Nuclear power
Nuclear power plays an important role in clean energy production. As a reliable, CO2-free energy source, it helps satisfy today’s electricity needs and improve the security of supply while mitigating climate change. Over its lifecycle, nuclear power has a carbon footprint as low as wind, hydro and solar power.
CO2-free for climate
Nuclear power generates electricity without releasing harmful emissions into the air and helps to achieve carbon neutrality targets.
Stable and reliable
Our nuclear power plants provide a steady and reliable supply of electricity to the society. It improves energy self-sufficiency and security of supply.
Proven safety
Multiple isolation, redundancy and extensive training ensure that nuclear power is safe.

Reliable and clean power for Finland's needs, far into the future
Clean energy
Climate change and the transition to a low-carbon energy system means that reliable, emission-free power generation is more important than ever. As a CO2-free energy production method, nuclear power is a key part of our strategy for a clean-energy future and supports achieving Finland’s and Europe’s carbon neutrality targets.
Always on
A steady source of electricity is critical during periods of increased energy consumption. And unlike other CO2-free production methods, we can count on nuclear power because electricity is generated at a consistent rate regardless of weather conditions. Nuclear helps to improve energy self-sufficiency and security of supply.
+45 years of safety
Extensive employee training with our plant operation simulator continues to strengthen our safety-oriented work culture and large annual investments in plant modifications ensure that all aspects of daily operation are considered as we continuously improve safety.
Nuclear power and the environment
The main environmental impact of nuclear power is related to building the plant, fuel procurement and the thermal load of cooling water discharged into the sea during operation.
