Loviisa power plant environmental report: Our environment 2022
Loviisa power plant – reliable and clean electricity production
Clean energy production and sustainability are at the core of Fortum’s strategy. In 2022, the Loviisa power plant generated a total of 7.9 TWh (net) of carbon-free power, corresponding to more than ten per cent of the energy generation in Finland.
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 over nuclear power’s lifecycle are equivalent to those of wind, hydro and solar power.
The environmental work of the Loviisa power plant is guided by the environmental standard ISO 14001. The system covers all operations by the Loviisa power plant and its contractors who work at the island of Hästholmen. As a result of the Loviisa nuclear power plant’s electricity production, Finland emits about 6 million tonnes less carbon dioxide emissions compared to the equivalent amount of fossil fuelbased electricity.
The safety condition of the power plant remained good, and both the production and equipment availability was at a very high level. Excellence in plant safety is an absolute prerequisite of safe and efficient operations for employees and the environment, and it is a sign of professionalism.
In 2022 we stayed within all permit limits in terms of environmental impacts.
In March 2022, Fortum submitted the Loviisa nuclear power plant operating licence application to the Finnish Government. Fortum applied for a new operating licence for both nuclear power plant units until the end of 2050 and for a licence to use the low- and intermediate-level radioactive waste final disposal facility located in Loviisa’s power plant area until 2090. The Government granted a new operating licence in February 2023
