Finland needs new nuclear plants.

Country Needs New Large-Scale Nuclear Power Plants, Says Energy Technology Expert

As the use of renewable energy sources continues to grow, the need for baseload power is still essential. This has led to discussions about the possibility of constructing new nuclear power plants in Loviisa and Olkiluoto. The importance of this initiative is emphasized by Esa Vakkilainen, a professor of energy technology at Lappeenranta University of Technology.

Vakkilainen believes that Finland needs to prioritize the construction of new nuclear power plants before existing ones are retired for good. He proposes that the country should aim for a 50% share of nuclear energy in electricity generation, a substantial increase from the current 35%.

Necessity for New Nuclear Power Plants

The push for new nuclear power plants comes as a response to the increasing demand for reliable and sustainable energy sources. With growing concerns about climate change, nuclear energy is considered an important component of the clean energy mix.

Vakkilainen’s advocacy for a higher percentage of nuclear energy in Finland’s electricity generation aligns with the country’s commitment to reducing carbon emissions and transitioning to a greener economy.

Benefits of Nuclear Energy

Nuclear energy offers several advantages, including its ability to provide a consistent and reliable baseload power supply. This stability is crucial for meeting the energy demands of a modern society while reducing reliance on fossil fuels.

Furthermore, nuclear power plants produce electricity without emitting greenhouse gases, making them a key player in the shift toward cleaner energy production.

Challenges and Considerations

Despite its benefits, nuclear energy also poses challenges, particularly in terms of waste management and safety. Addressing these concerns is essential for the successful implementation of new nuclear projects.

Additionally, the financial and regulatory aspects of building and operating nuclear power plants require careful consideration and planning. This includes ensuring the highest standards of safety and security throughout the entire lifecycle of the facilities.


The potential for new large-scale nuclear power plants in Finland presents both opportunities and challenges. As the country strives to increase its share of nuclear energy in electricity generation, it must navigate various technical, economic, and societal factors to ensure a sustainable and secure energy future.

By embracing the expertise of energy technology professionals like Esa Vakkilainen and continuously evaluating the role of nuclear power in the broader energy landscape, Finland can make informed decisions that support its energy goals while contributing to global efforts in combating climate change.
