OL3 EPR's regular electricity generation starts in July 2020

Teollisuuden Voima Oyj (TVO) has received an updated schedule for the commissioning of the OL3 EPR plant unit from the plant supplier Areva-Siemens Consortium. According to the received information, the regular electricity generation at the OL3 plant unit will start in July 2020.

In spring 2019, the plant supplier Areva-Siemens Consortium announced that it will update the schedule for completing the Olkiluoto 3 EPR project since the modification outage work carried out at the plant unit was not progressing as expected and that it will provide an updated schedule to TVO in summer 2019.

According to the plant supplier, nuclear fuel will be loaded into the reactor in January 2020, the first connection to the grid will take place in April 2020, and the start of regular electricity production of the OL3 EPR nuclear power plant unit will take place in July 2020. According to the commissioning program, the unit will produce 1-3 terawatt hours with varying power levels during the test program, which will begin from the connection to the grid and will end to the beginning of regular electricity production. Regular electricity production was previously planned to start in January 2020.

The re-baseline schedule has been updated with the plant supplier, who still remains responsible for keeping the schedule.

- The re-baseline is now more exhaustive which we believe will make it possible to improve project performance. The scheduling work was not only a schedule updating exercise, but it consisted of methodology to change the ways of working. Although, the completion of the plant unit will be further delayed, we are currently working to reach the fuel loading phase and to take over the OL3 EPR unit, says Jouni Silvennoinen, TVO's Director of the OL3 EPR Project.

OL3 plant supplier consortium is constructing the plant unit under a fixed-price turnkey contract. The supplier consortium companies, AREVA GmbH, AREVA NP SAS and Siemens AG, have joint and several liability for the contractual obligations until the end of the guarantee period of the plant unit.

Teollisuuden Voima Oyj has produced electricity for its shareholders, Finnish industrial and energy companies, safely and reliably for 40 years. Nuclear electricity generated at TVO's Olkiluoto plant covers approximately one sixth, increasing to nearly one third once Olkiluoto 3 is completed, of the electricity consumption in Finland. 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.
