Teollisuuden Voima Oyj’s Interim Report 1 January–30 June 2023
During the first half of 2023, Teollisuuden Voima Oyj’s (TVO) electricity generation at the Olkiluoto 1 (OL1) and Olkiluoto 2 (OL2) plant units continued safely and reliably. The test production programme for the Olkiluoto 3 EPR plant unit (OL3) was completed, and regular electricity production started on 16 April 2023.
TVO confirmed the provisional takeover of the OL3 plant unit for the warranty period which started on 18 April 2023; commercial operation started on 1 May 2023. OL3 significantly improves Finland’s self-sufficiency in terms of electricity and helps in achieving the goals for carbon neutrality. OL3 has been generating electricity according to plan. For the time being, the grid operator Fingrid Oyj has limited OL3’s production to a maximum of 1,570 MW. Furthermore, output at all three Olkiluoto plant units has been reduced in situations where electricity generation has been high in the Nordic countries.
The processing of Posiva’s operating licence has progressed at the Radiation and Nuclear Safety Authority (STUK), and Posiva is submitting responses to the requests for additional information. Work with the installation and commissioning of systems at the encapsulation plant has progressed as planned. In the first actual deposition tunnel, investigations are underway relating to verifying the suitability of the tunnel and defining the locations of the deposition holes for the final disposal of nuclear fuel.

Teollisuuden Voima Oyj has produced electricity for its shareholders, Finnish industrial and energy companies, safely and reliably for over 40 years. Nuclear electricity generated at TVO's Olkiluoto plant covers approximately 30 percent of Finland’s electricity demand once Olkiluoto 3’s regular electricity production has started. Climate-friendly nuclear electricity not only benefits society but also reduces the environmental impact of energy production. Moreover, the world's first final disposal facility for spent nuclear fuel is under construction in Olkiluoto.
