TVO: Olkiluoto’s Electricity Production Challenge Classified as Short-Term Problem


Nov 21, 2023

The Olkiluoto triple reactor, which has been producing electricity since the spring of this year, will resume full production on Wednesday at one o’clock in the morning. After years of problems and delays, the plant is running normally with a power of about 1540-1560 megawatts.

However, the reactor’s electricity production was suspended on Sunday evening due to an unexpected fault in one of its turbines. According to Teollisuuden Voima’s communications manager, Johanna, the company will inform about the fault as soon as it has more information on the matter. She emphasized that it is not a problem similar to last spring’s trial run but specifically a failure that occurred during use.

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., according to TVO’s announcement. If this happens, it means that there will be no more electricity from Olkiluoto until Wednesday morning when full production starts again.

It is worth noting that Olkiluoto’s second reactor stopped for weeks in August due to a fault in the generator’s cooling system and other things that limited electricity production and transmission capacity. This resulted in fluctuation of the price of electricity on the stock market at that time.
