Electricity in Slovakia in 2023/2024

Slovakia stands as a shining example of clean electricity generation, with more than 87% of its electricity derived from low-carbon sources over the period from November 2023 to October 2024. Dominating this green energy mix, nuclear power contributes nearly 60%, while hydropower adds more than 21% to the national grid. Solar energy also plays a role, albeit on a smaller scale, with roughly 2% of electricity generation. On the other hand, Slovakia relies minimally on energy sources derived from fossil fuels; gas provides a little under 7%, and coal and oil each contribute just over 1%. Crucially, Slovakia’s commitment to exporting electricity assists its neighbors in reducing emissions, further amplifying the country's contribution to a low-carbon future. Looking ahead, Slovakia faces the task of expanding electrification into other sectors such as transportation, heating, and industry to further drive down emissions and foster a sustainable society.

Suggestions

To meet the growing demand for clean electricity, Slovakia can seize the opportunity to enhance its low-carbon generating capacity, particularly by expanding its nuclear energy infrastructure. Given the substantial contribution of nuclear power to the country’s existing energy mix, further investment in this sector could rapidly scale up green electricity output, positioning Slovakia as a leader in sustainable energy. Additionally, exploring advancements in solar technology could complement the already significant contributions from nuclear and hydroelectric power. By prioritizing these areas, Slovakia can ensure a robust, reliable, and environmentally benign electricity supply that paves the way for a full transition to low-carbon systems across all sectors.

History

A review of Slovakia’s historical journey with low-carbon power reveals a series of strategic advancements over the decades. Noteworthy progress was made in the 1980s and 1990s, exemplified by the substantial increase in nuclear output in 1986 with an addition of 2.3 TWh, and again in 1994 with an increase of 1.1 TWh. However, this was followed by a few setbacks such as the minor reduction in 1995 and significant downturns like the 2.7 TWh decrease in 2007 and the 2.6 TWh fall in 2009, which highlight the need for more stability and expansion in nuclear generation. Post-2010, Slovakia resumed positive momentum, with notable nuclear gains in 2011 and 2023, each adding nearly 1 TWh and 2.4 TWh respectively. Concurrently, hydropower witnessed fluctuations, marked by increases such as in 1993 and notable fluctuations through to 2023-2024, where it rebounded with an impressive 2 TWh rise. This historical context underscores the potential of maintaining and augmenting the focus on nuclear energy while managing hydropower to secure reliable and environmentally-conscious electricity production.
