑center connections expected in 2027; Iberdrola may seek additional financing or partnerships.
Iberdrola’s decision to resume investment in Spain targets the long‑standing congestion of the national electricity network, a bottleneck that has limited new large‑scale power users. By earmarking €1.2 billion for grid modernization, the utility aims to free up capacity for high‑demand customers such as data‑center operators, aligning with government objectives to boost digital infrastructure and renewable integration. The move also signals confidence in Spain’s regulatory environment, as the utility expects swift approvals given the stated public‑policy benefits.
