Dutch-German transmission system giant TenneT is preparing to raise equity through third-party investors, and both a private investment deal or a stock market flotation for TenneT Germany are being considered.

The TSO published a public notice in the Financial Times Tuesday calling for interested private investors to contact the company’s financial advisors by March 25 to receive additional information on TenneT Germany and the process.

The investor search and now publicly stated consideration for an IPO comes after efforts by Germany’s government abandoned efforts to take over TenneT Germany through its development bank KfW.

After Germany had boosted its offshore wind target to 70GW by 2045 — a volume requiring massive financial resources — TenneT’s management as well as the Dutch state, which owns the company, had said the required financing would be too large for it to bank.

The proposal was supported by outgoing Green Party climate and energy minister Robert Habeck, who said it would facilitate long-term planning and investment for the country’s much-needed grid expansion, but budget constraints that eventually led to the collapse of the German government put an end to the take-over plans last year.
An IPO of the German unit could be valued at €20bn ($21.8bn), the Financial Times had said in October, citing people familiar with the matter.

TenneT operates more than 25,000km of high voltage connections in Germany and the Netherlands, among them the Dutch and German offshore wind grid links.

Despite a change in the Netherlands to a less renewables-friendly government and the end of Germany’s Social Democrat-Green-Liberal government, TenneT last year invested €10.6bn in onshore and offshore grid expansion projects, 38% more than in 2023.
