Amprion Secures €1.5 Billion for Grid Expansion
Amprion has raised €1.5 billion in green bonds as Germany continues to invest in the infrastructure needed to support its energy transition.
The German transmission system operator said the proceeds will exclusively finance sustainable projects aimed at expanding and upgrading the transmission grid. The transaction also completes Amprion’s bond funding for the 2026 financial year.
The financing comes as Germany’s electricity system undergoes major changes, with increasing electrification creating greater requirements for transmission infrastructure.
Two Green Bond Tranches
The issuance was divided into two equal tranches of €750 million each. The first bond has a six-year maturity and a 4.398% coupon, while the second has a 10-year maturity and a 4.838% coupon.
The bonds are listed on the Luxembourg Stock Exchange’s Euro MTF market. The transaction was arranged under Amprion’s €25 billion debt issuance programme, providing another source of funding for its long-term infrastructure investment plans.
The different maturities allow Amprion to secure financing across both medium- and longer-term periods as it continues developing its transmission network.
Funding Germany’s Energy Transition
The green bond proceeds are earmarked for sustainable projects supporting the expansion and upgrading of Germany’s transmission grid. The funding will help Amprion strengthen infrastructure needed to accommodate changes in the country’s electricity system and support the wider transition toward a more sustainable energy mix.
For Amprion, strengthening the transmission network is closely linked to Germany’s broader energy transition. As the electricity system becomes increasingly electrified, a stronger transmission network will be important for moving electricity efficiently across the country and connecting generation with areas of demand.
The latest financing therefore connects capital-market funding with large-scale infrastructure development, giving investors exposure to projects supporting the transformation of Germany’s power system. It also highlights the role green bonds can play in directing investment toward essential energy infrastructure while supporting longer-term climate and sustainability objectives.

Positive Investor Reception
The transaction also highlights continued investor interest in green debt linked to energy infrastructure and the wider energy transition. By securing €1.5 billion through green bonds, Amprion has strengthened its access to capital for projects focused on expanding and upgrading Germany’s transmission network.
Amprion CFO Peter Rüth said the company was pleased with the positive investor reception and described green Eurobonds as a key pillar of its financing strategy. The strong response from investors underlines the growing role of sustainable financing in supporting large-scale electricity infrastructure.
Dealroom reported that the €1.5 billion transaction ranks above the 95th percentile among 103 comparable deals, highlighting its size within German energy debt financing. The issuance therefore represents a significant green financing transaction as Amprion continues to secure the capital needed for its long-term investment programme.
Outlook
Amprion’s latest green bond issuance gives the company additional capital to continue expanding and upgrading Germany’s transmission network. The financing also demonstrates how green bonds can connect private capital with large-scale energy infrastructure while directing funds toward projects supporting the energy transition.
As Germany continues transforming its electricity system, the need for stronger transmission infrastructure is expected to remain central to the country’s energy plans. Access to long-term financing will therefore remain important for transmission operators seeking to deliver the infrastructure required to support a more modern and increasingly electrified power system.
For Amprion, the latest transaction strengthens its financing position while reinforcing green bonds as an important funding tool for its ongoing grid expansion and energy-transition investments.
