• A plan to invest €21.5 billion in grids by 2026 was part of the 2023-2025 strategy. This evolved into a larger, more concrete plan announced in January 2026 to invest €37 billion in networks by 2028, with the specific goal of growing its Regulated Asset Base (RAB) to €70 billion.

€42 B in Investments, Iberdrola Grid and Renewables Funding

Iberdrola’s investment strategy demonstrates a clear and substantial allocation of capital toward its core businesses of regulated networks and renewable energy, de-risking its growth by focusing on stable, long-term assets. The major acquisitions and investment plans announced in 2026 represent an acceleration of the strategy outlined in prior years, with a pronounced emphasis on expanding the regulated asset base, which provides predictable, inflation-linked returns.

Strategic Acquisitions and Network Investment

The company is using large-scale M&A to accelerate its entry into new, stable markets and bolster its core grid business. The Caruna acquisition is the primary example of this, providing immediate scale in the Nordic region, a market with increasing electricity demand. This is a direct execution of the company’s long-term vision to build a portfolio of regulated assets that can balance the more variable returns from merchant renewable generation.

• The €5 billion acquisition of Finnish grid operator Caruna in July 2026 is Iberdrola’s most significant recent investment, targeting the growing electricity demand from data centers and renewables in the Nordics.
• This is complemented by a broader plan to invest approximately €37 billion in electricity networks by 2028, aiming to increase the total Regulated Asset Base (RAB) to €70 billion and solidify grids as the core of its business.

Financing the Renewable Portfolio

Alongside its grid investments, Iberdrola continues to deploy significant capital into new renewable generation across multiple technologies and geographies. The company leverages green loans and partnerships to finance this expansion, as seen with its agreements with the EIB and IFC. This ensures a steady pipeline of new projects coming online, maintaining its position as a leading global renewable energy developer.

• In Spain, the company has earmarked €5 billion for 2.5 GW of new renewable capacity, including expansion into green hydrogen and energy storage to capture additional value.
• The company’s investment in its own portfolio is evident in its capacity growth, adding 2, 370 MW of renewable assets between June 2025 and June 2026.
• To support growth in developing nations, Iberdrola signed a €300 million loan with the IFC in January 2024 to build projects in markets like Morocco and Poland.
