Loviisa nuke plant covers 10% of electricity consumption in Finland

The Loviisa nuclear power plant produced a total of 7.9 terawatt hours of electricity In 2024, said Fortum in a press release on Friday.

The plant's electricity production accounts for about 10% of the electricity consumed in Finland, which is nearly equivalent to the electricity consumption of the entire Helsinki metropolitan area.

The load factor of the Loviisa power plant was 88.3 in 2024. The load factor of Loviisa 1 was 86.6% and of Loviisa 2 was 90.0%.

In addition to the extended duration of planned annual outages, production was also reduced by an unscheduled four-day production shutdown of Loviisa 2 in November. Unit 1 underwent an extensive four-year outage last summer, while Unit 2 had a short annual outage.

"Overall, the year's targets were reasonably well achieved, and we managed to carry out the planned maintenance and modifications during the annual outages. One of our most significant achievements was the introduction of new Westinghouse nuclear fuel to the plant," said Sasu Valkamo, Senior Vice President of the Loviisa power plant.

Fuel supply diversification has been an important project at the Loviisa power plant. During the annual outage, the second reactor was loaded with the first batch of nuclear fuel supplied by the American Westinghouse Electric Company. The new fuel ensures a reliable western alternative for the Loviisa power plant's fuel supply.

"Also, our long-term and systematic work to reduce radiation levels for radiation workers has yielded significant success. Once again, during last year's annual outages, we achieved record low radiation doses," Valkamo added.
