On Wednesday, November 22, at one o’clock in the morning, the Olkiluoto triple reactor will resume full production of electricity on the Nordpool electricity exchange. The reactor’s electricity production was temporarily halted on Sunday evening.
According to TVO’s announcement, the power plant will begin producing electricity at 1285 megawatts on Tuesday at 12 o’clock. 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 by 2 p.m. today.
Johanna, Teollisuuden Voima’s communications manager, stated that if a fault is detected in the turbine plant, they will immediately inform customers about it when they have more details. However, Johanna does not speculate about the cause of the failure but emphasizes that it is not similar to last spring’s trial run but specifically a failure that occurred during use.
After years of problems and delays, Olkiluoto finally started regular electricity production in spring 2017 with a power output of around 1540-1560 megawatts due to Fingrid restrictions. In August, Olkiluoto’s second reactor stopped for weeks due to a fault in its generator cooling system and other factors that limited electricity production and transmission capacity. These factors caused fluctuations in the price of electricity on the stock market at that time.
