The Olkiluoto nuclear power station in Finland, boosted by commercial operation of a third reactor, produced 24.67 TWh of electricity in 2023, or 31% of the electricity consumed in the country, station owner and operator Teollisuuden Voima Oyj (TVO) said.
TVO said this is the highest production volume in the history of Olkiluoto and due largely to the fact that a third unit, a 1,600 EPR, began commercial operation in May.
Since it began regular electricity production in April, Olkiluoto-3 has been offline for less than four days, TVO said. The downtime was largely the result of two turbine trips in November, one of which resulted from a fault in the protection system’s measuring instrument, and the other from a turbine trip lock occurring during a nearby fault test.
