KEY CONTEXT

How should the electricity mix of Belgium be read?

Latest figures

In 2025, net generation is 66 600 GWh. The main shares are: renewables 39.5 %, nuclear 33.7 %, fossil fuels and other 26.8 %.

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.
