TVO evaluates Olkiluoto’s electricity production challenges as temporary


Nov 21, 2023

The Olkiluoto triple reactor, which was temporarily shut down on Sunday evening due to a fault in the turbine plant, is set to resume full production again on Wednesday at one o’clock in the morning. According to TVO’s announcement, the reactor would start producing electricity at 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 will immediately inform about the fault of the turbine plant when it is known in more detail. However, she emphasized 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 finally started regular electricity production in the spring of this year with a power of about 1540-1560 megawatts due to restrictions set by Fingrid. Despite this, there were other things that limited electricity production and transmission capacity in August due to a fault in the generator’s cooling system and other issues that fluctuated the price of electricity on the stock market at that time.
