After a brief suspension in electricity production, the Olkiluoto triple reactor is set to resume operations at full capacity on Wednesday morning. The reactor’s electricity production was halted on Sunday evening due to an unknown issue with the turbine plant. According to TVO’s announcement, the power plant will start producing electricity at 1285 megawatts on Tuesday at noon.
If this happens, the decommissioning of the nuclear power plant will be reflected in the price of electricity immediately, as tomorrow’s electricity will be sold in Nordpool by 2 p.m. today. TVO’s communications manager, Johanna, stated that they will inform about the fault of the turbine plant as soon as they have more information but did not speculate on its cause.
The Olkiluoto power plant has had years of problems and delays since it started regular electricity production in the spring of this year with a power of about 1540-1560 megawatts due to restrictions set by Fingrid. The second reactor stopped for weeks in August due to a fault in the generator’s cooling system and other factors that limited electricity production and transmission capacity, causing fluctuations in the price of electricity on the stock market at that time.
