TVO confirms acceptance of Olkiluoto 3 EPR and start of warranty period

20.4.2023

Teollisuuden Voima Oyj (TVO) submitted on Thursday, 20 April to the OL3 plant supplier the Provisional Takeover Certificate. In addition TVO confirmed that the commercial operation of the plant starts at 1 May 2023. This means, among others, that the capitalisation of project costs ends and the recognition of depreciation commences. The shareholders' right to the electricity produced by OL3 and their liability for the annual costs of electricity production are determined in compliance with TVO's Articles of Association.

The test production of Olkiluoto 3 ended and regular electricity production started on 16 April. The very last test production phases have now been analysed and the project has been concluded. The acceptance of the plant unit ordered under a turnkey contract has today been confirmed. The final acceptance of the plant unit will take place upon termination of the two-year warranty period. Even after that, the plant supplier's
liabilities under the warranty will remain in force to a certain extent for eight (8) years
at most.
