Nuclear Nuclear power plays an important role in clean energy production. As a reliable, CO2-free energy source, it helps satisfy today’s increasing electricity needs while mitigating climate change. Over its lifecycle, nuclear power has a carbon footprint as low as wind, hydro and solar power. 10 things about nuclear power 10 things to know about nuclear power in the 2020s Read more Low emissions CO2-free for climate Nuclear power generates electricity without releasing harmful emissions into the air. Reliable Stable and reliable Our nuclear power plants provide a steady and reliable supply of electricity to the society. Safety Proven safety Multiple isolation, redundancy and extensive training ensure that nuclear power is safe. The world is changing 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. 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. 40 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. 4,848 MW nuclear generation capacity 28.6 TWh nuclear power produced 20% share of Fortum's total power generation Small modular reactors – nuclear power’s new flexible generation Nuclear power is a future energy form that is constantly developing, and small modular reactors are an example of the latest innovations in the sector.
