KEY CONTEXT
How should the electricity mix of Spain be read?
Latest figures
In 2025, net generation is 277 894 GWh. The main shares are: renewables 54.9 %, nuclear 18.7 %, fossil fuels and other 26.5 %.
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.
