The electricity production of the Olkiluoto power plant units, OL1 and OL2, during 2018 was 14,089 (13,415) GWh. The total load factor was 91.1 (87.2) %.
The plant units operated safely. OL1's net production was 6,755 (7,158) GWh and load factor 87.8 (93.1) %. OL2's net production was 7,334 (6,256) GWh and load factor 94.3 (81.3) %.
The production of the OL2 plant unit was the third best result ever in the history of the unit. The production volume and load factor of OL1 did not rise as high as in the previous years due to some major modification and repair works carried out during the annual outage. Thanks to the modifications the nominal output of OL1 was increased from 880 megawatts to 890 megawatts at the turn of the year.
The Finnish Government approved the extension of operating licences for OL1 and OL2 plant units to be continued up till the year 2038. The Government decision was preceded by the statement of the Radiation and Nuclear Safety Authority (STUK) issued in May. According to STUK, the operation carried out by TVO is safe and in conformity with the law, and the Company has the required capabilities, procedures, expertise and resources for the safe continuation of the operation of the OL1 and OL2 plant units up till the year 2038.
