Reported capacity is the rated size of the listed installations, not electricity being produced now. Source dates and coverage differ, so newer facilities may be absent and historical records may remain.
How electricity works in Portugal
Liberalised marketCompetitive generation and retail
Wind, hydro and solar supply most electricity. Portugal and Spain share the Iberian market MIBEL, run by OMIE for day-ahead trading.
Part of the synchronous grid of Continental Europe, the largest interconnected grid in the world by customers, coordinated by the European Network of Transmission System Operators for Electricity.
What does “Liberalised market” mean?
Generators sell into a wholesale market, an independent operator runs the transmission grid, and households can choose their electricity supplier. Networks stay regulated monopolies because building parallel power lines makes no sense.

On the Atlantic edge of the Iberian Peninsula, Portugal connects a mountainous north with the broad plains of the Alentejo. The Azores and Madeira extend its geography into the Atlantic. Explore how hydroelectric stations follow river valleys while wind and solar sites occupy very different landscapes.
