Rosatom–Fennovoima Arbitration: Contract Termination Found Improper, but Financial Award Favors Finland

On October 10, Russia's state nuclear corporation Rosatom and Finnish utility Fennovoima presented different interpretations of an International Chamber of Commerce arbitration ruling concerning the cancelled Hanhikivi-1 nuclear power project.

The tribunal found that Fennovoima had not been entitled to terminate the construction contract in 2022.

However, Fennovoima reported that it was entitled to reimbursement of advance payments and interest exceeding €1 billion.

After offsetting the parties' claims, the tribunal ordered Rosatom subsidiaries to pay Fennovoima approximately €606 million plus interest. Reuters

Why it matters strategically

The ruling highlights an important feature of international infrastructure contracts.

A party can lose on the legality of contract termination while obtaining a favorable net financial award.

The legal question and the economic outcome are not necessarily identical.

This matters for nuclear power projects because they involve substantial upfront capital, long development periods, licensing dependencies, and political risks that may change during construction.

The Hanhikivi-1 dispute also demonstrates how geopolitical events can undermine contracts originally designed to operate across decades.

The strategic mechanism is:

Long-term infrastructure commitment → geopolitical disruption → contract termination → arbitration → uncertain financial recovery.

For companies participating in international nuclear projects, the decision is not simply whether a contract appears legally enforceable.

It is whether the financial consequences of termination remain manageable under plausible geopolitical scenarios.
