Spain has 829 power plants in this atlas, with 79,035 MW of reported capacity. The largest listed plant is CN ALMARAZ 1 (2,017 MW, nuclear; current status unverified). By number of records the most common technologies are wind, solar and hydro. Grid operators listed here include Red Eléctrica. Electricity is regulated by CNMC. Renewables supplied 57.3% of its electricity in 2024.
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.
Grid operators and electricity market 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.

Spain occupies most of the Iberian Peninsula, with a high interior plateau framed by mountain ranges and long Atlantic and Mediterranean coasts. Its Balearic and Canary islands introduce separate island geographies to the atlas.
