We represented Areva and Siemens in an ICC dispute against a Finnish utility company, TVO, under a contract governed by Finnish law. The dispute related to the construction of the OL3 nuclear power plant in Finland – a first of a kind third-generation nuclear plant, and the first plant of any kind to be built in Europe since the Chernobyl disaster. The dispute involved claims and counterclaims totalling in excess of €5.5 billion and presented extraordinarily complex design, regulatory, delay, and quantification issues. Three Crowns lawyers continued acting after the firm was founded and remained at the forefront on the most significant issues in the case. The dispute settled in early 2018.
