TenneT Germany Raises €3.5 Billion in Largest-Ever Corporate EuGB-Aligned Green Bond Offering

On an unspecified date, TenneT Germany, Germany’s largest electricity transmission system operator, successfully completed its inaugural green bond offering, raising €3.5 billion, which stands as the largest corporate issuance so far under the EU’s European Green Bond (EuGB) standard; the offering saw strong investor demand with over 6x oversubscription and comprised four tranches with maturities of 4, 8, 12 and 20 years. The issuance is in line with TenneT’s Green Finance Framework released in late 2025, with proceeds earmarked for electricity transmission infrastructure and equipment investments, supporting its plan to invest around €67 billion in grid expansion from 2026 to 2030 for EU and German energy transition and renewable energy integration. Bound by the EuGB regulation (adopted in November 2023, effective December 2024), TenneT will invest proceeds in EU Taxonomy-aligned activities and adhere to strict transparency rules, while TenneT Germany’s CFO Markus Binder stated the issuance marks a milestone for independent debt market access, reflects investor confidence in its business model and energy transition role, and lays a foundation for long-term debt market presence to fund its investment plans sustainably.
