The Nordpool electricity exchange has been informed by Teollisuuden Voima (TVO) that the Olkiluoto triple reactor will resume full production on Wednesday, November 22 at one o’clock in the morning. The reactor’s electricity production was halted on Sunday evening.

According to TVO’s announcement, the plant will begin producing electricity at 1285 megawatts from Tuesday at noon. 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 pm today.

Johanna, communications manager for Teollisuuden Voima, says that the company will immediately inform about any faults with the turbine plant when more details become available. However, she does not speculate on the cause of failure and emphasizes that it is not a problem similar to last spring’s trial run but specifically a failure that occurred during use.

After years of problems and delays, Olkiluoto is now operating normally according to Fingrid’s restrictions with a power output of approximately 1540-1560 megawatts. In August, Olkiluoto’s second reactor stopped for weeks due to a fault in its generator’s cooling system. Other factors also limited electricity production and transmission capacity, which caused fluctuations in the price of electricity on the stock market at that time.
