In an ambitious financial maneuver, Iberdrola has successfully raised €1.5 billion through a European senior green bond issuance, underscoring its commitment to sustainability. This move highlights growing interest in green finance, as the demand for such investments continues to surge. By strategically leveraging investor interest, Iberdrola aims to bolster its electricity grids across multiple countries and reinforce renewable energy projects, ensuring long-term benefits for both the company and its stakeholders.
In 2021, Iberdrola laid the groundwork for a shift towards a financing structure that intensifies its focus on green and sustainable products. The company’s past financial arrangements revealed an increasing alignment with sustainable practices, as evidenced by the €66 billion of sustainable financing it accumulated by the end of 2025. This progression has positioned Iberdrola among the leading corporate issuers of green bonds, marking a consistent increase in sustainable financing through renewable energy, energy efficiency, and other eco-friendly projects.
How was the demand for Iberdrola’s green bond offering?
Strong interest for Iberdrola’s issuance was evidenced by participation from over 330 international investors, with demand surpassing €4.5 billion. The sizable interest allowed Iberdrola to refine the initial pricing terms, a testament to the robust appetite for sustainable investment options in the market. As a result, this green bond issuance serves as a significant component of the company’s strategy to enhance its grid infrastructure and renewable energy portfolio.
What are the specifics of the bond issuance?
The issuance was divided into two tranches, each valued at €750 million. The first tranche will mature in June 2030 with a coupon rate of 3.125%, while the second will mature in June 2036, carrying a coupon rate of 3.75%. These tranches comply with both the ICMA Green Bond Principles and the European Union Green Bond Standard. This structured approach aligns with Iberdrola’s ongoing efforts to minimize environmental impacts and adhere to established sustainable finance criteria.
“Our objective remains to use the funds wisely to support our strategic goals,” said the company.
“The commitment to sustainability is reflected in these structured financing models,” Iberdrola stated.
Global coordinators for this significant transaction included major financial institutions such as HSBC and Santander.
This latest financial move follows Iberdrola’s €1 billion raise in October 2025 for the first-ever hybrid green bond aligned with the EuGB, demonstrating a continued pattern of leveraging innovative financial instruments to support its environmental objectives. Each initiative has progressively enabled the company to partake actively in global sustainability initiatives and market practices.
As Iberdrola continues to prioritize sustainable financial practices, its structured approach to raising funds ensures not only the advancement of its energy infrastructure but also aligns with global aspirations to reduce reliance on non-renewable resources. For investors, this signifies an opportunity to participate in a future-centric approach where financing is intricately linked with long-term ecological benefits. The success of this issuance is a clear reflection of the financial market’s readiness to support such sustainable avenues.
