On Wednesday, November 22, at one o’clock in the morning, the Olkiluoto triple reactor will begin full production again on the Nordpool electricity exchange. The announcement from The Power of Industry (TVO) stated that the reactor would start producing electricity at 1285 megawatts on Tuesday at 12 o’clock. If this happens, it 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 by 2 p.m. today.
According to Johanna, Teollisuuden Voima’s communications manager, when more details are known about the fault of the turbine plant, they will immediately inform about it. However, she does not speculate on its cause but 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 has been running normally with Fingrid due to restrictions set by the company with a power of about 1540–1560 megawatts for weeks now. The second reactor stopped for weeks in August due to a fault in its generator’s cooling system. At the same time, there were other things that limited electricity production and transmission capacity, which together fluctuated the price of electricity on the stock market at that time.
