TenneT to Determine Between IPO and Private Share Offering for German Transmission System Operator; German Government Contemplates Share Acquisition
TenneT's Equity Decision Looms as European Energy Giant Mulls Options
TenneT Holding, the Dutch-German transmission system operator, is gearing up to make a decision on its equity financing options in September, as it looks to support a €160 billion investment plan for grid expansion and energy transition over 2024–2033.
The company, which reported an underlying EBIT of EUR 1.5 billion in H1 2025, an increase from EUR 1 billion in the first half of 2024, is currently evaluating three main options: a private placement of shares, an initial public offering (IPO), or potential government investment.
A private placement would involve selling shares directly to institutional investors such as Caisse de dépôt et placement du Québec (CDPQ) and Apollo Global Management. This option offers more control, could help maintain TenneT’s current BBB credit rating, and avoids public market volatility, but may reduce state influence.
On the other hand, an IPO would open the company to public investors, potentially unlocking significant liquidity and attracting cornerstone investors. However, it would also expose TenneT to regulatory complexity, public scrutiny, market fluctuations, and political sensitivities in the energy sector.
The Dutch government, which owns TenneT, is yet to decide whether to sell a minority stake via a private placement or pursue a partial IPO of TenneT Germany, which could become one of Europe’s largest deals of 2025. The German government remains undecided on whether to take a direct stake in TenneT Germany, with ongoing discussions with the Netherlands but no final decision as of yet.
Meanwhile, Norway’s sovereign wealth fund is reportedly exploring a multi-billion dollar investment in TenneT Germany, indicating interest from international public investors as well.
TenneT has received significant investor interest for both the IPO and the private share placement. The company, which operates as two businesses under TenneT Holding since 1 January 2023, aims to determine in September which of the two options will be chosen and subsequently implemented.
TenneT's investments in Dutch and German onshore and offshore electricity infrastructure increased to EUR 5.5 billion in the first six months of 2025. Notably, the company recently installed its DolWin Epsilon Converter Platform and added two new converter platforms in offshore Germany, increasing the transmission capacity in the German North Sea to almost 10 GW.
The final decision on TenneT Germany's equity requirements and ownership structure remains pending, with both private placement and IPO options actively being considered. TenneT Holding will continue talks with potential investors for the private placement to get a binding offer to fulfill TenneT Germany’s capital requirements. For the IPO, the company is preparing for future discussions with investors, including potential cornerstone investors.
As TenneT looks to the future, it continues to prioritize finding a structural solution for TenneT Germany's capital requirements in 2025, with the aim of investing a total of EUR 200 billion in grid enhancements and expansion in the Netherlands and Germany by 2034.
