Nuclear energy is increasingly being prioritized in South-East Europe as governments actively seek to enhance long-term energy security and decarbonize their electricity sectors. Developments anticipated in April 2026 signal a renewed commitment to nuclear investment, modernization, and the bolstering of fuel supply chains across the region.
Currently, nuclear power contributes approximately 21% of total electricity generation in South-East Europe, highlighting its critical role as a stable baseload energy source. Unlike renewable energy sources, which can be intermittent, nuclear facilities provide consistent output, thereby supporting grid stability and decreasing reliance on fossil fuels.
Romania is leading the way in this resurgence of nuclear energy. The state-owned company Nuclearelectrica has initiated a feasibility study aimed at doubling its production capacity of CANDU nuclear fuel. This initiative not only aims to strengthen domestic supply chains but also aligns with broader European efforts to secure essential energy resources and reduce dependency on external suppliers.
In Serbia, nuclear energy has re-entered the national dialogue with plans to make a decision regarding the construction of the country’s first nuclear power plant by 2032. This development marks a significant shift in Serbia’s energy strategy, reflecting an increasing acknowledgment of nuclear power’s potential to ensure long-term supply stability while also aiding in achieving decarbonization targets.
Bulgaria and Romania continue to operate existing nuclear facilities that play crucial roles in regional electricity supply and cross-border power exchanges. These plants are essential for stabilizing wholesale electricity prices and facilitating integration within the European grid.
The renewed focus on nuclear energy is particularly relevant given the rising geopolitical tensions and fluctuating fossil fuel markets that have characterized recent years. As Europe strives to lessen its dependence on imported fuels, nuclear power emerges as a low-carbon alternative that can deliver reliable output over extended periods.
Moreover, nuclear energy is increasingly viewed as complementary to renewable sources. By providing firm baseload capacity, it allows for greater integration of intermittent solar and wind generation without jeopardizing grid reliability.
Investment in nuclear infrastructure brings additional economic advantages such as job creation, technological advancements, and industrial growth. As governments reassess their long-term energy strategies, nuclear power is becoming an essential element of sustainable and secure electricity systems across the region.
With ongoing feasibility studies, modernization initiatives progressing, and policy discussions intensifying, nuclear energy is poised to play a pivotal role in South-East Europe’s transition towards a resilient and low-carbon future.
