Electricity production at OL2 suspended due to generator fault

Electricity production at the Olkiluoto 2 plant unit (OL2) will be suspended today, Tuesday, April 15, due to increased moisture detected in the generator of the turbine plant.

The power reduction will begin on Tuesday evening at approximately 7:00 PM. The duration of the production interruption is not yet known. The issue has no impact on nuclear safety.

The rotor of OL2's generator malfunctioned last autumn, and the unit has been operated at reduced power for several months to prevent further damage and due to a shortage of spare parts. The power output of OL2 was in the process of being restored to full capacity after the arrival of a replacement rotor at Olkiluoto.

The annual outage of Olkiluoto 2, expected to last about three weeks, is scheduled to begin on May 25.

Teollisuuden Voima Oyj has produced electricity for its shareholders, Finnish industrial and energy companies, safely and reliably for over 40 years. The island of Olkiluoto produces about 30 percent of Finland's electricity needs. Climate-friendly nuclear electricity not only benefits society but also reduces the environmental impact of energy production. Moreover, the world's first final disposal facility for spent nuclear fuel is under construction in Olkiluoto.
