KEY CONTEXT

How should the electricity mix of Slovakia be read?

Latest figures

In 2025, net generation is 27 169 GWh. The main shares are: renewables 17.8 %, nuclear 65.9 %, fossil fuels and other 16.3 %.

What the indicator measures

The electricity mix divides net generation into major families. Renewable, nuclear and “fossil fuels and other” shares are designed to add up to total generation.

Important distinction

A source’s share of generation is not the same as its installed capacity. A technology can account for many MW but a different share of annual GWh.
