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 Spain
Liberalised marketCompetitive generation and retail
Wind and solar now supply around half of electricity. OMIE runs the Iberian day-ahead market; households can choose the regulated PVPC tariff, which follows hourly prices.
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.
