Finland’s first nuclear power plant, unit one of Fortum’s Loviisa power plant, was connected to the national grid exactly 40 years ago, on 8 February 1977, and electricity production for commercial use commenced in May 1977. Unit two was completed about three years later and was connected to the national grid in November 1980. Throughout its history, the Loviisa power plant has produced a total of 288.2 terawatt hours, equivalent to the annual consumption of over 17 million single-family homes heated with electricity.
“The first Finnish nuclear power plant is a result of the combining of Eastern, Western and Finnish technology; the outcome is the Loviisa power plant. The excellent operational history, international-level load factors and outstanding safety record make it verifiably one of the world’s best nuclear power plants in terms of availability,” says Thomas Buddas, Deputy Director, Loviisa Power Plant.
To date, the average lifetime load factor for unit 1 is 86.9% and 88.6% for unit two. The average load factor for both units is 87.7%. The load factor describes the plants’ production during a certain period of time compared to the nominal capacity. The nominal capacity of the plant units has been increased through several upgrades that have improved the plant’s safety and reliability. Today each plant unit has a gross power capacity of 526 MWe; the original capacity of the units was 440 MWe.
“The Loviisa Power Plant is developed in line with the continuous improvement principle. The plant’s most extensive investment programme ever is currently under way and will secure safe, reliable and profitable electricity production to the end of the units’ operating licenses, i.e. 2027 and 2030,” Buddas continues.
As a producer of clean energy, the Loviisa power plant and carbon-free nuclear power play a significant role in mitigating climate change. The greenhouse gas emissions during nuclear power’s lifecycle are as low as those for wind, hydro and solar power. If the electricity generated by the Loviisa power plant over the course of its operating lifetime would have been generated in a coal condensing plant, about 230 million tonnes of carbon dioxide would have been released into the atmosphere.
During Loviisa power plant’s construction phase in the 1970’s, there were some 3,000 people working on Loviisa’s Hästholmen island. Today about 500 Fortum employees and nearly 100 permanent employees from other companies work at the
plant every day.

Loviisa power plant
In 2016, the load factor at Fortum’s fully-owned Loviisa nuclear power plant was 91.1%. On an international scale, the load factor was among the best in the world for pressurised water reactor power plants. The plant produced a total of 8.33 terawatt hours, which is approximately 13% of Finland’s total electricity production. The Loviisa power plant employs approximately 500 Fortum employees and 100 permanent contractors. In 2016, Fortum invested EUR 100 million into the Loviisa nuclear power plant.
