The European Investment Bank (EIB) has backed TenneT Germany’s inaugural €3.5 billion European Green Bond, marking the largest corporate bond issuance ever aligned with the European Green Bond Standard Regulation. The transaction also represents the EIB’s first green bond investment in Germany, reinforcing its commitment to expanding sustainable finance and supporting Europe’s clean energy transition.
As part of the landmark issuance, the EIB committed €74 million, participating in three of the four bond tranches. The investment is intended to encourage wider adoption of the European Green Bond Standard while helping mobilise additional private capital for climate and environmental projects across the European Union.
The proceeds from the bond issuance will finance the expansion and modernisation of Germany’s electricity transmission grid. Planned investments include the development of onshore and offshore high-voltage transmission infrastructure, the connection of North Sea offshore wind farms, and the integration of renewable energy into Germany’s and Europe’s wider electricity network. These projects are aligned with the EU Taxonomy for sustainable activities.
TenneT Germany issued the €3.5 billion bond across four maturities of 4, 8, 12, and 20 years. The offering attracted exceptionally strong investor demand, with subscriptions reaching approximately 6.3 times the available amount, reflecting market confidence in the company’s financial strength and its central role in Europe’s energy transition.
The bonds are listed on the regulated market of the Luxembourg Stock Exchange and are expected to be displayed on the Luxembourg Green Exchange. The issuance complies with the European Green Bond Standard Regulation as well as the 2025 ICMA Green Bond Principles.
The transaction also marks TenneT Germany’s first access to the public debt capital markets following the establishment of its new long-term ownership structure, supported by investors including APG, GIC, NBIM, and Germany’s KfW. The company plans to invest around €13 billion annually through 2030 to expand and strengthen Germany’s electricity grid infrastructure.
The EIB’s support for this record-breaking green bond highlights the growing importance of sustainable financing in accelerating Europe’s energy transition. By investing in modern transmission infrastructure, the initiative will help improve energy security, expand renewable energy capacity, and support Germany’s long-term climate and economic goals.
