The annual maintenance of Industry Voima’s (TVO) Olkiluoton nuclear power plant’s triple reactor has been extended by two days due to technical problems, according to the updated schedule. Initially, TVO estimated that the maintenance would be completed on May 8, but it has now been extended to May 10. The simultaneous annual maintenance of Olkiluoto 3 and Olkiluoto 2 has caused two of TVO’s nuclear reactors to be out of the electricity market at the same time. This has had an impact on the price of electricity, causing a spike in prices on the exchange.
The annual maintenance of Olkiluoto 3 began in early March and was originally scheduled to end on April 8. Delays in the past have been caused by various technical issues with inspection equipment and new defects found during maintenance. The unit is being carried out for the first time, and it accounts for more than ten percent of Finland’s electricity production. The extension of the maintenance period is a significant development for the plant and will have implications for the electricity market during this time.
