Olkiluoto 2 to Resume Electricity Production at Reduced Capacity in October

Teollisuuden Voima Oyj´s (TVO) Olkiluoto 2 (OL2) plant unit will return to electricity production on October 6th, following the installation of a spare generator rotor. The OL2 generator rotor sustained damage in early September, and the root cause of the issue is still under investigation.

Electricity production at OL2 will initially resume at a reduced capacity of 725 MW, down from its full output of 890 MW. Because the root cause of the rotor damage is still unclear, the unit will stay on reduced power level to limit the risk of failure. This period is expected to take several months.

The spare rotor being used at OL2 is the last available in TVO’s stock. Therefore TVO operates the unit on reduced power level based on conservative analysis to ensure electricity production.

Electricity production at the Olkiluoto 1 and Olkiluoto 3 units remains unaffected and continues as normal.
