TVO Determines Olkiluoto’s Electricity Production Problem to be Temporary

The Olkiluoto nuclear power plant in Finland, owned by Teollisuuden Voima Oy (TVO), will resume full electricity production on Wednesday, November 22 at one o’clock in the morning. This was announced by TVO to the Nordpool electricity exchange. The reactor’s electricity production had been suspended on Sunday evening.

If this happens, the decommissioning of the nuclear power plant will be reflected in the price of electricity only on Tuesday because tomorrow’s electricity will be sold in Nordpool by 2 p.m. today.

TVO’s communications manager, Johanna, stated that the company would immediately inform about any fault of the turbine plant once it is known in more detail. She did not speculate on the cause of the failure but emphasized that it was not a problem similar to last spring’s trial run but specifically a failure that occurred during use.

The Olkiluoto nuclear power plant has faced years of problems and delays since it started regular electricity production in spring 2017 with a power of about 1540-1560 megawatts due to restrictions set by Fingrid, Finland’s transmission system operator. However, after weeks of shutdown due to a fault in the generator’s cooling system and other issues limiting electricity production and transmission capacity earlier this year,
