The Olkiluoto triple reactor, which had been suspended from electricity production on Sunday evening, is set to resume full production again on Wednesday at one o’clock in the morning. According to an announcement from TVO, the reactor will start producing electricity at a capacity of 1285 megawatts on Tuesday at 12 o’clock. This means that the decommissioning of the nuclear power plant will be reflected in the price of electricity only on Tuesday, as tomorrow’s electricity will be sold in Nordpool by 2 p.m. today.
Teollisuuden Voima’s communications manager, Johanna, stated that the company would immediately inform about the fault of the turbine plant when more details are known. However, she did not speculate on the cause of the failure but emphasized that it is not a problem similar to last spring’s trial run but specifically a failure that occurred during use.
The Olkiluoto plant has faced years of problems and delays and finally started regular electricity production in spring this year with a power of about 1540-1560 megawatts despite restrictions set by Fingrid due to its limitations. In August, Olkiluoto’s second reactor stopped for weeks due to a fault in its generator’s cooling system and other issues that limited electricity production and transmission capacity, which fluctuated the price of electricity on the stock market at that time.
